    摘要： Use of co values in smoking cessation are described where an apparatus may be configured to encourage smoking cessation in a user. The apparatus may include a sampling unit which receives a sample breath and determines a level of exhaled carbon monoxide from the sample breath. The sampling unit may be programmed to initiate a first timer for tracking a cumulative time upon a determination that the level of exhaled carbon monoxide is below a predetermined threshold. The sampling unit may also be programmed to initiate a second timer for tracking a countdown time upon a determination that the level of exhaled carbon monoxide is above the predetermined threshold, wherein the countdown time corresponds to a second length of time until the carbon monoxide level within the body of the user is expected to dissipate below the predetermined threshold.

    摘要： Breath sensor measurement methods and apparatus are described. One variation may generally comprise a sampling unit having a breath sampling port, at least one pressure sensor located within the sampling unit and in communication with the breath sampling port, and a processor in communication with the at least one pressure sensor. The processor may be configured to prompt a user with instructions to exhale a sample breath for a first predetermined period of time into the breath sampling port and to inhale for a second predetermined period of time through the breath sampling port. The processor may be configured to measure a pressure change via the pressure sensor over the first and second predetermined periods of time such that the processor determines a total volume of air corresponding to lung capacity of the user based on the pressure change over the first and second predetermined periods of time.
