New study aims to set standards for diagnosing arm artery disease
NCT ID NCT05192707
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study measures oxygen pressure in the skin of the upper arm to help diagnose chronic limb ischemia, a condition where blood flow is severely reduced. Researchers will test 30 healthy volunteers and at least 30 patients with known arm artery disease to find normal values and a threshold for critical ischemia. The goal is to create standardized guidelines for using this non-invasive test in the upper limb.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Transcutaneous oxygen pressure (TcPO2) measurement
- What this could lead to
- If successful, this could establish standard normal values and diagnostic thresholds for upper limb ischemia, improving detection and treatment decisions.
- What could go wrong
- This is a small, early-stage study with only 39 participants, so results may not apply broadly. It focuses on measurement, not treatment, so direct patient benefit is limited.
