John, does it seem to be unreliable but consistent? Meaning, do you feel it could be useful to spot trends?

I didn’t think it really helped. My BP varies quite a bit depending upon alcohol consumption in any event.

Summary: A Korean researcher is using a cuff-less wearable device, Sky Labs’ CART BP pro, to noninvasively monitor blood pressure during sleep to better understand the link between sleep apnea and cardiovascular risk.

Key Takeaways:

  • CART BP pro allows for high-frequency nighttime blood pressure measurements (e.g., every 5 minutes).
  • The cuff-less ring provides real-world cardiovascular insights that could support long-term patient monitoring and risk prediction.
  • It is already in use at over 1,300 hospitals in South Korea and is reimbursed by national health insurance, enhancing its accessibility.

A research presentation by Jin Oh Na, a professor at Korea University Guro Hospital Cardiovascular Center, introduced the application of CART (Cardio Tracker) BP pro, a cuff-less ring, in exploring the relationship between sleep and cardiovascular patterns, offering an opportunity to gain deeper insights into cardiovascular risks during sleep.

With the CART BP pro, made by South Korea-based startup Sky Labs, researchers can gather uninterrupted blood pressure data, offering an opportunity to better understand cardiovascular patterns during sleep.

Na made the research presentation, “Sleep and Cardiovascular Health: Why It Matters,” at the 2025 Annual Spring Scientific Conference of the Korean Society of Cardiology. Na’s upcoming research will explore the correlation between sleep apnea and cardiovascular risks using CART BP pro to measure blood pressure noninvasively during sleep.

Yes, I’ve been following the developments with this device. It would be awesome if it was reliable. But I’m wondering about the accuracy.

It’s great and tells me that you are in good health. I measure my BP several times a day, every day :frowning: which is annoying. Would love to have a wearable to do it instead. Agree on Apple Watch - I love mine as well and it measures everything I need.
