The trans pulmonary pressure is
Transpulmonary pressure is the difference between the alveolar pressure and the intrapleural pressure in the pleural cavity. During human ventilation, air flows because of pressure gradients. Ptp = Palv – Pip. Where Ptp is transpulmonary pressure, Palv is alveolar pressure, and Pip is intrapleural pressure. See more Since atmospheric pressure is relatively constant, pressure in the lungs must be higher or lower than atmospheric pressure for air to flow between the atmosphere and the alveoli. If 'transpulmonary pressure' = 0 (alveolar … See more Transpulmonary pressure can be measured by placing pressure transducers. The alveolar pressure is estimated by measuring the pressure in the airways while holding one's breath. The intrapleural pressure is estimated by measuring the pressure inside a … See more WebMay 8, 2024 · National Center for Biotechnology Information

WebThus, pleural pressure ends up being the main distending pressure which maintains patency of the alveoli. The implication of the difference between apical and basal pressure is that the transpulmonary pressure in the apical alveoli is going to be substantially different from the transpulmonary pressure in the basal alveoli. This has meaning.
