Experiences of Patients With Chronic Obstructive Pulmonary Disease Using the Apple Watch Series 6 Versus the...

Amid the rise in mobile health, the Apple Watch now has the capability to measure peripheral blood oxygen saturation (SpO₂). Although the company indicated that the Watch is not a medical device, evidence suggests that SpO₂ measurements among patients with chronic obstructive pulmonary disease (COPD) are accurate in controlled settings. Yet, to our knowledge, the SpO₂ function has not been validated for patients with COPD in naturalistic settings.

This qualitative study explored the experiences of patients with COPD using the Apple Watch Series 6 versus a traditional finger pulse oximeter for home SpO₂ self-monitoring.

We conducted individual semistructured interviews with 8 female and 2 male participants with moderate to severe COPD, and transcripts were qualitatively analyzed. All received a watch to monitor their SpO₂ for 5 months.

Due to respiratory distress, the watch was unable to collect reliable SpO₂ measurements, as it requires the patient to remain in a stable position. However, despite the physical limitations and lack of reliable SpO₂ values, participants expressed a preference toward the watch. Moreover, participants' health needs and their unique accessibility experiences influenced which device was more appropriate for self-monitoring purposes. Overall, all shared the perceived importance of prioritizing their physical COPD symptoms over device selection to manage their disease.

Differing results between participant preferences and smartwatch limitations warrant further investigation into the reliability and accuracy of the SpO₂ function of the watch and the balance among self-management, medical judgment, and dependence on self-monitoring technology.
