Disclosures
• No financial disclosures.
Case Review
• 49M with history of ulcerative colitis, underwent total colectomy with end ileostomy Nov 2009.
• Post-op course initially uneventful. Activity level limited due to perineal reconstruction. Required to be flat in bed.
• POD#10, witnessed emesis with aspiration. Subsequent respiratory, then cardiac arrest. Perfusing rhythm regained after 5 minutes of CPR.
• Worsening hypoxia despite high level ventilatory support.
• Decision made to proceed with ECMO support. Cardiac surgery contacted, and RIJ-RFV VV ECMO initiated.
• Gradual improvement in CXR, gas exchange.
• Decannulated 10 days later.
History of ECMO
• 1953 Gibbon: first successful use of cardiopulmonary bypass
• 1967 Kolobow: developed spiral coil membrane
• 1976 Bartlett: first successful neonatal ECMO (UC Irvine)
• 1980 Bartlett: established first neonatal ECMO Program (University of Michigan)
• 1986: 18 neonatal US ECMO centers, 700 cases
• 1989: Extracorporeal Life Support Organization (ELSO) established
• 2009: CESAR trial, H1N1 influenza pandemic
Acute Mechanical Circulatory Support (MCS)
• Heart support
– Balloon pump, Impella, VAD/BiVAD, VA ECMO
• Lung support
– VV ECMO, AV ECMO (pumpless), ECCO2R, VA ECMO
• Heart and lung support
– VA ECMO, Cardiopulmonary bypass
Bearings
• CentriMag: True MagLev
• Rotaflow: Sapphire bearing
• Cardiohelp (HLS Set Advanced integrated oxygenator/pump): Rotaflow with Quadrox, with sapphire bearing
• Sorin Revolution pump: HDPE (High Density Polyethylene) bearing
• TandemHeart: "Hydrodynamic Bearing" but the impeller and rotor have separate housings, and needs purge solution
• TandemHeart LifeSPARC: “Magnetic pivot bearing” (ruby)
Coatings
• Maquet Safeline: Synthetic albumin
• Maquet Bioline: Recombinant human albumin and heparin
• Maquet Softline: Synthetic surface coating (Glycerol-polyethylenglycol-rizinoleate)
• Terumo Xcoating: Synthetic surface coating (Poly2methoxylacrylate)
• Medtronic Balance Biosurface: Hydrophilic polymer coating without heparin
• Medtronic Trillium: Hydrophlic polymer coating with covalent heparin bonding
• Medtronic Cortiva BioActive Surface: formerly called Carmeda, polymer deposit and covalent heparin bonding
PMP
• Current generation oxygenators are hollow fiber (membrane) oxygenators, and the ones used for ECMO are almost always made with Polymethylpentene (PMP) which drastically reduces plasma leakage.
• PMP is sometimes called TPX (trademark of Mitsui Chemicals). If a standard CPB membrane is used for ECMO, it would start frothing and fail within a day or so.
Patient selection
Cardiopulmonary Support Considerations
• Mode of failure and required support
• Level of urgency
• Inotropes and pressors
• Cannulation location
• Cannulation site
• Required flow
• Percutaneous vs open
• Peripheral vs central
• Central venous access, access for ultrafiltration
• Airway stability, anesthesia requirements
Forms of ECMO
• V-V
• V-A
• VV-A, V-AV / V-VA
• A-V
• VVV-A, V-AA, VV-AA
• A-A!
Cannulation sites
• Femoral artery & vein
• Internal jugular vein
• Axillary/Subclavian artery & vein
• Carotid artery
• Central: aorta, right atrium, pulmonary artery, LV apex, left atrium
Peripheral VA ECMO
• 17-21F arterial cannula
• 8F distal perfusor
• 23-27F venous cannula
Percutaneous RIJ cannulation
• Ultrasound guidance sufficient for short outflow cannula
• Fluoroscopy: necessary for placement of multi-stage drainage cannula into IVC, placement of percutaneous PA cannula
• Placed percutaneously with fluoroscopy and TEE guidance.
Bicaval dual lumen cannula (Avalon)
OxyRVAD / RA-PA ECMO Axillary artery cannulation
• Open, with 8-10 mm graft to axillary artery
• Long-term ambulatory VA ECMO
Percutaneous subclavian artery cannulation BiVADs without sternotomy
LVAD: LV apex cannulation with mini-thoracotomy, axillary cut-down with graft and arterial cannula placement.
RVAD: Percutaneous RA-PA via RIJ.
BiVADs without sternotomy BiVADs with Protek Duo cannulas
Bleeding at cannulation sites
• All sites can bleed!
• Cannulation site bleeding sometimes requires surgical management.
Bleeding on ECMO
• Due to:
– Coagulopathy related to extracorporeal circulation: consumption, platelet dysfunction (acquired Von Willebrand disease).
– Access to major vessels.
– Often post-op, or invasive procedures required.
• Key points to reduce bleeding after ECMO cannulation:
– Technically sound cannulation.
– Close monitoring, with consideration of clinical status.
– Prompt attention to bleeding, or evidence of blood loss.
– Bleeding is much more common than clotting. Coagulopathy should be reversed, and bleeding should be stopped early.
• Monitor using PTT, anti Xa, and ACT as needed, with clinical correlation.
• Thromboelastography (TEG) also used.
37
Considerations after cannulation
• Adequate level of support
• Speed / hemolysis
• Maintenance of pulsatility / LV ejection / LV unloading
• Weaning of inotropes and pressors
• Early conversion to ambulatory ECMO, extubation, mobilization
Summary
• Dr. Bartlett’s career IS the history of ECMO!
• Current generation pumps and circuits have greatly facilitated ECLS, and have decreased complications.
• The type of support needed, and urgency, will determine cannulation strategy.
• Sound cannulation technique and attention to detail is important to provide adequate circulatory support, and minimize complications.
• Plans for transition to other forms of support should be taken into account time of initial cannulation.
Thank you!

Growth of Adult Cardiac ECMO
15Guglin M. JACC 2019
Why Would Devices Work in Cardiogenic Shock?
• Availability of durable membranes and portable circuits
• Ability of VA‐ECMO to provide left, right, and biventricular support
• Ease of implantation in the catheterization laboratory or at the bedside
• Increased familiarity with the technology by cardiologists and surgeons
• The need for a short‐term bridge to transplantation or mechanical support
16
Common Objectives for VA ECMO
• Bridge to recovery:– Temporize circulatory support while definitive and supportive treatment strategies are
deployed to restore myocardial recovery
• Bridge to decision – To determine the reversibility of end‐organ damage commonly seen after a catastrophic or
critical myocardial event or to decide the next level of action
• Bridge to bridge – To achieve a brief stability for end‐organ perfusion until more definitive pump support (durable
mechanical circulatory support)
• Bridge to transplant– To achieve a brief stability for end‐organ perfusion until cardiac transplantation is performed
17
Indications for VA ECMO• Cardiac arrest (extracorporeal CPR) • Cardiogenic shock due to acute MI
• Progression of cardiomyopathy, ischemic or nonischemic
• Acute RV failure due to pulmonary embolism • Progression of RV failure due to pulmonary disease • Progression of congenital heart disease • Primary graft failure and acute allograft rejection after OHT• Overdose of cardiotoxic drugs • Septic cardiomyopathy • Refractory ventricular tachycardia • RV failure during LVAD support • Failure to wean off cardiopulmonary bypass

“Let’s wait until tomorrow for therapy”…
Muscle strength in a healthy individual can decrease 1.3-3% per everyday spent on bedrest
Effects are more profound in older individuals and those suffering from critical illness
3-11% strength loss for every day in bed in an ICU setting o Age and days on bed rest are independent predictors
of worsening function

Backgorund Pediatric in-hospital cardiac arrest (IHCA): 3% in pediatric
ICU, 6% in pediatric cardiac ICU Survival after pediatric IHCA: improved to 35% over the last
25 years Extracorporeal cardiopulmonary resuscitation (ECPR) using
extracorporeal membrane oxygenation (ECMO) contributed to improved survival
Background American Heart Association Pediatric ALS guidelines:
consider ECPR1. Condition leading to cardiac arrest potentially reversible2. Patient is candidate for heart transplantation
Contraindications Existing irreversible neurological injury
Multi-organ failure before cardiac arrest
Irreversible or non-operative primary disease
Extreme prematurity (<32weeks gestation)
Previous parental refusal for the use of mechanical support
Ineffective medical CPR performed out of ICU or out of hospital
Inititation Can be done in ICU, cardiac cath lab, ER, step down unit
ECMO team: ECPR initiated within 5 minutes of cardiac arrest if no return of spontaneous cardiac activity
Medical CPR continued through cannulation
Pre-primed ECMO circuit
ECMO and cannulation equipments
Patient’s preparation
CannulationCannulation site depends on underlying circumstances and patient’s cardiac anatomy:
Central Cannulation: aortic and right atrial done through median sternotomy incision
Peripheral cannulation: femoral, common carotid artery or axillary artery. Femoral or internal jugular vein
Neck Cannulation
Central Cannulation Central Cannulation
Central vs PeripheralAdvantages
Large size cannulas Ease of cannulation
High flow rates Less risk of bleeding in postoppatients
Fast access for emergency Can be done while doing in postcardiotomy patients chest compression Perfuse all parts of the Less risk of wound infection
body Access to decompress left Patient can be extubated andventricle if need be mobilized
Central vs PeripheralDisadvantages
Requires sternotomy for Limited cannulas size and cannulation and decannulation flow rates
Higher risk of infection and Needs special procedures bleeding to decompress LV
Higher chance of ischemic Differential body perfusion emboli (North-South syndrome)
Risk of thrombosis above Lower body ischemia inaortic valve femoral artery cannulation
Generally precludes patient’s extubation and mobilization
Requires interruption of cardiaccompression during cannulation
Cannulation
ECMO cannulation:Specific considerations based on underlying pathology:•Heterotaxy, abnormal venous anatomy•Bidirectional Glenn, Fontan•Vessel occlusion from previous cath or surgery
CannulationECMO cannulation, assessment of adequacy of flow:Specific considerations based on underlying pathology:
S-P shunts: increase flow rates to 200ml/kg/min
Partial shunt clamping vs use the shunt in patients with no lung pathology
ECPR ECMO Hypothermia: Temp 35°C, warm up by 0.5°C every 6
hours after 24 hours
Reoxygenation injury: start with FiO2 21%, go up slowly, maintain PaO2 35-45 in patients with mixed circulation.

• It’s expect• We even k
October 28, 2019 7
Let’s Consider….
• Over the last 10 years, ECMO has been used forpulmonary indications in over 4,000 pediatric patients, for an average duration of 11 days, with 59% survival tohospital discharge
• In the past, if RV heart failure or no lung recovery occurred after 20‐30 days of ECLS, ALI was consideredirreversible, ECMO was discontinued, and the patientdied
What can we learn about what to do with’limits’ from pediatric cardiac ECMO?
• ELSO registry data: If a patient requires ECMO for cardiac support, minimal survival beyond 9 days if there no evidence of cardiacrecovery
• Use of more durable cardiac devices….early• Get up and move!• Improve nutrition!
Is there a ‘limit’ for pulmonary ECMO?
• Several reports of patients being maintained on ECMO for months, year(s)
• Creativity‐alteration of configurations, cannulations, management strategies
• Mobility and nutrition• Lessons learned from patients waiting for heart transplant
• What if we ‘expected’ these patients would need Lung Assist Devices (LAD) if they don’t show recovery in a certain amount of time?
• Would we not only wake them up during the day, but let them sleep at night, walkthem, improve their nutrition….send them home???
The question then becomes…
• Since we can support patients for long periods of time….• Should we? Whom should we support?• For how long?
• If we do…• We need to ‘do’ all aspects exceedingly well
Ethical Aspects of MCS
• Lack of scoring systems for early identification of those most likely torecover
• Disagreements or misunderstandings between health care providersand families/patients and/or each other
• Typically dealing with events that are unexpected, unanticipated• Communication of goals is very difficult, especially when multipleteams are involved
12
Let’s Use a Case as an Example….
• 7 yr old previously healthy female child admitted to the PICU in lateMay 2014
• Sustained 35% TBSA flame burns to R face, R neck, R lower arm, Rhand, R leg and L leg from house fire as well as inhalational injury
October 28, 2019 13
Progressive ARDS• Over 1st week post‐burn, increasing ventilatoryand oxygen requirements
• Significant inhalational injury component with highrisk for secondary bacterial pneumonia
• 5 days after admission, ECHO with elevated RVpressure and iNO started
14
VA ECMO Cannulation
• On post‐burn day 7, during a bedside burndebridement, she went into PEA arrest and was placed on ECMO via the groin (ROSC prior to cannulation)
• left A 13 Fr with 8 Fr reperfusion cannula, right V 17 Fr• 1st cardiac arrest• Phase 1
• She was subsequently febrile and found to be septic with evolvingpneumonia (Pseudomonas)
• Developed limb ischemia despite reperfusion cannula, ultimatelyrequiring left BKA (on ECMO)
October 28, 2019 15
Transition to VV ECMO
• After 6 days of VA ECMO, cardiac recovery achieved and transitioned to VV cannulation
• maintained R groin and cannulated right IJ• Severe lung disease with necrotizing pneumonia, hemopneumothorax
• Ultimately required 5 thoracotomies on ECMO for left chest clean out
• VV ECMO‐phase 2
October 28, 2019 16
VV ECMO….but we need more help• Lung rest settings, but with 100% FiO2 on blender andvent and 12 L/min of sweep gas
• SpO2 was 73‐85% and pCO2 50‐60’s• Significant hemolysis, renal insufficiency
• CXR with complete white out and recurrent bronchoscopies revealed significant airway clots, debris and bleeding
• Ultimately 4 cardiac arrests on VV ECMO

Long VV ECMO Run…Where we do we go from here?
• Recurrent Pseudomonas and fungal sepsis• Renal failure• Persistent need for vasoactive agents• Severe RV dysfunction
• Impacting LV• Lungs improving slowly but will need several months and RV needs to be unloaded
• Mobility with a new amputation is a real challenge• Significant sedation for almost 2 months

On to Phase 3…
• After 54 days of VV ECMO(total 60 days of ECMO)
• RVAD inserted‐phase 3• RA, PA configuration; tunneled
cannulas to allow chest closure (DSC after 4 days)
• CentriMag pump with adultoxygenator

Psychological Aspects
• Counseling sessions
• Memory of events
• Sleep restoration• Lack of sleep‐negative impact on many aspects of health
Time to go home…after 662 days
• Mechanical ventilation• Around the clock• 4‐5 L O2 bled in• Lots of meds‐oral and inhalational
• Peritoneal dialysis• Nighttime
• Home adaptation
• School• Initially home schooling(expected grade!)
• Then half days• Then full days• Then no wheelchair
So what did we/can we learn?• Medical aspects….
• PFC for severe ARDS and use of inhaled factor 7 for DAH, airway obstruction• Alternative pulmonary clearance adjuvants‐cryotherapy
• Regenerative capacity of lungs‐more thanwe have previously believed
• Bivalirudin anticoagulation worked very well and better than heparin
• Earlier use of RVAD configurationwith oxygenator• Reverse remodeling of RV• Early trach and aggressive vent weaning• Enhanced mobility• Impact of renal disease• Quality of life• Continuity providers‐importance for long‐term patients• Resource utilization
• Development of Lung Assist Devices‐we figured it out for hearts….
What about social and ethical lessons?
• All MCS patients should be provided with:
• grief counseling for patients and families• discussions regarding possible end of life‐cardiac arrest, DNR/AND, brain death
• Organ donation on MCS (OP‐ECMO)• ongoing and direct communication about the prolonged physical, cognitive, and emotional effects of ECMO (and whatever resulted in the need for ECMO) on thepatient (and family/surrogate), financial costs, geographic inequalities and thescarcity of ECMO technologies
• palliative and spiritual care, to ease social, physical, and emotional pain and suffering and to accommodate the cultural, religious, and spiritual needs of thepatient
Consider what we are asking….• every healthcare provider who needs to be involved with such critical family (and patient) conversations must acknowledge, and prepare, forthe reality that thoughts about continuing life‐sustaining therapies isvery different when one is dealing with the abstract versus theimpending and immediate reality
• Instead of thinking families and surrogates “change their minds,”understand they are being confronted with new information andneed further guidance and support in decision‐making (e.g., discussions about quality life now versus then)
If you do start down an extended road of MCS….
• Inform the team of ‘why’ and ‘how’• What is the limit? What would make us stop?• Includes multiple disciplines
• Care Conferences can be very helpful• Open it to everyone
• Involve the families whenever possible‐allow them to voice their opinions, concerns, etc…to the group if they want
• Reach out‐we only get better when we learn from each other
Where is she now?• She has been home for over 3 years now• She is now on RA during the day, nasal BIPAP at night, with her trach capped
• ECHO nml with no evidence of pulm HTN, off all medications
• No episodes of bacterial respiratory infectionrequiring readmission
• Physical therapy and dance class• All A’s and B’s!
October 28, 2019 56
This level of support is not sustainable for multitudes of patients….• Financial implications• Resource utilization
• Development of LADs (lung assist devices) that would allow dischargeto home, much like long term VADs
Can we build a bridge?
• Clinical/medical, social, legal, economical and ethical elements ofECMO are all important elements
• We must share our experiences, patient and caregiver stories, both‘good’ and ‘not so good’ to help all of us create shared decision‐making and find a bridge to an agreed upon destination

October 21, 2019
Indications for ECLS
• Reversible process– Irreversible = Alveolar Capillary Dysplasia,
Surfactant B deficiency
– Cystic Fibrosis in acute exacerbation or as a bridge to lung transplant
• Decision based on assessment of current pulmonary status, rate of deterioration, and other rescue therapy options
October 21, 2019
13
Criteria for ECLS
• Patients with marginal or inadequate gas exchange at risk of ventilator induced lung injury
• Patient’s cardiopulmonary status has historically predicted a high mortality
• Failure of less invasive therapy
October 21, 2019
14
Criteria for ECLS
• Respiratory failure:– PaO2 / FiO2 ratio <60-80 x 4 hours
– Oxygenation Index >40 on two ABGs
OI = MAP(cmH2O) x FiO2 x 100_
PaO2 (mmHg)
– Elevated Ventilator pressuresMAP > 20-25 on conventional vent
MAP > 30 on HFOV
Evidence of iatrogenic barotrauma
October 21, 2019
15
Criteria for ECLS
• Hypercapnic ventilatory failure– Sustained respiratory acidosis < 7.1
– Older pediatric patients may benefit from CO2 removal devices in the absence of concomitant hypoxia
– Ventilation Index >40

>14days
– Recent neurosurgical procedure or severe intracranial hemorrhage
– Pre-existing chronic illness with poor long-term prognosis
October 21, 2019
19
Contraindication to ECLS
• High Risk Patients– Infants with pertussis pneumonia or
disseminated herpes simplex virus
– Cytomegalovirus infection
– Severe multiorgan failure
– Severe coagulopathy or thrombocytopenia
– Repeat ECLS
October 21, 2019
20
How Do We Decide?
1. Look at estimated mortality and morbidity from the underlying acute clinical disease process + preexisting comorbidities, with and without ECLS
2. Assessment of rate and direction of clinical compensation over a reasonable time frame
3. Reversibility of acute disease process
4. Likelihood of post-survival quality of life, framed by patient and family’s goals of care
October 21, 2019
21
Pediatric ARDS
• Defined as a condition characterized by non-cardiogenic, new-onset pulmonary infiltrates in the setting of oxygen deficit in patients ranging from infants through young adults
• OI used to define severity– Mild (4 ≤ OI < 8)
– Moderate (8 ≤ OI < 16)
– Severe (OI ≥ 16)
October 21, 2019
22
Pediatric ARDS
• Pediatric ARDS is ~4% of all PICU admissions
• Overall mortality of 18-35%
October 21, 2019
23
Pediatric ARDS
• OI has best discrimination of mortality risk– Moderate ARDS <23%
– Severe ARDS >30%
• OI > 20 with mortality >40%
• Each additional increase in OI by one point led to odds ratio increase in mortality of 1.04

Other Indications For ECLS
• Airway recovery
• Mediastinal masses
• Pulmonary Embolism
• Fluid overload
• Drug overdose
• Burn patients
October 21, 2019
25
Airway Recovery
• Support of tracheobronchial tree– Following tracheobronchial surgery
– Following tracheobronchial trauma
• VV ECLS with low ventilator settings- Minimize positive pressure applied to surgical site
• Extubation in appropriate setting
• Minimal sedation / no paralysis
October 21, 2019
26
Mediastinal Masses
• Anterior Mediastinal Masses– Proximal airway compression with
deformation of trachea
– Loss of negative pressure ventilation leads to collapse of trachea
– Inability to intubate due to compression
• ECLS Circuit always on standby for these procedures
October 21, 2019
27

2 Types:1. IMMEDIATELY LIFE THREATENING COMPLICATIONS2. POTENTIALLY HARMFUL COMPLICATIONS
ELSO Reported Mechanical ComplicationsSource: www.ELSO.org, through July 31, 2019
ECMO Complications – Interesting Facts• National trend of complications decreasing while case volume increasing
• Why ?• Circuit clotting is increasing• Raceway rupture is decreasing• Oxygenator failure has significantly decreased • Heat exchanger malfunction hasn’t been reported in 3 years
• What was least reported but growing the fastest ????
• Although more complications are reported at higher volume centers, compounding problems are more prevalent at lower volume centers.
Role of ECMO Specialist in Emergency Management
• First Responder: Perfusionists and ECMO Specialiststhe pump experts. ‐ CALL THEM
• Identify Problems
• Get Help• Fix Problem – Use the 4 Step Sequence
Dealing With Complications
• They’re going to happen – how to respond• 4 Step sequence or cadence for the ECMO specialist and team• Practice, practice, practice the response: CE, SIM LAB! • Debrief each complication and near‐miss
• Plan/revise for future ECMO runs
Emergency Management Begins With Being Prepared
• Practice Emergency Response
• ECMO Circuit Checks: Hourly, Continuous
• ECMO Cart in room
• ECMO Emergency Kit
ECMO Circuit Checks: Every Hour• Inspect circuit for clots, fibrin, air, leaks• Verify function of each equipment piece: arterial head, oxygenator, transducers, heater, blender, CDI
• Meds and blood products running appropriately• Oxygen tank, ECMO cart, Emergency Kit available • Power cords secure• Bridge flashed• Back‐up equipment available
ECMO Circuit Checks: Continuous Scanning
• Practice: continuous visual scanning
• Visually trace the circuit backwards beginning with the arterial cannulae
• Scan the FLOW and RPM first, then main circuit: Arterial and Venous limbs • Check for stable vitals: BP, HR, Rhythm, PAP, CVP, Pt. Temp
• Check Hardware items: Water Temp, Hemoconc.
• Check meds, ACTs (when necessary)• Repeat …. Repeat….Repeat !!
4‐Step Complication Remediation Sequence
1. Identify the Problem and ASK: Is this an immediate life threatening emergency ? IF YES, then continue…
2. Clamp and Call: Clamp ECMO AV Lines, turn off pump, Call for Help• Remember ‘VBA’: Venous Line, Bridge, Arterial Line• Call: ICU and Surgery attending physician – assign this task to an individual
3. Ventilate or Handbag the patient 4. Fix the problem or get a new circuit
Identify: Clots in Circuit, Thrombosis Clots In Circuit• Visual inspection of all circuit components and tubing• Non‐visual indicators: system pressures, flow issues
• 4 step sequence: Is this an immediate life threatening emergency?• If Yes, follow 4 step sequence and replace clotted component • If No, continue to evacuate clot without coming off ECMO
• It may be OK to continue ECMO flow with minor clots in the circuit, IF:• The clots are on the venous side of oxygenator • No change to flow • Acceptable and minimal changes to pre/post pressures• No changes to anticoagulation strategy and results : clot begets clot
Identify: Cannulae Problem • ECMO Flow is limited by improper placement and/or improper size
• Venous cannulae issue: inconsistent flow, low flow, chattering venous, venous pressure
• Arterial cannulae issue: High post‐membrane pressure, normal venous pressure, lower cerebral sats,
• Verify proper size of cannulae according to IFU
• Verify placement by X‐ray, TTE, TEE, imaging
Identify: Accidental Decannulation• Usually preventable: cannulae properly sutured, tied down, secured• Observe and record depth of cannulae at insertion site• Pump near patient bed and brake engaged• ECMO VA lines and pump are protected from other equipment
• Use line holders, towel clamps, tubing trays, when appropriate• Restrain patient as necessary
• Less common causes: tissue fatigue, extended high line pressure, suture rupture
Manage Accidental Decannulation
• 4 Step Sequence• RN Place direct pressure on site• One cannulae usually OK – USE FOR VOLUME INFUSION• Recirculate ECMO circuit to maintain integrity
Identify: Total Power Loss
• Centrimag circuit will continue to run 1‐6 hours on internal battery• Battery dependent on RPM • Battery indicator with time remaining on console
• Unplug extra monitor from back of console
• Retrieve back‐up console for extended on‐battery time
Identify: Air in ECMO Circuit Identify: Air in ECMO Circuit Ancillary Circuit Air
Ancillary Circuit air is not located in the main arterial or venous limbs of the ECMO circuit
• Isolate the air with clamps • Do not move air to main A or V limb of circuit!
• Aspirate air via stopcock• Clamp, cut, and replace if aspiration is not possible
Identify: Air in ECMO Circuit Venous Air
• Venous Air: air in the main venous limb of the circuit from the venous drainage cannulae to the inlet of the oxygenator
• Small bubbles or airlock?• If small bubbles, aspirate via stopcock • If airlock impeding flow: walk air to venous luer connector • If air constantly entrained from venous cannulae, call attending surgeon and continually evacuate air while maintain flow if possible
Identify: Air in ECMO Circuit Arterial Air
• Arterial Air: air in the main arterial limb of the circuit from the outlet of the oxygenator to the arterial cannulae
• If air has reached the patient: initiate 4‐step emergency sequence and ICU’s massive air embolus protocol
• Head down, cool patient, barbiturate coma, surgeon decides to reverse A&V cannulaes to remove air
• Remove air from circuit utilized recirculation line and/or cartiotomy
• If completely deprimed, retrieve back‐up circuit and exchange
Identify: Oxygenator Failure • Signs: ↑Pre‐membrane pressure, decreased gas exchange, blood leaking from “gas out” port
• Acute vs. Chronic• Acute: Immediate loss of function within minutes • Chronic: Slow loss of function over hours
• Acute: Initiate emergency sequence • Chronic: monitor parameters, change in controlled situation
Identify: Connector or Stopcock Issue
• Causing air entrainment or blood loss?• Can we fix the problem without coming off? (Usually stopcocks)• If air, did it reach the patient? Activate 4 step sequence and Air Embolism protocol
• If blood loss, activate 4 step sequence and replace connector or stopcock
Identify: Pump Malfunction
• Pump is unable to flow due to electrical, software, or other reasons• Verify that pump head is seated properly, check for kinks and obstructions, increase RPMs, verify cannulae placement, clot free
• Can pump recirculate through bridge?
• Activate 4 step sequence, leave circuit intact, move arterial head to new motor drive, reestablish blood flow
Just Remember
• Stay Calm !! STAY CALM !!!!
• Follow the 4‐step sequence • I, C&C, V, F
• You’ll be fine!

Misconceptions
“Palliative Care is the same thing as hospice”
OR
“Palliative care is only for dying people.”
3|
A brief look at where we came from…
4|
• The field of palliative care did arise from the hospice movement.
5|
NEJM, August 2010
6|
A paradigm shift
• The Temel study split patients with newly diagnosed metastatic non-small cell lung cancer into two groups : one receiving standard oncological care, the other receiving standard oncological care with palliative care support
• The study hoped to find an increase in quality of life measurements in the palliative care arm, which it found
• The surprise finding was that the palliative care arm showed a statistically significant increase in median survival (11.6 months vs. 8.9 months), despite having less aggressive care in the final days of life
7| 8|
9|
WHO Definition of Palliative Care
• Palliative care is an approach that improves the quality of life of patients and their families facing the problems associated with life-threatening illness, through the prevention and relief of suffering by means of early identification and impeccable assessment and treatment of pain and other problems, physical, psychosocial and spiritual. Palliative care:
• provides relief from pain and other distressing symptoms
• affirms life and regards dying as a normal process;
• intends neither to hasten or postpone death;
• integrates the psychological and spiritual aspects of patient care;
• offers a support system to help patients live as actively as possible until death;
• offers a support system to help the family cope during the patients illness and in their own bereavement;
• uses a team approach to address the needs of patients and their families, including bereavement counseling, if indicated;
• will enhance quality of life, and may also positively influence the course of illness;
• is applicable early in the course of illness, in conjunction with other therapies that are intended to prolong life, such as chemotherapy or radiation therapy, and includes those investigations needed to better understand and manage distressing clinical complications.
10|
National Guidelines Regarding Palliative Care
• Growing number of guidelines from major cardiology societies, including the ACC Foundation, ISHLT, Heart Rhythm Society, and HF Society of America encouraging the use of palliative care into the care of patient with HF. Historically, these have focused on end-of-life decision making, especially with regard to device management
• More recently there has been an acknowledgement of the benefits of PC earlier in the disease trajectory, as well as involvement of PC in the decision making process.
• In 2012, the AHA issued a recommendation to refer to specialty palliative care for assistance with difficult decision making, symptom management in advanced disease, and caregiver support, emphasizing that “the use of palliative care services should not be considered equivalent to the withdrawal of disease modifying therapies.”
• In 2013, the ISHLT issued a recommendation that specialty palliative care consultation should be included in the treatment of end-stage HF during the evaluation phase for MCS
11|
LVADs and Palliative Care
• As of October, 2014, the Joint Commission (JCAHO) has mandated that institutions which perform destination VAD implantations must have a “palliative care representative on the core interdisciplinary team”
• Shortly after, the Center for Medicare and Medicaid Services (CMMS) mandated inclusion of palliative care specialists in the multi-disciplinary team caring for VAD recipients
12|
ELSO GUIDELINES FOR ECMO CENTERS
9. The following consultants should be available as needed. • Pediatric/adult neurology • Pediatric/adult nephrology • Pediatric/adult pulmonology • Pediatric/adult infectious disease • Occupational/physical therapist • Developmental/rehabilitation specialist • Speech therapy/feeding therapy specialist • Social Services/Palliative Care • Spiritual Support
13|
Current literature on palliative care in ECMO
• Scant research regarding palliative care in (adult) ECMO patients.
• One article from Columbia looked retrospectively at the number of ECMO patients who received palliative care consultations (48.2%) with an equal number consulted early (< 7 days of ECMO initiation) and late ( > 7 days).
• Nakagawa, Garan, Takeda, Takayama, Topkara, Yuzefpolskaya, Yuill, Lin, Colombo, Naka, Blinderman. J Pall Med. 2019 Apr 22(4): 432-436
• The remainder of the literature focuses primarily on the ethical issues surrounding ECMO, particularly discussing the concept of “futile care"
14|
• Case #1
• 64 year old male suffering massive MI, transferred from OSH, placed on ECMO emergently.
• During prolonged hospital admission, has a tumultuous course including PEA arrest, renal failure (placed on CVVH), GI bleed
• On day 34, patient develops AMS and is found to have a large hemorrhagic stroke
• Palliative care is consulted at this time to assist with goals of care
• Case #1B
• 64 year old male suffering massive MI, transferred from OSH, placed on ECMO emergently.
• During the first 72 hours, palliative care is consulted to support patient and family. After initial assessment, PC continues weekly visits and coordination with ECMO team
• During prolonged hospital admission, has a tumultuous course including PEA arrest, renal failure (placed on CVVH), GI bleed. On day 34, patient develops AMS and is found to have a large hemorrhagic stroke
15|
• Case #1 - Late involvement of palliative care
• “New face” or “another doctor”
• Difficult to achieve rapport/therapeutic alliance with family in short time frame, especially under stressful situations
• Palliative care team is not as familiar with the patient / family
• Case #1B – Early involvement of PC
• Allows for early introduction of the palliative care team in a less dire setting and “normalizes” the use of PC
• Allows for gradual rapport building with patient / family and more in depth conversations regarding their values
• Palliative care can assist with symptom management, including pain, anxiety, etc.
• Palliative care can provide family support through the entire illness and not simply at ”the end”
16|
Role of palliative care in supporting the ECMO team
• Numerous studies have shown the emotional toll caring for ECMO patients can have on the providers, particularly with the evolving concept of “moral distress” among staff
• Palliative care can assist with supporting staff, both by facilitating regular communications with the patient/family as well as leading communication training for the staff
• Palliative care can also assist with “debriefing sessions,” particularly after challenging cases
17|
In summary…
• Although there are no current firm guidelines, palliative care should be involved at the initiation of ECMO to maximize their supportive care for the patient and family during the entire hospital course and not simply at end-of-life situations
• Palliative care can also provide support to the members of the ECMO team, particularly in difficult cases / issues of “moral distress”

BEG FOR RESOURCES!!!
But really…..Do we beg??
We do…..we just do it in a formalized manner.
How do we get the resources we need and how do we determine what those resources are?
people, money, equipment, commitment

Start small and grow big
Identify what the goals are
Identify the resources
Become creative with the asks
5
Start with the structure that exists
Should we recreate the wheel??
How can you creatively utilize the resources you already have?
How can you get additional resources once identified?
6
Proving that the program is worth it
There must be a financial analysis
There must be buy in from administration.
Outcomes
Developing relationships with other hospitals
7
Build your team: What do you need?
Dedicated surgeon(s)
Cardiology partners
Nurse Practitioner support
Administrative support
Perfusion
ECMO specialist
8
The most important component of a successful program
Teamwork and Communication!!
9
How do we deal with multiple services that get involved?
Every team needs a quarterback
A central hub for information
The owner of the plan
10
Making sure the plan gets distributed
Meeting after meeting after meeting
Rounding after rounding after rounding
Communication, communication, communication
11
Debrief is crucial…..
Identify what worked
Identify what did not work
Identify areas of success
Identify areas of improvement
12
How do you build a referral base for ECMO??
Educate when to refer
Communicate with referring physician
Just say yes program
13
Follow up with the physicians
Regular follow up
Communication post discharge
May want to get creative with thank you options for referring physicians
14
Consistency is key…..

Preparation and Training Referral CriteriaIndications for V‐A ECMO
End organ hypoperfusion due to low cardiac output Cardiac index <2.2 L/min/m2 or SvO2 <60%
on two inotrpoes Rising lactate, worsening metabolic acidosis Hypotension requiring two or more of the
following: Norepinephrine > 0.2 mcg/kg/min Vasopressin > 0.04 units/min Epinephrine > 0.2 mcg/kg/min Dopamine >10 mcg/kg/min Dobutamine > 10 mcg/kg/min Unstable arrhythmias
Indications for V‐V ECMO
Acute hypoxic or hypercarbic respiratory failure On FiO2 100%, Peep > 15
Oxygen saturation < 88% PaO2 <60 mmHg PaCO2 >60 mmHg Plateau pressure > 30 cmH2O
Contraindications for ECMO Referral Acute intracranial hemorrhage CPR >60 minutes Contraindications to anticoagulation Advanced cancer End stage liver disease End stage kidney disease

ECMO CannulationTotal transports
Transport RequestReferring Hospital request comes through ECMO pager or transfer center to ECMO teamUCAN team is notified of pending transport Pending bed status, UCAN team updates ECMO transport team on mode of transportation and timing
Team Mobilization
• Team configuration• 2 UCAN crew members are always required on transport
• CV Surgeon• ECMO Specialist• Perfusionist
• PA
• Cannulation vs Pt already on ECMO
• **Plan B**
• UCAN team mobilizes to transport:
• Ground vs Air• Multiple ambulance
Pre Transport Planning (Report)• UCAN flight nurse report
• Updated report from referring RN (standardized report sheet)
• Request (Cannulation)• T&S, ABG• 3 units PRBCs• 5% albumin• 5,000 units heparin• +/‐ extra vasoactive drips to bedside
• Request (ECMO)• T&S, ABG• 2‐3 units PRBCs• 5% albumin• +/‐ extra vasoactive drips to bedside
Report: Request for ECMO Cannulation for respiratory failure/ARDS. ‐ Rapidly deteriorating patient with flu like symptoms
‐ On NC yesterday‐ Now Peep +18 with SpO2 80’s
Pre‐transport planning (Equipment)
• UCAN team• Transport equipment for monitoring, medication administration (IV pumps), ventilation
• ECMO team• Transport Cardiohelp• ECMO bag
Pre Transport (Communication)
• Team briefing/patient report• Plan of care• Aircraft/Ambulance briefing
Transport (En Route to Patient)
• Safety First• Critical phases of flight• Controlled airspace• Clock Reporting• 4 to go, 1 to say no• Cell phones
At bedside• Abbreviated team assessment
• Patient on UCAN monitor
• Prep for cannulation• Coordinated on pump/transfer and titration of drips
• Coordinated patient movement
Transport (En route with patient)
• Communication
• Safety First• Critical phases of flight• Controlled airspace• Clock Reporting• 4 to go, 1 to say no
Transfer of care
• Stable patient• Standardized Report
“I’M UCAN”• Team coordinated movement
Post Transport
• Team debrief• Charting
• ECMO Physician Note• ECMO Specialist Note
• Fax to 2‐1993
• Charting details• ECMO settings on arrival• Cardiohelp settings on initiation or change of pumps
• Q15 min if stable• Q5 min if unstable or with changes
Lessons learned: Each case is different
I can hear you….• First case• 19 year old (73kg)• Hx asthma
• Intubated • Vent: AC 16‐450‐18‐100%• Propofol 65 mcg/kg/min
• PRBCs x2, 500ml heparin• Decreased propofol to 50mcg/kg/m
• Levophed added
• After recovery • Pt remembers events!
Hi Friend!• Called to cannulate for VV‐ECMO
• Hypoxic events with SpO2 60’s• AC 28‐400‐12‐85%• EF 55‐60%• Lung transplant work up
• Arrive bedside• Patient has a room mate…
• Uneventful cannulation and transport
We don’t always have to cannulate• Called to referring hospital 60min away to cannulate
• 37yr (61kg)• Chest pain ‐> cath lab• Vasospasm LAD• Bedside ECHO 10% (day prior)• Impella
• Arrive bedside• Updated report last CO 6.4• Bedside ECHO – marked improvement in cardiac function
• Pt doesn’t currently need ECMO cannulation
They can cut over the circuit• 55yr (89kg)• 3V CABG• Progressive ARDS• A‐flutter ‐> amiodarone
• Placed on ECMO at referring• Referring to cut over to cardiohelp
• 2 perfusionists from referring• Dislodged cap with blood loss• Troubleshooting by ECMO specialist
• Recapped – uneventful transports
Plan for catastrophic events• Transport of patient on other ECMO device
• Circuit cracked• Direct to OR
• Pump Failure• Battery failure• Cracked circuit• Weather
• Mechanical issues with aircraft
