Abstract
Exertion-Induced Desaturation (EID) is a common complication of numerous pulmonary disorders and often treated with supplementary oxygen during exertion. We performed a systematic review and meta-analysis of Randomized Clinical Trials (RCTs) to evaluate the efficacy of supplementary oxygen for EID in pulmonary disorders.Medline and Embase were systematically searched from July 2022 to June 2023 following PRISMA guidelines. RCTs that met predefined inclusion criteria were included. Means and Standard Deviations were extracted and Standardized Mean Differences (SMD), the difference in means between groups divided by the Standard Deviation, and 95% Confidence Intervals (CI) calculated. Exercise capacity was the primary outcome; exercise dyspnea, baseline dyspnea, quality of life were the secondary objectives. The immediate, post-rehabilitation, short-term, and ambulatory effects of oxygen supplementation were evaluated.We included 15 studies in our analysis. Oxygen supplementation to treat EID had been investigated for Chronic Obstructive Pulmonary Disease (COPD) and Interstitial Pulmonary Fibrosis (IPF) only. Oxygen supplementation was superior to placebo for its immediate effect on exercise capacity for COPD (SMD: 0.42, 95% CI: 0.15 to 0.69, I2=3%) and IPF (SMD: 0.41, 95% CI: 0.08 to 0.75, I2=57%) and exercise dyspnea for COPD (SMD: −0.40, 95% CI: −0.76 to −0.04, I2=31%). Sensitivity analysis revealed similar results.Our study revealed efficacy of supplemental oxygen for EID and only a positive immediate effect on exercise capacity and dyspnea but no improvement in short-term or long-term measures.
