This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.

Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.

Summary

This study tests a wearable patient monitor's ability to measure blood oxygen levels accurately. Healthy adults aged 18 to 40 will breathe air with reduced oxygen to simulate low-oxygen conditions. The monitor's readings are compared to a standard reference device. The goal is to improve wireless monitoring of breathing and circulation for patients recovering from surgery.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If successful, this could help refine a wireless patient monitor that tracks breathing and circulation after surgery.
What could go wrong
This is a small, early-stage technical test in healthy volunteers, not a treatment trial. The device may not perform as expected in real patients.

This is an AI summary of the original study and may miss details. Read our disclaimer.
