4. Run the ventilator in volume control with the sensor at the patient using
the following settings:
BPM 12
Volume 500 ml
I:E 1:2.0
Pressure Limit 50
PEEP OFF
5. Once the volume has stabilized, verify that the measured volume on the
fl ow analyzer attached to the inspiratory port is 450 - 550 ml. The Vte and
Vti readings on the ventilator (displayed in the red box) should represent
the measured delivered volume +/- 5ml. If an adjustment is necessary,
the gain factor can be adjusted for both Vte and Vti to align the ventilators
displayed measured volume with the actual measured delivered volume.
