SITUATION: You are calibrating a Babybird pediatric ventilator. Use this situation to
answer questions 3 through 5.
You are calibrating the flow system and have not been able to obtain acceptable
flow rates from the ventilator. You have determined the problem is not the
calibration regulator, leaks in the tubing, misconnections of the green and white
tubing, nor the calibration gauge. What should you examine next?
a. Calibration regulator.
b. Expiratory flow gradient valve.
The bypass valve.
d. The outflow valve.
You are calibrating the expiratory-flow gradient with the selector switch in
spontaneous breathing and the outflow valve fully open. You adjust the flow to
10 lpm. What should the test manometer read?
a. Minus 10cmH2O.
b. Plus 2 to 4cmH2O.
The 5 to 7 o'clock position.
d. Twelve to 15psig.
To calibrate the inspiratory-relief pressure, you check for a single CAM stop at
which of the following positions?
a. 3 o'clock.
b. 6 o'clock.
d. 12 o'clock.
