WebFigure 22.3.1 – Boyle’s Law: In a gas, pressure increases as volume decreases. Pulmonary ventilation is dependent on three types of pressure: atmospheric, intra-alveolar, and interpleural. Atmospheric pressure is the amount of force that is exerted by gases in the air surrounding any given surface, such as the body. WebPositive pressure ventilation can, however, increase pulmonary vascular resistance which can increase blood flow through an anatomic shunt thereby decreasing blood flow through the lungs and worsening hypoxemia.
