• Changes of Hemoglobin Concentration in the Brain by changing position measured by NIRS

抄録

The aim of this study was to investigate the changes of Hb concentration (Hb. C) in the brain measured by NIRS (Near-infrared Spectroscopy) during position change of the body. Blood pressure (BP) and heart rate (HR) were measured to compare with the changes of Hb.C simultaneously. The subjects were twelve normal adults, four SCD patients and three stroke patients. Body position of the subjects was changed from supine (Sup) to standing (Std) and Std to Sup successively. The values measured in the first Sup were adopted as base line. In normal adults, Oxy Hb. C decreased in Std and increased in second Sup, while the change of Deoxy Hb. C was reverse to that of Oxy Hb. C. Both BP and HR increased in Std and decreased in second Sup. However Oxy Hb. C in SCD patients showed similar change to that in normal adults, there were no remarkable changes of Oxy Hb. C in stroke patients. It was suggested that the changes of Hb. C measured by NIRS were useful for detecting the vascular reaction in the brain.
