Mapping Of Transcutaneous Oxygen Tension In Different Physiological Conditions
Amany Mohamed El Ameen Ali El Said;
Abstract
Transcutaneous measurements of 02 ( Tcpo2 )
. provide continuous and noninvasive estimation of arterial blood gases and indicator of local tissue perfusion by skin surface. In the practical situation of transcutaneous measurements, gases are transferred from the dermis through the epidermis and a layer of contact fluid to the sensor. Heating the sensor affect the permeability of the skin. It has a marked effect on cutaneous blood and gas diffusion through the stratum corneum.
Transcutaneous oxygen tension ( Tcpo2 )
measurement appears to be a useful tool for assessing oxygen tension in the blood of the skin capillaries.
Different methods are used to evaluate the
microcirculation of the skin, like capillary microscopy, laser doppler and Tcpo2.
The Tcpo2 measurement is reliable non invasive and
simple. But its values are dependent on a lot of different parameters, which must be taken in account when Tcpo2 measurements are interpreted. These factors include skin thickness, density of sebaceous gland, capillary density and capillary blood flow.
The aim of this work was therefore to map Tcpo2 of
the body in nine locations, at different degrees of temperatures 37 °c, 40 °c and 45 °c, and to determine the
