Test setup
(Aespire machine)
1. Remove the ABS breathing system from the machine.
2. Remove the Exhalation Valve.
3. Separate the Bellows Module from the Circuit Module.
4. Install the Circuit Module only.
5. Set the Bag/Vent switch to Vent.
6. Attach a patient circuit tube to the Calibrated Flow Orifice test tool.
Note: The Calibrated Flow Orifice for the Aespire has the same orifice size
as the Calibrated Flow Orifice for the Aestiva; however, the Aestiva orifice
has a larger outside dimension that does not fit through the Vent Engine
cover plate. To use the Aestiva orifice with an Aespire machine, you must
remove the cover plate to access the manifold port.
7. Insert the Calibrated Flow Orifice into the manifold (PEEP) port.
8. Connect the open end of the patient circuit tube to the inspiratory flow
patient connection.
Test Procedure
1. Select “Start Test Pressure Limit Circuit” to start the test.
If the “Test Pressure Limit Circuit” trip point is approximately 109 cm H
2
O,
the test passes.
