What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

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.

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

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. Patient with existing or planned arterial pressure catheter 3. Patient in whom systolic arterial pressure differs by more than 20 mmHg between the right and left arms 4. Inability to place oscillometric cuff on the subject's upper extremity 5. Extreme contraction of the smooth muscle in the arteries and arterioles of the lower arm and hand, such as may be present in patients with Raynaud's disease 6. Finger or hand deformity that prevents proper placement of finger cuff by visual inspection 7. Inability to place finger cuffs due to subject anatomy, condition, or obstructive paraphernalia (such as false nails)
