WebA PaO 2 less than 55 mm Hg while breathing room air is considered severe and an indication for chronic 24-hour supplemental oxygen therapy. Milder degree of hypoxemia can be identified by comparing a PaO 2 with a predicted value for age. A simple estimate of a normal predicted PaO 2 is 105 – age (yr).
