Oxygen Tension of Tissues by the Polarographic Method

Oxygen tension of tissues by the polarographic method. IV. Skin oxygen tension vs. arterial oxygen saturation; relationship to oxyhemoglobin dissociation curve.

Oxygen Tension of Tissues by the Polaro - graphic Method

Normal inclividuals breathing pure oxygen obtain full saturation of their hemoglobin, whereas those with right to left shunts do not. Oxygen hemoglobin dissociation curves indicate that increases to full oxygen saturation of hemoglobin are accompanied by marked increases of the oxygen tension. WVhen breathing oxygen fails to produce full saturation, relatively little change in oxygen tension oc...

Oxygen tension of tissues by the polarographic method. V. The rate of movement of oxygen from the peripheral artery to the skin.

Simultaneous measurements of skiml oxygen tension by polarography and skin temperature by thermocouple were made in patients with peripheral arterial disease and in individuals with normal extremities over a range of skin temperature of 10 to 50 C. The oxygen tension of the skin was found to increase as the skin temperature was raised to about normal body temperature in the ischemic extremity a...

Polarographic determination of oxygen tension of whole blood.

The purpose of this study is to establish a procedure for the direct determination of oxygen tension of whole blood that requires a smaller sample and simpler manipulation than methods previously reported (1). A procedure has been worked out for determining dissolved plasma oxygen which proved satisfactory in our investigations. Since the success of the application of the proposed polarographic...

Is oxygen consumption of surviving tissues determined by the oxygen tension of the suspension medium?

Oxygen tension in the suspension medium and oxygen uptake of the isolated diaphragm of the mouse have been determined simultaneously with systematic variation of shaking frequency and oxygen concentration of the gas phase. Oxygen tension in the suspension medium reaches its final value during the usual equilibration period of 10 minutes and remains constant for the whole measuring period. Each ...
