Ra. Deblasi et al., CEREBRAL AND MUSCLE OXYGEN-SATURATION MEASUREMENT BY FREQUENCY-DOMAINNEAR-INFRA-RED SPECTROMETER, Medical & biological engineering & computing, 33(2), 1995, pp. 228-230
Tissue oxygen saturation quantification was obtained using a frequency
-domain multi-source method based on two wavelength light-emitting dio
des. Brain saturation was 60.3 +/- 1.1% (n = 12). Brachioradial muscle
saturation declined during forearm ischaemia and maximal voluntary co
ntraction from 73.7 +/- 1.8 and 74.7 +/- 1.8% at rest to 44.2 +/- 3.3
and 61.4 +/- 2.9%, respectively.
