To perform the test:
• establish a closed patient airway circuit.
• increment the pressure in the airway circuit.
• observe the output of the airway pressure transducer.
• note that the "pressure limit circuit" trips at approximately 109 cmH
1. Remove the ABS breathing system from the machine.
2. Remove the Exhalation Valve.
3. Remove the Vent Engine cover.
4. Separate the Circuit Module from the ABS Bellows Module.
5. Install the Circuit Module only.
6. Plug the Drive Port (A) on the Vent Engine interface valve.
7. Attach a patient circuit tube to the Calibrated Flow Orifice test tool.
8. Insert the Calibrated Flow Orifice into the Manifold (pilot) Port (B).
9. Connect the open end of the patient circuit tube to the inspiratory flow
patient connection (C).
