Modes on LP 6 Plus and LP 10 Standby A/C: pressure limited or
not (LP 10)
SIMV: machine breathspress limited or not (LP10)
Pressure Cycle Set VT I.T. controls flowrate
Hi pressure alarmsetting endsinspiration butwithout audible
alarm. Airwaypressure isindependent of HPalarm setting duringinspiration.
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.

Controls Vt = 100 - 2200 ml Rate = 1 - 38 BPM
Inspiratory Time = .5 - 5.5sec
Sensitivity -10 to +10 cm H20
High Pressure Alarm Limit25 to 100 cm H20
Internal pressure relief at100 cm H20.

Inspiratory time If the inspiratory time
is set too long, asystem error alarmwill be activated.Otherwise, inspiratorytime essentiallydetermines the flow
rate of the set tidalvolume.

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.
