  • Method and apparatus for determining an indicator which is dependent on respiratory data
    Patent number: 6387053
    Abstract: In a method for the determination of an indicator which depends on respiratory data and defines the transition from the aerobic to anaerobic metabolism of a person, with the person being subjected to a physical stress, the O2 and CO2 concentration is measured directly in the respiratory gas stream of the person or in a partial stream derived there from. The time course of the concentration values or discrete concentration values are measured within at least one respiration period and the indicator defining the aerobic-to-anaerobic transition is derived from the time course of the concentration values or from discrete concentration values using a mathematical model.
