Answer

Answer

Pulse oximetry on room air should be measured in all patients. The oxygen saturation should be measured both at rest and with exertion. If any hypoxemia is found (O2 saturation < 90%), then an arterial blood gas (ABG) level should be obtained to evaluate the need for possible adjunctive corticosteroids.
