The invention relates to a respiration analysis system and method. In particular, the present invention relates to a breath analysis system and method for determining the effectiveness of a measurement of the concentration of drunkenness substances in the exhaled breath of a user and thereby reducing the risk of tampering with the result without increasing analysis time or inconvenience to the user. A line-of-sight detector is provided and its output signal is compared to a tracer quality signal to determine if the signal has a corresponding expected behavior and relationship.

    本发明涉及一种呼吸分析系统和方法。特别地,本发明涉及一种呼吸分析系统和方法,用于确定用户的所呼出呼吸中致醉物质的浓度的测量的有效性,并且从而降低篡改结果的风险,而不会增加分析时间或对用户的不便性。提供视线检测器,并且将其输出信号与示踪物质信号进行比较,以确定所述信号是否具有相应的预期行为和关系。
