4.5.6 Inspiratory
Flow Valve
The Inspiratory Flow Valve Calibration should be performed:
• when the machine is first put into service.
• at prescribed, planned maintenance intervals.
• after the pneumatic vent engine has been serviced.
Note The Paw Zero and Paw Gain must be calibrated before the
Inspiratory Valve Calibration. Select the Calibration Coefficient
menu, set the calibration coefficient as marked on the calibration
orifice before the Inspiratory Valve Calibration.
Calibration Setup 1. Remove the bellows assembly, then connect the calibration
fixture (A) to the drive gas outlet.
2. Connect the large port of flow sensor (B) to the calibration fixture.
3. Connect the calibration pipe (C) to the small port of flow sensor.
4. Connect the calibration orifice (D) to the calibration pipe.
5. Connect the calibration fitting (E) to the inspiratory flow port.
6. Connect the tubing from calibration pipe to the calibration fitting.
Ensure that the test tubing is leak free and the flow sensor tubes are
connected.
