| 20110009765 | Methods of Detecting Gaseous Component Levels in a Breath - Method for detecting gaseous component levels in a breath, comprising: receiving a breath through a breath channel, wherein the breath channel is in fluid communication with a flow rate sensor and an electrochemical fuel cell gas sensor; measuring a flow rate of the breath received through the breath channel; measuring a first time, wherein the first time corresponds to an amount of time elapsed while receiving the breath in the breath channel; and calculating a current gaseous component level utilizing the flow rate, first time and an output from the gas sensor. Methods for detecting an error condition while measuring gaseous component levels in a breath comprising: determining if the peak output occurs while breath is still being received in the breath channel; and if the peak output occurs while breath is still being received in the breath channel, alerting a user of an error condition. | 01-13-2011 |
