Abstract: Exercise-induced arterial hypoxemia (EIAH) is a recognized phenomenon in healthy subjects, although its epidemiology and mechanisms remain incompletely understood. In this study, we assessed the prevalence rates of EIAH among various populations. Eighty-two subjects underwent incremental exercise protocols to maximum volitional fatigue while being monitored using forehead pulse oximetry. Pre- and post-exercise spirometric testing as well as serum lactate measurements were utilized. Results were stratified by severity of oxygen desaturation, gender, age, training, fitness level, and mode of exercise, and statistically compared to determine EIAH prevalence and characteristics of the desaturating populations. The prevalence of EIAH in our study population was 35.4% (37.1% for males and 30% for females), which was significantly lower than that reported previously. We additionally observed a higher prevalence of EIAH in moderately fit individuals than previously documen!
ted (32.7%) and a low prevalence in the least trained subjects (36.8% vs. 12.5%). Younger subjects displayed a trend towards greater development of EIAH, contrary to past observations. Spirometric analysis revealed no statistically significant differences in lung volumes and flow rates between individuals with normal saturation and those who displayed desaturation. Serum lactate measurements did not differ significantly between normal and desaturating populations. Our documented prevalence of EIAH is significantly lower, but more common in less fit and younger individuals, compared to previously published findings.
