4. Set Hz at a range of 5 to 6 initially.
a. You may decrease the Hz if you cannot control the PaCO
of approximately 90 cmH
b. Decrease the Hz by 1 Hz at a time every 30 minutes until you reach a level of 3 Hz.
5. Set IT % at 33%.
You may increase this value up to 50% if you are unable to ventilate by
increasing the amplitude or by first decreasing the frequency.
Caution!
Using flows higher than 40 LPM may increase the risk of increasing
PaCO
due to decreasing the effectiveness of the active exhalation.

6. For severe hypercapnea with pH > 7.2, consider decreasing the endotracheal
tube cuff inflation to produce a leak.
a. Reduce the inflation of the cuff until you see a drop in the mP
5 cmH
O. Readjust the bias flow to correct the mP

b. Rule out obstruction in endotracheal tube with bronchoscopy.
