Heated humidified high-flow nasal cannula oxygen after thoracic surgery — A randomized prospective clinical pilot trial

Pulmonary complications were rare after thoracic surgery. Although HHFNC O₂ did not convey significant benefits, these results need to be interpreted with caution, as our study was likely underpowered to detect a reduction in pulmonary complications. High rates of patient-reported discomfort with HHFNC O₂ need to be considered in clinical practice and future trials.
