Webpressure difference (or pressure drop) across the whole lung, including the airways and lung tissue (2–4), and is thus defined as the pressure at the airway opening (Pao) minus the pressure in the pleural space (Ppl), PL =Pao2Ppl (Figure 1, Table 1). The transpulmonary pressure can be partitioned into the pressure drop down the airway WebAug 18, 2024 · In aortic valve stenosis, the aortic valve opening is narrowed (top row). The narrowing requires increased pressure within the heart to pump blood across a smaller opening. Eventually this reduces … WebIt has been recommended that the optimal PEEP should be set above the critical closing or critical opening pressure of the airways. This can be deduced by the lower inflection point generated with static pressure-volume loops (Figure 49-19).
