female Luer fitting on the side of the ventilator. Decrease and maintain the vacuum until
a value in the range of 10 to 150 is displayed in the Tidal Volume window. If necessary,
add a large amount of compliance, such as a test lung, to the calibration syringe
assembly, this will significantly stabilize the readings during this step.
During this step, any value in the range of 10 to 150 displayed in the Tidal Volume
window is equally acceptable, but it is very important that the value displayed in the
Tidal Volume window is stable when pressing Select.
Alternatively, it is also acceptable to apply a small positive pressure to the ventilator low
pressure fitting to fulfill this step.
