Official title
Validation of Exhaled Carbon Monoxide for DLCO Correction
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
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.
