Wearable device for prevention of postoperative and post-discharge hypoxemia: a randomized pilot trial.

The Oxalert system was well tolerated in both groups and enrollment was strong. Patients randomized to active Oxalert systems experienced half as many postoperative desaturation events while hospitalized, although the difference was not statistically significant in this small pilot trial. In contrast, the Oxalert system did not reduce post-discharge desaturation. A full trial of in-hospital desaturation alerts thus seems warranted. The trial was registered at ClincialTrial.gov (NCT04453722). This article is protected by copyright. All rights reserved.
