17.18 Pressure Calibration Verification
Note: The ventilator must be at working temperature with the metal
electronic unit top cover on and connected to air for 1 hour prior to
verification.
Connect the proximal airway line to the calibration analyser. Check the zero level
in CMV mode at the following settings:
BPM 5
Insp time 0.10 seconds
PEEP 0
PIP 0
Re-check zero level to be 0.25mbar ±0.05 mbar. If adjusted re-check 8LPM fresh
gas.
a) Check the CPAP pressure settings in CPAP mode at the following settings:
PIP 30 mbar
b) Check the pressure settings and wave shapes in CMV mode at the following
settings:
BPM 25
Insp time 1.5 seconds,
PEEP 0
Check list Item 18.
Warning: Re-charge the ventilator batteries for a minimum of 24 hours after
a full calibration procedure.
