5.12 Patient Pressure and Alarms
Set ventilatory controls to: MV/TV = 10L/1000ml
Freq = 10 BPM
Ratio = 1:1.0.
After several breaths, note the delivered peak pressure, the ventilator monitored peak and mean
pressures.
Reduce the pressure high alarm limit until a pressure high alarm just occurs and note the
control setting. Restore control to default.
Increase the pressure low alarm limit until a pressure low alarm just occurs and note the
control setting. Restore control to default.
5.13 Adult Pressure Limit
Set ventilatory controls to: MV/TV = 12L/1200ml
Freq = 12 BPM
Ratio = 1:2.0
Set pressure limit to 50 cm H
2
0 and note the delivered peak pressure after several breaths.
Verify the pressure high alarm activates for a short period as the ventilator pressure cycles
into expiration.
5.14 Apnoea
With the ventilator running normally, disconnect the lower (female) patient flow input just as
expiration starts and note the time when the apnoea alarm activates for 30 seconds.
5.15 Ventilator Cycling Alarm
With the ventilator set to 20 BPM, 12 (600 ml TV), disconnect the lower patient flow input as
before and note the time to when the pressure low alarm activates.
5.16 Flow and Waveform
Set ventilatory controls to: (Patient = C50)
TV = 1000ml, Freq = 25 BPM, Ratio = 1:2.0
After several breaths note delivered TV.
Exchange the adult bellows for a paediatric bellows and change the test lung to a 5C
compliance
