Setup

After connecting circuit, power ON with switch located on back panel. Unit goes through self-test and requires calibration of flow and O2 sensor. Flow and O2 sensor will then require calibration at the same time every day. Flow calibration takes less than 20 seconds.

Check-out tests

  1. Test for leaks
    • Press CPAP
    • Set PIP limit to 80
    • Press Reset when asked if want PIP > 40 cm H20
    • Set Insp Flow to 2 LPM
    • Press and hold Manual Inspiration - Pressure bargraph goes to 80 cm H2O
  2. Check airway pressure
    • Press CMV
    • PIP limit to 20
    • Insp Flow to 10 LPM (pg 41 in Babylog Manual says 4 LPM but may not be enough)
    • IT to 0.4
    • ET to 0.6
    • PEEP/CPAP to 0 (pg 41 in Babylog Manual says 2.5)
    • Pressure bargraph goes up to 20 cm H2O and down to zero (or 2.5)
    • Set PEEP/CPAP to 10
    • Pressure bargraph goes to 20 and down to 10 cm H2O

Settings

  1. Select mode A/C (Pressure and flow waveforms of pressure limited breaths similar to pressure controlled waveforms), SIMV, or CPAP. Can turn flow trigger OFF or ON under special Functions.
  2. Want to keep tidal volume between 4 and 7 ml/kg
  3. IT = .4 - .5 and
  4. ET = .8 - 1 sec will give a Rate of 40 - 50 BPM
  5. PIP limit/CPAP of 20/4
  6. Flowrates 6 - 8 LPM

After connecting ventilator to baby and checking that chest rises, go into List and view Setting values to refine ventilator settings to optimize flow waveform.

 1. Reset minute ventilation alarms by pressing +/- 30%

2. Check that there is not a space between end of inspiration and beginning of exhalation using the flow/time graphic

3. Check that there is no air-trapping using flow/time graphic

4. Pressure limiting inspiration allows user to increase PIP Limit setting to increase tidal volume. However, if PIP Limit is increased and peak inspiratory pressure (PIP) does not increase to equal new PIP Limit setting, then increase the set Flowrate until peak inspiratory pressure is being limited again.

5. When pressure limiting ventilation, an increase in the PEEP/CPAP level will decrease the tidal volume if the PIP Limit is not increased by the same amount as well.
