Official title
Effects of Altitude on Single-Breath Diffusing Capacity for Carbon Monoxide in Normal Subjects and Chronic Obstructive Pulmonary Disease
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The purpose of this study is to further understand the effects of altitude on the physiology of gas exchange in the pulmonary microcirculation in normal subjects and in people with chronic obstructive pulmonary disease (COPD) measured as the single-breath diffusing capacity for carbon monoxide (DLCOsb). The study will determine a mathematical formula to allow for altitude corrections in both study populations to be used clinically in pulmonary labs.
