Method of analyzing components of alveolar breath
First Claim
Patent Images
1. A method of analyzing alveolar breath comprising:
- expiring breath through an analysis chamber;
continuously monitoring a concentration of a first component of the breath as the breath is expired through the analysis chamber to determine when alveolar breath is in the analysis chamber; and
triggering at least one concentration measurement of a second component of the breath once the alveolar breath is in the analysis chamber.

Abstract
A method of analyzing alveolar breath. Breath is expired through an analysis chamber. The concentration of a first component of the breath is monitored as the breath is expired through the analysis chamber. When the concentration of the first component indicates that alveolar breath is in the analysis chamber, at least one concentration measurement of a second component of the breath is triggered. Concentration measurements of the second component are discontinued when the concentration of the first component indicates that alveolar breath is no longer passing through the analysis chamber.

20. A method of analyzing alveolar breath comprising:
-
expiring breath through an analysis chamber;
passing light through the breath in the analysis chamber, the light comprising a first wavelength corresponding to a first absorption feature of a first component of the breath;
continuously measuring absorption of the light at the first wavelength by the first component to determine when alveolar breath is present in the analysis chamber; and
triggering at least one concentration measurement of the second component of the breath once the alveolar breath is in the analysis chamber. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31)

32. A method of analyzing alveolar breath comprising:
-
expiring breath through an analysis chamber;
passing light through the breath in the analysis chamber, the light comprising a first wavelength corresponding to a first absorption feature of a first component of the breath;
continuously calculating a concentration of the first component of the breath by monitoring absorption of the light at the first wavelength by the first component;
comparing each calculated concentration of the first component to determine when alveolar breath is present in the analysis chamber; and
triggering at least one concentration measurement of the second component of the breath once the alveolar breath is in the analysis chamber. - View Dependent Claims (33, 34, 35, 36, 37, 38, 39, 40, 41, 42)
