GAS ANALYZER
First Claim
1. An analyzer for detecting gas levels in a person'"'"'s expelled breath, said analyzer comprising:
- an inlet having a first open end formed to receive a person'"'"'s expelled breath;
first and second discrete chambers;
at least one channel communicating said first open end and said first and second discrete chambers; and
,means for simultaneously detecting the levels of at least two different types of gas in the expelled breath in said first and second chambers.

Abstract
The subject invention is directed to a breath analyzer which is capable of detecting toxic gas levels from breath analysis. The subject invention includes a mouthpiece which is in communication with a plurality of discrete chambers, such as first and second discrete chambers, each being provided with a separate probe for breath analysis. The probes are connected to analyzers for determining detected levels of gas. In a first embodiment, a first probe may be provided for carbon monoxide detection with a second probe being provided for hydrogen cyanide detection. Advantageously, with this arrangement, breath analysis may be conducted on-site, for example at the site of a fire, to quickly and simultaneously determine carbon monoxide and hydrogen cyanide levels in a person'"'"'s blood stream. In a second embodiment, a first probe may be provided for detection of carbon monoxide and a second probe may be provided for detection of hydrogen. With this arrangement, a calibrated correction of measured carbon monoxide data can be made to correct for improperly detected hydrogen. As such, a highly accurate on-site measurement for carbon monoxide can be achieved.
