The effect of hypoxic relapse of chronic obstructive pulmonary disease (COPD) on lung adenosine triphosphate (ATP) concentration was studied measuring ATP in exhaled breath condensate (EBC). ⋯ ATP detected in EBC indicates the presence of ATP in airway lining fluid. Lack of difference in ATP concentration between health and COPD suggests that airway ATP level is under complex control of multiple factors.
