Related to tissue oxygenation: Oxygen saturation
The oxygen level in tissues. Measurement of the oxygen concentration in body fluids is not as important as knowing the oxygen level in the tissues themselves. Determining the gastrointestinal interstitial pH provides an indication of the adequacy of tissue oxygenation. Decreased oxygen supply leads to anaerobic metabolism in cells, which produces a fall in pH. Thus the tissue pH serves as a marker for the adequacy of oxygen supply in the tissues.
