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

Prophylactic high-flow nasal oxygen therapy, when incorporated into an enhanced recovery program, did not improve 6-minute walk test results but was associated with reduced length of hospital stay and improved satisfaction after lung resection, compared with standard oxygen. This finding has implications for reduced costs and better service provision, and a multicenter trial powered for length of stay is required.
