Question Answer
upright sittingvertical lung height and AP expansion greatest; mechanical compression of lungs is minimal; most comfortable position for patients with pulmonary complications
pronecauses a decrease in AP expansion of abdomen; lateral diameter increased as compared to upright; created FRC as compared to sitting
positioning of patients with pathology in superior and posterior lung segments of lower lobes have increased oxygenation if placed in ? prone
supinelateral diameter increased as compared to upright; diaphragm moves toward head resulting in increased abdominal pressure; FRC is less than in upright or prone
side-lyingin conditions like atelectasis or pneumonia, affected side is up to improve ventilation-perfusion ratio
