Continuous positive airway pressure (CPAP) is highly effective in treating obstructive sleep apnea (OSA). However, this treatment modality relies heavily on patient adherence, and poor adherence to the treatment limits its effectiveness in treating OSA. Strategies to augment adherence are needed in the management of OSA.

The smart watch and linked app provide various health information, including sleep, snoring or oxygen saturation during sleep, exercise, blood pressure, and electrocardiogram. The smart watch and linked app could potentially improve adherence to positive airway pressure (PAP) treatment.

This randomized controlled trial (RCT) aimed to examine whether the use of smart watch and app can increase PAP adherence in patients with OSA.
