Paper Abstract

It is not known to what extent effects in extracerebral tissue influence non-invasive near infra-red optical measurement of cerebral arterial oxygenation saturation. Measurements were made at different positions on the forehead of six healthy adult male volunteers with arterial saturation near to 100%. The optical ratios between the pulse heights at different wavelengths were as expected from the spectral characteristics of hemoglobin, but showed an unacceptably large spread: the mean ratio between the 770 and 905 nm pulse heights was 0.69 (SD 0.08, range 0.50 - 0.95). We consider that this was due to pulsation of large extracranial arteries.
