  • Title: Mass spectrometry: application in the exercise sciences.
    Author: Wilmore JH.
    Journal: Crit Care Med; 1976; 4(5):230-4. PubMed ID: 975847.
    Abstract:
    This paper outlines a computerized system for monitoring physiological functions during exercise, using a mass spectrometer for analyzing the concentration of the mixed expired air. Examples are provided illustrating the operation of this system in both research and clinical situations. The most remarkable aspect of the system is its versatility, coupled with its accuracy. While the applications reviewed in this paper are rather narrow, work has been initiated using the mass spectrometer to measure residual lung volumes by the oxygen dilution technique, cardiac output by the CO2 rebreathing technique, and total body density by the helium dilution technique. The application of the mass spectrometer into other areas most certainty will occur in the near future.
