16.4 CMV Set-up
Step 1. From the
Mode Select panel
select CMV.
Step 2. Default parameters in the preview mode:
BPM 30
Ti 0.4 sec.
PEEP 2 mbar
PIP 10 mbar
O
2
% As per prescription
Step 3. Press the Confirm button to enter
the CMV mode. The ventilator will now start to
ventilate at the set parameters.
16.4.1 Actions after connection to patient in
CMV
Step 4. The High and Low Pressure Alarm
thresholds auto track the pressure waveform by 5
mbar. The alarm thresholds can be adjusted if
required. The thresholds are found in the pressure
waveform window.
Step 5. The Cycle Fail Alarm threshold auto tracks
the PIP setting. The alarm threshold can be
adjusted if required. The threshold is found in the
pressure waveform window.
Step 6. Set the High and Low Tidal Volume
thresholds. These thresholds are found in the Tidal
Volume waveform window. (This waveform will not
appear when operating without a flow sensor).
16.4.2 Interactive and limiting controls in CMV
The user needs to be aware that the following
controls interact.
The BPM and Insp time controls interact. Increasing
the number of breaths per minute can decrease the
inspiratory time. Increasing the Insp time can
decrease the number of breaths per minute. This
occurs when the number of breaths per minute
cannot be achieved with the set inspiratory time or
the set inspiratory time cannot be achieved with the
set number of breaths per minute.
The PEEP control interacts with the PIP control.
When increasing the PEEP pressure, the PIP
pressure will track accordingly if initially below the
starting PEEP level.
The PIP control is limited by the PEEP. The user
cannot decrease the PIP level below the PEEP
level. The PEEP parameter control displays a
warning stating the limiting pressure.
The ventilator is now ready to be
connected to the patient under user
supervision. Prior to and after
connection, it is the user’s
responsibility to adjust and monitor
the ventilation parameters to suit the
patient’s medical condition.
