5. Adjust the pressure by using the syringe so that the pressure test equipment displays (5±1)
cmH2O, (20±1) cmH2O, (50±1) cmH2O, (70±2) cmH2O, and (90±2) cmH2O in sequence.
6. Verify that the deviation between the measured value of the PAW sensor displayed on the
machine and that of the pressure test equipment does not exceed 1 cmH2O or 2% of the
measured value of the calibration device, whichever is greater. Otherwise, perform pressure
calibration again.
