Shapes.palv.3.var -

Indicates lung overdistension , where increasing pressure results in little additional volume gain, signaling a need to reduce tidal volume.

Based on the notation , this content likely refers to variables associated with Pressure-Volume (PV) loops and alveolar pressure ( Palvcap P sub a l v end-sub Shapes.PalV.3.var

The difference between the inflation and deflation curves. A wide loop can suggest recruitment of alveoli or significant energy dissipation. Indicates lung overdistension
