The present study was designed to examine how different tissue oxygenation parameters derived from NIRS reflect the changes in the forearm blood flow according to the brief ischemia and the subsequent reperfusion, and whether values of these parameters move in parallel with the medial and lateral sides of forearm blood flow.

In volunteers, brief ischemia was achieved using a blood pressure cuff applied to the examined upper arm at 180 mmHg. Continuous measurements of medial (or lateral) TOI in combination were performed (Trial 1) from the immediately before brief ischemia to 10 minutes after the release of a blood pressure cuff. Thirty minutes after the trial 1, the medial and lateral sides exchanged, and the continuous measurements were repeated (Trial 2).
In volunteers, brief ischemia was achieved using a blood pressure cuff applied to the examined upper arm at 180 mmHg. Continuous measurements of lateral (or medial) rSO2 were performed at the same time (Trial 1) from the immediately before brief ischemia to 10 minutes after the release of a blood pressure cuff. Thirty minutes after the trial 1, the medial and lateral sides exchanged, and the continuous measurements were repeated (Trial 2).
In volunteers, brief ischemia was achieved using a blood pressure cuff applied to the examined upper arm at 180 mmHg. Continuous measurements of forearm blood flow were performed for medial and lateral side from the immediately before brief ischemia to 10 minutes after the release of a blood pressure cuff.

Published
The tissue oxygenation index (TOI), regional saturation of oxygen (rSO2), skin tissue oxygenation (StO2), and FBF values were evaluated in the forearm. Medial rSO2 values at 1 to 3 minutes after the termination of brief ischemia were higher than lateral rSO2 and respective TOI values. FBF and StO2 values quickly increased according to the cessation of brief ischemia, whereas the medial and lateral values did not differ during and after the brief ischemia. TOI and StO2, but not rSO2, reflected changes in FBF of both medial and lateral sides simultaneously in response to the reperfusion after brief ischemia. The muscle tissue oxygenation during reperfusion favors the use of TOI and StO2, but not rSO2, as the surrogate parameter.
