Outline of Final Research Achievements

The cerebral hypoxemia ratio can be monitored noninvasively as brain local oxygen saturation (rSO 2). Since the rSO 2 value does not require a pulse wave, it has a major advantage that it can be measured even for patients without self-heartbeat.
We measured to 33 people. At the start of the measurement in the ambulance, the rSO 2 value was almost the lowest value, but the increase in the rSO 2 value could be measured by cardiopulmonary resuscitation. However, although there was no significant difference, it was suggested that the rSO 2 value tended to be higher in the cases with return of spontaneous circulation (ROSC), and it was suggested that achievement of ROSC greatly contributes to improvement of the cerebral circulation. Measurement of rSO2 value in out-patient cardiopulmonary arrest patients was shown to be useful for prognostic prediction, assessment of resuscitation quality, and investigation of resuscitation in special situations.
