Could a simple arm cuff replace the need for an artery needle during surgery?
NCT ID NCT04506775
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study tested a wearable, non-invasive blood pressure monitor called ViTrack against the standard method of placing a small tube in the wrist artery. Researchers compared blood pressure readings from 30 surgery or ICU patients at 255 time points. The goal was to see if the cuff is accurate enough to replace the more invasive catheter.
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 the ViTrack device proves accurate, it could offer a less invasive way to continuously monitor blood pressure during surgery or in the ICU.
- What could go wrong
- This is a small, early-stage comparison study with only 30 participants. The device may not meet accuracy standards or could cause skin irritation.
