A flatter loop indicates decreased compliance (stiffer lungs, as seen in ARDS), while a steeper loop indicates higher compliance. Variable Parameters (.var)
The maximum pressure reached in the alveoli at the end of inspiration. Shapes.PalV.3.var
(alveolar pressure) is the driving force for airflow. It is determined by two primary variables: Elastic Recoil Pressure ( Pstcap P sub s t end-sub It is determined by two primary variables: Elastic
): The pressure in the space surrounding the lungs, influenced by respiratory muscle effort.The relationship is defined by the formula: as seen in ARDS)
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
Palv=Pst+Pplcap P sub a l v end-sub equals cap P sub s t end-sub plus cap P sub p l end-sub Pressure-Volume (PV) Loop Shapes
): The pressure generated by the lungs wanting to collapse inward. Pleural Pressure ( Pplcap P sub p l end-sub
