and PRESSURE (max., mean or min.).
Indicator LEDs: POWER: green LED indicates power on.
SYSTEM FAIL: Indicates main processor
system fail.
TRIGGER BACK-UP: Indicates a machine
delivered breath if patient fails to trigger
ventilator during back-up time window.
MAX., MEAN, MIN.: indicates which value is
being displayed on the 7 segment pressure
display.
MUTE: Indicates that the mute function is
active.
Alarm LED’s LOW CPAP : warning of the pressure dropping
below the LOW CPAP alarm limit
CYCLE FAIL: warning that no breath has been
detected. Ventilator breath is below alarm
threshold.
HIGH: warning of the PIP alarm limit being
exceeded
BLOCK: warning of a block in the fresh gas
supply limb of patient circuit.
LEAK : warning of a leak in the fresh gas
supply limb of the patient circuit.
Driving Pressure Gauge:

pressures above PEEP)
Gauge range :0-60 cmH
