Figure 8-18: Setting Alarm Limits That Are Not Currently Active

Selecting Waveforms (VCV only)

Two inspiratory flow waveforms for mandatory VCV breaths are available:
descending ramp and square wave (Figure 8-19). The selected waveform is
highlighted and defines the inspiratory flow for all mandatory VCV breaths,
whether they are initiated by the patient, the ventilator, or the operator. The
waveform selection is not applicable to PCV or NPPV.

NOTE:

Any of the changes made in the screen shown in Figure 8-18, do
not take effect until the operator switches to the new ventilation
breath type (in this case Pressure Control).

Grayed out buttons indicate that the alarm limits are not active
