Abstract:
1. A method for optimizing the accuracy of at least one of a carbon dioxide elimination measurement and a carbon dioxide excretion signal obtained from an individual based on carbon dioxide stores of a respiratory tract of the individual, comprising use of the formula: where {dot over (V)} M CO 2 (n) is the carbon dioxide elimination measurement, {dot over({circumflex over (V)})} B CO 2 (n−1) is an estimate of carbon dioxide excretion of at least one preceding or subsequent breath, {dot over({circumflex over (V)})} B CO 2 (n) is an estimate of carbon dioxide excretion of the same breath as that for which the carbon dioxide elimination measurement was obtained, and α is a transformation coefficient based on an estimate of the carbon dioxide stores of the respiratory tract of the individual.
