The difference between the inflation and deflation curves. A wide loop can suggest recruitment of alveoli or significant energy dissipation.
A flatter loop indicates decreased compliance (stiffer lungs, as seen in ARDS), while a steeper loop indicates higher compliance. Variable Parameters (.var) Shapes.PalV.3.var
For clinical practice, these waveforms are monitored using Ventilator Waveform Analysis tools to ensure patient-ventilator synchrony and protect lung health. VENTILATOR WAVEFORM ANALYSIS The difference between the inflation and deflation curves

Indicates lung overdistension , where increasing pressure results in little additional volume gain, signaling a need to reduce tidal volume.
The maximum pressure reached in the alveoli at the end of inspiration.
