Pressure Limit Control(LP 10 only) does not

end inspiration.

Classification In SIMV, patient must

breathe through the

circuit, humidifier and

then through the piston

intake valve unless one-

way valve teed in nearpatient wye.

Internal resistance is 1.0

cm H20/L/sec.

Oxygen is added between

the ventilator and thehumidifier or via reservoir

bag added to piston

intake valve for 40% or

more oxygen

concentrations.

Modes cont. Pressure Limited Mode (LP 6)

The High Pressure

Alarm/Limit control limits

pressure wi thoutan alarm

and does not end

inspiration. The set tidalvolume may notbe delivered

if inadequate inspiratory

time is set. If inspiratory

time too long will get System

Error Alarm. Airway pressure developed

during inspiration is

independent of alarm/limit

setting.

Modes cont. SIMV Mode

Mandatory breaths givenaccording to the Rate controland patient allowed tobreathe through ventilator orone-way valve, if added, forspontaneous breaths. If theSIMV rate is set < 6 BPM andthe patient fails to initiate anassisted SIMV breath within20 seconds, the apnea alarm

activates and the ventilatorswitches to Backupventilation at a rate of 10BPM.

LP 10 machine breaths canbe Pressure Limited.

Alarms Low Pressure/Apnea

Low pressure is the primarydisconnect alarm except whenrate set < 6 BPM. Apnea alarmactivates if no patient effortsensed within 20 seconds and

the rate is < 6 BPM. Automatically switches to 10

BPM at the same tidal volumeand inspiratory time. Alarmmust be manually reset.

Functional in all modes.

Alarms Low Power

alarms when batterypower drops to 10 volts.There is no alarm whenpower source switchesfrom internal battery to

AC. There is an alarmwhen power switchesfrom AC to internal andmust be reset.

High Pressure

Ends inspiration in A/Cand SIMV modes. Setsthe pressure limit whichdoes not end inspirationin Pressure Limited Modefor LP 6.

Indicators

Battery Test - shows charge level underneath

airway pressure.

Breathing effort - indicates assisted breaths. Power - indicates whether AC power or

battery charge, external battery, or internal

battery in use. Battery requires 2 hours of

charge for every 1 hour of use.

O2 Bleed in

Can bleed in oxygen between ventilator and

humidifier up to 40%. 40% and over must add

reservoir bag and oxygen to the back at thepiston intake filter.

Circuit

Circuit

Requires exhalation valve and proximal

airway pressure line. Clean circuit withsoapy water, rinse, and then soak in 1/3

cup vinegar per cup of water for 30

minutes every 24 hr.
