WebIntroduction: Inappropriate mechanical ventilation in patients with acute respiratory distress syndrome can lead to ventilator induced lung injury (VILI) and increase the morbidity and mortality. Reopening collapsed lung units may significantly reduce VILI, but the mechanisms governing lung recruitment are unclear. 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.
