Message
SAFETY VALVE Safety valve is open
OPEN
VENT INOP
Ventilator failure due to a recoverable or non-recoverable
condition. The safety valve opens, indicated by a SAFETY VALVE
message, and the patient is allowed to breathe room air. PEEP is
not maintained
LOSS, AIR Wall air drops below 18.0 psig (1.2 bar) and no functional
compressor is installed or the compressor output is insufficient to
meet instrument demand. Patient will continue to be ventilated by
O supply only.

and the %O
by the air supply only
LOSS, HELIOX The alarm is triggered if heliox is being used and the heliox gas
supply to the ventilator drops below 18.0 psig (1.2 bar). The
patient continues to be ventilated by the oxygen supply only.
LOSS, GAS All sources of gas fail; wall air, internal compressor (if installed)
SUPPLY and oxygen. The safety valve opens, indicated by a SAFETY
VALVE OPEN message, and the patient is allowed to breathe
room air. PEEP is not maintained.
NOT
The internal blended gas pressure is below 1 psi for greater than
VENTILATING about 12 seconds, indicating there is no ventilation occurring.
The safety valve should be open in this condition, as there is no
pressure to keep the safety valve closed. This alarm is only a
monitor of this pressure level and does not change the "state" of
the ventilator. The condition is recoverable if pressure is restored.
LOW P
The peak inspiratory pressure for a breath is less than the set

LOW P
HIGH P Peak inspiratory pressure is greater than the set HIGH P

Inspiration is terminated and the circuit pressure is allowed to
return to baseline pressure + 5 ± 1.5 cmH
breath is delivered.
EXT HIGH P Activates whenever the HIGH P
