Studies in which the rate of local cerebral blood flow is determined by xenon-enhanced computerized tomography require measurement of end-tidal gas. A mass spectrometer and a thermoconductivity detector were compared in measuring the concentration of xenon in end-tidal gas both in humans and in a clinically simulated ("breathing bag") system. The experiments showed that the two instruments provided virtually identical results up to a rate of 18 breaths/min, at which rate recorded concentrations… CONTINUE READING
