San Francisco, May 19 – A breakthrough in wearable health technology is poised to transform the diagnosis and management of obstructive sleep apnea (OSA), a common but often underdiagnosed sleep disorder. Researchers have unveiled a ring-shaped pulse oximeter, paired with a sophisticated software platform, that enables comfortable, continuous, and medically approved monitoring of sleep-related breathing disturbances.
Unlike traditional sleep studies, which require patients to spend nights in specialized clinics hooked up to numerous sensors, this innovative device allows for at-home monitoring over extended periods. Clinical trials have demonstrated high patient adherence, with 85% of participants exceeding recommended usage and some wearing the device for up to 44 nights. This extended data collection provides a more nuanced view of night-to-night variations in breathing, offering insights that single-night studies may miss.
Ketan Mehta, head of product and engineering for Connected Wearables at Apnimed, highlighted the device’s potential to change clinical practice. “One sleep specialist even reported that it may be better to collect one or two channels of data over 25 nights than 25 channels over one night, which is considered the gold standard with in-lab polysomnography,” Mehta explained. This approach could allow pulmonologists to routinely monitor patients’ OSA treatment responses, reducing the need for specialist referrals and making care more accessible.
The device distinguishes itself from popular consumer wearables like the Apple Watch and Oura ring, which can track sleep metrics but are not cleared for clinical diagnosis. In contrast, this new ring is FDA-cleared for medical use, bridging the gap between clinical-grade equipment and user-friendly consumer gadgets.
Technically, the ring leverages transmittance-based photoplethysmography, a method that enhances signal quality even in low blood flow conditions, making it particularly effective for overnight monitoring on the finger’s proximal phalanx. Unlike devices that only perform spot checks, this wearable captures continuous data throughout the night.
A companion smartphone app grants both patients and healthcare providers access to key health information, promoting transparency and shared decision-making. “This transparency empowers both parties to make informed decisions and facilitates more meaningful communication, enabling shared decision-making through digital medicine,” Mehta added.
Experts believe this technology could revolutionize sleep apnea care, making precise, routine monitoring possible outside of sleep labs and improving outcomes for millions of people affected by OSA and related conditions.
