About

Retrospective analysis of transcutanesou oximetry (Tcpo2) recording for patients referred with suspected critical limb ischemia searching for specific changes in TcpO2 patterns.

Full description

• Patients had Tcpo2 recording at the suspected limb and chest level at rest in the lying position.
• Provocative tests (leg elevation, leg lowering, oxygen inhalation) were performed to improve the sensitivity of tests.
• TcpO2 results were recorded on a 1 Hz bais for of line analysis after anonymization.
• We recorded age , gender, weight, height, ongoing treatments , History of cardiac or respiratory disease.

Visual and mathematical analysis of the TcpO2 recording at the chest and limb level searching for various indices of TcpO2 variability at rest, or differences in responses between the chest and limb tcpO2 responses to provocative tests..

Enrollment: 300 estimated patients
