During inspiration the intrapleural pressure
WebAs inspiration continues, lung volume increases (moves toward the y-axis) and airflow increases (moves downward). The patient continues inhaling until they are at total lung capacity (or TLC). They then exhale as hard and as fast as they can, forcefully emptying the lung as quickly as possible. WebIntrapleural pressure is different from intrathoracic pressure. The thoracic cavity is the space that ... relationship between the intra-pulmonary pressure and intra-pleural …

WebDuring a normal tidal wave inspiration, intrapleural pressure starts somewhere around -5 (cm H 2 O) and becomes more negative to be close to -8 (cm H 2 O) at the end of inspiration. The amount of work that is done to expand the lung volume is equal to force times volume or the area shaded in green.
