Phone app could boost lung recovery after surgery

This pilot study tested whether a smartphone-based program could help high-risk patients recover their breathing after lung surgery. Fifty-eight adults who had lung resection and were either older or had reduced lung function were split into two groups: one used a smartphone app for guided breathing exercises with remote support, and the other did the same exercises at home without supervision. The goal was to see if the app-based approach was feasible and improved walking ability and lung function over six weeks.
