(d) Adjust the inspiratory time stem for a 3 second (plus or minus 0.1
second) inspiratory pause.
(e) Rotate the inspiratory relief pressure stem clockwise to obtain a peak
inspiratory pressure of 80-82cmH20 (60mmHg).
(f) Apply Lubewick to the O-ring on the outside of the retention clip and
secure the control knob with the index clockwise to the 3 o'clock cam stop as shown in
Figure 2-7. Control knob position.
(g) Confirm a peak inspiratory pressure of 80 to 82cmH20 and then
rotate the control knob fully counterclockwise. Peak cycling pressure on the manometer
should fall between 8 to 14cmH2O.
(h) Use the procedures detailed in Table 2-10 to troubleshoot the
inspiratory-relief pressure (spoiler assembly).
Inspiratory lockout (compound-lockout cartridge).
(a) Turn the source gas off and use a 5/16-inch wrench to remove the
9-o'clock plug from the side of the inspiratory time-limit valve (refer to figure 2-2,
(b) Connect the inspiratory lockout test gauge (P/N 4454, 0 to 60psig
gauge with red tubing) into the same outlet port.
(c) Rotate the inspiratory time-limit stem (located above the reset
button) approximately 1/2 turn counterclockwise and then turn the source gas on. The
following should occur.
1 The Babybird ventilator cycles once, followed by an inspiratory
lockout (ventilator automatically switches to a continuous-flow system) which activates
an audible alarm.
