| Abstract: | The feasibility of measuring oxygen saturation in venous blood both by artificial modulation of the volume of tissue filled
with blood and by determining the respiratory rhythm from a Fourier spectrum is demonstrated. Both methods have advantages
and limitations. The results obtained by the two methods correlate well with one another and with published data. |
