Answer

Answer

Supplemental oxygen use should be guided by pulse oximetry. Patients should receive supplemental oxygen if their pulse oximetry reading or arterial blood gas measurement reveals that they are hypoxic (SaO 2 < 94%). The most common causes of hypoxia in the patient with acute stroke are partial airway obstruction, hypoventilation, atelectasis, or aspiration of stomach or oropharyngeal contents. [18, 19]
