Quizplus · Accepted Answer

Breathing 100% oxygen for 24 hours or longer can lead to several physiological changes due to oxygen toxicity. These include decreased diffusion capacity of the lung for carbon monoxide (DLCO) due to damage to the alveolar-capillary membrane, decreased lung compliance (CS) as the lungs become stiffer, increased alveolar-arterial oxygen gradient (PAO2 - PaO2) due to ventilation-perfusion mismatch, and decreased vital capacity (VC) as a result of reduced lung compliance and potential development of pulmonary edema.
