What is transcutaneous oxygen tension?

Transcutaneous oxygen pressure measurement is a noninvasive test that assesses the partial pressure of oxygen diffusing through the skin. This study can be applied to any area of intact skin and records the oxygen-delivering capacity of the vascular system.

What is oxygen tension defined as?

Oxygen tension, or the partial pressure of oxygen (PO2), is the activity of the molecules of oxygen dissolved in the plasma. It is measured with a Clark electrode at a temperature of 37°C.

How do you measure oxygen tension?

Tissue oxygen tension may be measured by polarographic or dynamic fluorescence quenching methods, or using electron paramagnetic resonance (EPR) oximetry. The Clark polarographic technique (Fig. 2) consists of electrodes that generally contain a platinum cathode and a silver anode linked by a salt bridge.

What is the definition of transcutaneous oxygen measurement?

Transcutaneous oxygen measurement. Jump to navigation Jump to search. Transcutaneous oxygen measurement (TCOM or TcPO 2) is a non-invasive method of measuring the oxygen level of the tissue below the skin. Since oxygen is carried by the blood, TCOM can be used as an indirect measure of blood flow to the tissue.

What is transcutaneous partial pressure of oxygen ( TcPO2 )?

Transcutaneous Partial Pressure of Oxygen (tcPO2) as a Primary Endpoint to Assess the Efficacy of Celliant® as a Vasoactive Material 2 INTRODUCTION Celliant® technology is a patented process for adding micron sized optically active quartz, silicon oxide and titanium oxide particles to polymer fibers.

What should the oxygen tension be for a wound to heal?

In addition for the measurement to be normal, all parts of the oxygenation pathway must be functioning: the lungs must be able to oxygenate the blood, the heart must be able to pump the blood, and a patent artery must be able to carry blood to the skin. Without comorbitities, wounds are thought to be able to heal if the oxygen tension is >40 mmHg.

When do you need revascularization for transcutaneous oxygen?

In the presence of comorbities, such as diabetes or edema, a higher value is likely needed. Patients with oxygen tensions <20 mmHg are likely to need revascularization to promote adequate wound healing. The required TCOM level for adequate wound healing, however, remains controversial.
