A flatter loop indicates decreased compliance (stiffer lungs, as seen in ARDS), while a steeper loop indicates higher compliance. Variable Parameters (.var)
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 pressure generated by the lungs wanting to collapse inward. Pleural Pressure ( Pplcap P sub p l end-sub as seen in ARDS)
The difference between the inflation and deflation curves. A wide loop can suggest recruitment of alveoli or significant energy dissipation. Shapes.PalV.3.var
