SMOKE

Smoke

the gaseous products of burning materials especially of organic originmade visible by the presence of

small particles of carbon

a suspension of particles in a gas

TOXIC TWINS

Toxic Twins

Carbon Monoxide (CO) Hydrogen Cyanide (HCN)

Carbon Monoxide(CO)

Properties

Colorless Odorless Tasteless Flammable Gas

Where does it come from?

Produced when carbonaceous materials are burned with insufficient oxygen.

Annual Stats Over 2,000 deaths Several hundred thousand

exposed 20-40% suffer health damage

Physiologic Effects 250 times the affinity for

hemoglobin Displaces O2

Leads to Hypoxia

Symptoms

Headache Lethargy/

Fatigue Nausea Dizziness Confusion Dyspnea

Palpitations Convulsions Paralysis LOC Coma Death

Hydrogen Cyanide(HCN)

Properties

Colorless Bitter Almond Odor Gas

Sources in Fire Products

Polyurethane Foam Synthetic Rubber Nylon Asphalt Wool Silk

Physiologic Effects Prohibits the cells from using

oxygen Respiratory Paralysis Cardiac Irregularities

Symptoms – Low Levels

Bitter almond odor

Burning taste Numb Throat Salivation Nausea/Vomiting

Anxiety Confusion Vertigo Ataxia Giddiness

Symptoms – Moderate Levels

Hyperpnea Dyspnea Tachypnea Short Inspiration Prolonged Expiration Tachycardia

Symptoms – High Levels

LOC Coma Protruding

eyeballs Pupils dilated Bradycardia Respiratory

Arrest

Arrhythmias Convulsion Hypotension Incontinence Paralysis Sweating

Toxic Twins

Carbon Monoxide Attacks the blood

Hydrogen Cyanide Attacks the cells

ASSESSMENT

1st Priority

Treat Life-ThreatsImmediately

TREATMENT

BLS Airway

Suction Airway Adjunct

Breathing High-flow O2

NRB or BVM

Circulation CPR

ALS

Advanced Airway Establish IV/IO

Large Bore

Treat for CN Poisoning

Confined space with smoke?

Soot around mouth/nose?Altered Mental Status?

Cyanokit Study

69 Patients73% Survived Of the 19 subjects who did not

survive, 13 were presented in cardiac arrest.

Blood Draw

Cyanokit may interfere with lab tests

If time allows, draw 2 vials of blood

Mechanism

Attaches to cyanide ion Allows cells to utilize O2

Excreted in urine

Contraindication

Hx of allergic reaction Safety not established in pediatrics

Safe even without cyanide exposure

Side Effects

Hypertension Red Discoloration

Precaution

Use a separate IV/IO line

Dosing

5g over 15 minutes

Preparation

Glass Bottle Mix 200 cc of NS Don’t Shake

Administration

IV/IO Mix with 200 cc Saline Leave box in place 15 minutes “Power Syringe”
