Method of correcting componential concentration in expiration and expiration analyzer |
摘要 |
A first sample measuring passage provided between a collection port and a suction pump has a sample gas measurer for measuring expiration components, while a second sample measuring passage which is provided in parallel with the first sample measuring passage has a standard gas measurer for measuring O2 gas. Assuming that [A] represents a measured value of a target component in an expiration sample and [b1] represents O2 concentration in the expiration sample, correction is made on the basis of: [M]=f1x(21-[a1]) [A]/(21-[b1]) where [M] represents the corrected measured value of the target component, [a1] represents O2 concentration in end-tidal air which is supplied as a constant such as 15.3, for example, and f1 represents an experimentally prescribed coefficient such as 1.67, for example.
