The paw and flow waveforms in PCV mode
Generally, in the PCV mode, the Paw waveform rises sharply during inspiration and stays at
the plateau for a relatively long time without peak. The flow waveform declines in the same
period.
In the PCV mode, tidal volume is measured instead of preset.
6.5.2.2 Start PCV Mode
1. Push the [
Modes
] button to open the [
Modes
] menu.
2. Push [
PCV
] in the [
Modes
] menu, then the [
controls
] menu for PCV mode is opened.
3. Adjust appropriately parameter settings for the patient and then confirm the settings so as to
start PCV mode.
6.5.2.3 Parameter Setup Area in PCV Mode
When PCV mode is confirmed, Key parameters is automatically switched over to the parameter
setup area in this mode. It is convenient to monitor and set.
The following figure shows all related parameters to be set in PCV mode.

2. [I:E]:
Ratio of inspiratory time to expiratory time
3. [Rate]:
Breath rate
4.
[PEEP]:
