Counterpoint: Pulmonary edema does not occur in human athletes performing heavy sea-level exercise

Abstract

The arterial partial pressure of oxygen (Pao2) can be reduced by as much as 30 mmHg and oxyhemoglobin saturation (Sao2) by 15% below resting levels in some aerobically trained athletes exercising at high intensities ([3][1]). Some have hypothesized that mild interstitial edema could develop and,
