“…Prophylactic application of positive pressure after gastroplasty has shown improvement of gas exchange and lung function when compared to the use of oxygen therapy alone 32 . The results of Pessoa et al 31 corroborate these studies by showing a comparison of the use of BiPAP with oxygen therapy in the recovery room. Although the authors did not demonstrate a significant difference in the prevalence of atelectasis, they found that the group that carried out NPPV evolved with better oxygenation, probably by increasing the FRC promoted by positive pressure without compromising the integrity of the gastrojejunal anastomosis.…”

“…Ten studies investigated prophylactic CPAP (28–34, 37 40, 43), six studies utilized NIV (35, 36, 39, 41, 42, 44), and one study (38) compared both NIV and CPAP with standard care. Eleven studies implemented continuous therapy (28, 31, 33–38, 40, 42, 43), and six studies used intermittent (29, 30, 32, 39, 41, 44).…”

In most studies, NIV or CPAP or both were reported to be initiated on the same day as surgery, although two studies commenced therapy on postoperative day one (32, 39).…”

“…In recent years, this modality has emerged as a useful approach to improve oxygenation in OSA patients who develop hypoxaemia in the immediate post-operative period of bariatric surgery. Most of the currently available literature has reported favourable outcomes from the usage of NIV in post-operative bariatric surgery (1, 3, 4).…”
