3. RELIEF VALVE
CYCLE/CPAP switch to CPAP
PIP full CCW
PEEP PRESSURE full CW
INSPIRATORY TIME .5 sec
EXPIRATORY TIME 1.0 sec
Occlude patient circuit exhalation valve exhaust port and slowly increase flow to
6 LPM. Manometer should indicate between 65 and 80 cm pressure. Check
ADJUSTABLE RELIEF VALVE at patient outlet at rear of unit if pressure is less
than 65 cm. Increase flow to a total of 12 LPM and verify pressure is between
65 and 80 cm. Reduce flow to 4 LPM. With exhalation valve exhaust port open
to atmosphere, switch CYCLE/CPAP to CYCLE. Manometer should reach a
minimum of 65 cm during inspiratory phase.
4. MAXIMUM PRESSURE
CYCLE/CPAP switch to CYCLE
PIP full CCW
PEEP PRESSURE full CW
TOTAL FLOW of 6 LPM
INSPIRATORY TIME 2 sec
EXPIRATORY TIME 1 sec
Manometer should read 70 ±5 cm during inspiratory. Turn PIP knob clockwise
until pressure decreases. Continue turning to OFF position (knob reference line
at 6 o'clock position and resistance is felt). Manometer fluctuation should be no
more than 1 cm. CAUTION: DO NOT FORCE VALVE.
5. PEEP PRESSURE
CYCLE/CPAP switch to CYCLE
PIP full CCW
PEEP PRESSURE full CCW
TOTAL FLOW of 6 LPM
INSPIRATORY TIME .5 sec
EXPIRATORY TIME 1.0 sec
Manometer should read 18 ±3 cm during expiratory. Turn PEEP PRESSURE
knob clockwise until PEEP PRESSURE decreases. Continue turning to OFF
position (knob reference line at 6 o'clock and resistance is felt). During
expiratory, manometer should read less than 1 cm above manometer zero
reading. CAUTION: DO NOT FORCE VALVE.
