Arterial blood gas analysis reveals a low PaO₂ despite increases in supplemental oxygen administration (refractory hypoxemia).Initially,the PaCO₂ is low as a result of hyperventilation,but eventually the PaCO₂ increases as the patient fatigues.The pH is high initially but decreases as respiratory acidosis develops.
