Transcutaneous oximetry is measurement of tissue healability & is an assessment procedure that involves measuring the oxygen levels through a patient's skin. This information assists in decision making regarding vascular rehabilitation. A series of oxygen measurements can be used to monitor progress before & after various interventions regarding the healing potential of the tissue.
The earth's atmosphere normally exerts 14.7 pounds per square inch of pressure at sea level, which is equivalent to 1 atmosphere absolute. Normally we breathe approximately 20% oxygen & 80% nitrogen.
During HBOT. the pressure is increased up to two times the normal and the patient breathes 100% oxygen while the entire body is totally immersed in 100% oxygen. Since the oxygen is under increased atmospheric pressure, there is increased diffusion of the oxygen into the plasma, resulting in ultimately sustained delivery of increased oxygen to the oxygen-deprived tissues. This lead to accelerated healing of various types of persistent & problematic wounds.
“Hyper” means increased and “Baric” relates to pressure. Hyperbaric Oxygen therapy (HBOT) thus refers to intermittent treatment of the entire body with 100% oxygen at greater then normal atmospheric pressures.
