Abstract
Methods and systems are described to obtain and analyze a gas sample from a desired section of the breath of a person, while accounting for erratic, episodic or otherwise challenging breathing patterns that may otherwise make the capturing of a gas sample from the desired section of breath difficult. These techniques may provide more reliable, accurate and adequate samples of gas such as end-tidal gas, and ultimately an accurate analysis of the sample captured.
Claims18
An apparatus for analyzing an exhaled breath, comprising:
- a sensor that measures a parameter of the exhaled breath;
- a first processor that determines if the measured parameter meets a predetermined criteria corresponding to a physiologically representative breath;
- and
- a breath sampling system that stores the exhaled breath when the first processor determines the measured parameter meets the predetermined criteria.
An apparatus for analyzing breath gas, comprising:
- a sensor that measures parameters of a first exhaled breath, a second exhaled breath, and a third exhaled breath;
- a first processor that determines if a first measurement of the first exhaled breath meets a first predetermined criteria;
- a second processor that determines if a second measurement of the second exhaled breath meets a second predetermined criteria, wherein the second measurement is made when the first measurement is determined to meet the first predetermined criteria;
- a third processor that determines if a third measurement of the third exhaled breath meets a third predetermined criteria, wherein the third measurement is made when the second measurement is determined to meet the second predetermined criteria;
- and
- a breath sampling system that stores the third exhaled breath when the third processor determines the third measured parameter meets the third predetermined criteria.
