Could a smartwatch replace rectal thermometers in the ICU?
NCT ID NCT06942338
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study will check if a wristband called the CardioWatch 287-2 can accurately measure body temperature in 120 ICU patients. Currently, the most reliable method is a rectal probe, which is invasive and uncomfortable. The wristband uses skin temperature and heat flux to estimate core temperature. If it works well, it could offer a non-invasive, continuous way to monitor fever in hospital settings.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Corsano CardioWatch 287-2 (wearable wristband)
- What this could lead to
- If accurate, this wristband could replace invasive temperature monitoring in hospitals, making it easier and more comfortable for patients.
- What could go wrong
- This is a small, early-stage accuracy study, not a treatment trial. The wristband may not be as reliable as current methods, and results may not apply to all patients.
