5. Set PEEP Valve Pressure to the following values:
(5±1)cmH2O, (20±1)cmH2O, (50±1)cmH2O, (70±2)cmH2O, (90±2)cmH2O
6. Make sure that the deviation between the measured data of the PAW sensor, PEEP
pressure sensor and that of the anesthesia machine calibration device must not exceed 1
cmH2O or 2% of the measured value of the calibration device, whichever is greater.
Otherwise, perform pressure calibration again.
