In postoperative patients, [60]  note the following:

  • Postoperative hypoxemia related to atelectasis or pulmonary edema

  • Occurrence following multiple types of surgery (eg, lung, cardiac, abdominal) [61, 62, 63]

  • Randomized trials with postoperative continuous positive airway pressure (CPAP) demonstrate benefit

  • Applied as prophylactic support or with development of hypoxemia

  • Benefit noted with level CPAP levels in 7.5- to 10-cm water range

  • Lower intubation rates, days in ICU, and pneumonia

  • High-flow nasal cannula oxygen option (50 L/min and FiO2 = 0.50) may be comparable to noninvasive ventilation [33]
