WebPulmonary ventilation is the act of breathing, which can be described as the movement of air into and out of the lungs. The major mechanisms that drive pulmonary ventilation are atmospheric pressure (P atm); the air pressure within the alveoli, called intra-alveolar pressure (P alv); and the pressure within the pleural cavity, called intrapleural pressure …

WebNov 1, 2014 · Introduction. The diffusion of gases brings the partial pressures of O 2 and CO 2 in blood and alveolar gas to an equilibrium at the pulmonary blood-gas barrier. Alveolar P CO 2 (P ACO 2) depends on the balance between the amount of CO 2 being added by pulmonary blood and the amount being eliminated by alveolar ventilation (V̇ A).In … WebPulmonary ventilation is commonly referred to as breathing. It is the process of air flowing into the lungs during inspiration ( inhalation) and out of the lungs during expiration ( …
WebPulmonary compliance, a measure of the lung expandability, is important in ideal respiratory system function. It refers to the ability of the lungs to stretch and expand. Lung compliance can be calculated by dividing volume by pressure (C = V/P). Two factors affecting lung compliance are elasticity from the elastin in connective tissue, and ...
