Embodiment Construction
[0095] Described herein are devices and methods for creating a registry of respiratory gas samples and analyzing the gases in that registry for desired monitoring, screening, or diagnostic purposes. In the illustrated embodiment, for exemplary purposes, a sample of the patient's breath is shown drawn from the patient into the instrument by application of a vacuum. However, the present invention also applies the patient's breath to the instrument in order to allow the instrument to collect breath samples without the need for vacuum application.
[0096] In some variations, one or more breath parameters are measured to identify different components of the breath and corresponding time periods, and a pneumatic system is used for capturing the portion of exhaled breath in the sample tube using the identified time periods. In some variations, one or more valves and / or flow control mechanisms (such as vacuum pumps, for example) are used to regulate the flow rate of gas drawn into th...
