c. Controlled Intermittent Mandatory Ventilation.
Turn the rotary selector switch to CONTROLLED IMV.
Turn the inspiratory relief pressure control to the fully clockwise position.
Turn the inspiratory time control to the fully clockwise position.
Turn the expiratory time control to the midpoint of its travel.
(5) Observe the PAP gauge. Inspiration should last 1.5 to 2.5 seconds. The
PAP gauge should read at least 60cmH2O. Expiration should last 1 to 2 seconds. The
PAP gauge should fall to the level established by the red arm on the outflow valve.
(6) Turn the expiratory-flow gradient counterclockwise. Negative pressure
should be apparent in expiration. Disconnect the red expiratory-flow line from the
negative (expiratory) venturi. Verify expiratory flow is present only during expiration.
(7) Turn the inspiratory-time-limit control counterclockwise until the alarm
sounds. After the alarm sounds, rotate the inspiratory time-limit control clockwise and
then push the reset button. Pushing the reset button should shut off the alarm.
CALIBRATE THE VENTILATOR
Now that you have learned how to perform the operational checkout of the
system, use the following procedures to calibrate the Babybird portable ventilator.
Complete the steps in the sequence presented in this lesson to obtain the calibration
parameters required. If the required parameters cannot be met, refer to the
troubleshooting procedures at the end of each system.
a. Equipment and Tools Required. You will need special items to calibrate the
Babybird ventilator. These special items may be obtained from Bird Corporation under
the following part numbers.
P/N 370--Mounting bracket.
P/N 4418--Flow test device.
P/N 4454--Inspiratory lockout test gauge.
P/N 5907--Babybird breathing assembly.
