Paw insp or Paw exp > 3 cmH2O when
bias flow set to 3 l/min air or O2 (if Air
not available) and exhalation valve set

Non-silencable
Audible in Standby and
Monitoring states.
When placed in Standby state
either by the user or after
power up, the ventilator will
maintain a bias flow so as to
detect if a patient has been
attached to the circuit. This
functionality alerts for an
inadvertent attachment of the
patient without the user
actuating ventilation. The
Standby menu shall be
displayed with the highlight on
Start Ventilation when alarm is
initially activated.
• Was patient connected during standby state? If yes, this is a user error. If no:
• Remove all tube connections from vent. If alarm persists, check exhalation pressure port and exhalation
valve housing.
• Calibrate Flow control valves.
• Calibrate airway pressure transducers.
• Using the Service App and occluded circuit, set 3 l/min flow, and set 6 cmH20 on exh. Valve. Ensure both
Insp and Exp pressure sensors read 6 ±3 cmH20. Open circuit and verify pressure is < 2 cmH20.
• Check/replace zero valves.
• Replace appropriate pressure sensor board.
• Replace appropriate flow control valve.
Paux high Paux High Low
Paux > 100 cmH2O De-energize Paux purge valve
(if purge valve is energized)
until alarm condition clears.
• Verify Paux port (and any tubing that is connected to Paux port) is not occluded when purge valve is energized
(purge is turned ON).
• Zero Paux pressure sensor.
• Use the Service App to calibrate the Paux pressure sensor (Section 5.2.8).
• Interchange Paux and Pexp connections. If Paux high alarm stops, replace Paux sensor.
• If Paux High alarm continues, replace VCB.

(Purge is turned ON).
• Zero Paux pressure sensor.
• Check/replace harness.
• Interchange Paux and Pexp connections. If Paux alarm stops, replace Paux sensor.
• If Paux alarm continues, replace VCB
