Exhaled Carbon Monoxide (eCO) for Diffusing Capacity (DLCO) Correction

Summary

The purpose of this study is to check the accuracy of a procedure called exhaled carbon monoxide (eCO) testing. Exhaled carbon monoxide is used by physicians to help assess breathing in people with conditions like asthma and emphysema. eCO may be used to correct another breathing test (called diffusing capacity, or DLCO). Blood collection is usually required to correct the DLCO, so validation of the eCO test may help avoid that blood collection.
