Finger cuff could spot dangerous drops in blood pressure during surgery
NCT ID NCT07216573
First seen Jun 25, 2026 · Last updated Jul 09, 2026 · Updated 3 times
Summary
This study compares standard arm-cuff blood pressure checks to a new continuous monitor worn on the finger during outpatient surgery. Researchers want to see if the finger cuff catches low blood pressure episodes better than the usual method. About 188 adults having elective noncardiac surgery will take part.
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 show that continuous finger-cuff monitoring helps doctors catch dangerous low blood pressure more quickly during routine surgeries.
- What could go wrong
- This is an early-stage observational study with only 188 participants, so results may not apply to all patients or settings. The device is not yet proven to improve patient outcomes.

Inclusion Criteria: 1. Signed informed consent 2. Age ≥ 18 years 3. American Society of Anesthesiologists (ASA) Physical Status ≥ 2 4. Scheduled for elective noncardiac surgery with intermittent arterial blood pressure monitoring using oscillometric arm cuff Exclusion Criteria: 1. Patient who is known to be pregnant 2.
