4.4.4.2 Waveforms
The following figures show the Paw waveform and flow waveform in the 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.
