A Randomized Controlled Trial of High-Flow Nasal Oxygen (Optiflow) as Part of an Enhanced Recovery Program After Lung Resection Surgery.

Background: Patients undergoing thoracic surgery are at risk of postoperative pulmonary complications, which are associated with increased morbidity and mortality. High-flow nasal oxygen therapy delivers humidified, warmed positive airway pressure but has not been tested routinely after thoracic surgery.

Methods: We performed a randomized, controlled, blinded study.
