Occurs in VALVE configuration when
the tidal volume is measured below
20ml during three consecutive
breaths for PSV, CPAP, PA/C and P
SIMV modes.
Alarm activation occurs after three
consecutive breaths if the tidal
volume is less than 20 mL.
Occurs in LEAK configuration when
the LEAK level is not sufficient to
flush the CO 2 from patient
exhalation. The built-in LEAK in the
mask may be obstructed.
The built-in leak for the mask is not
sufficient for the settings.
Alarm activation occurs if conditions
remain for the maximum time
between:
• disconnection time and 60/R-
Rate in P A/C and V A/C mode
• disconnection time and (Apnea
time +2 sec) in CPAP and PSV
mode
• disconnection time and (60/R-
Rate + Insp time) in P SIMV and
V SIMV mode.
If the flow is greater than 130 lpm
during the inspiratory phase.
In V A/C and V SIMV modes, if
patient pressure is lower than Min
PIP.
In PSV, CPAP, P A/C modes
and P SIMV if patient pressure is
lower than (P Support +
PEEP) - 20% or (P Control + PEEP) -
20%.
Detection of a fault in the electrical
power supply system.
1. Electrical power supply to the
machine is interrupted with the I/O
switch when ventilation is in
progress
or
2. Battery fully discharged when it
was the only source of power to the
ventilator.
Consequence: ventilation stops
immediately. Ventilation restarts
immediately when the switch is
pressed in case 1 (above) or after
restoration of the AC or DC supply
in case 2 (above).
