Abstract:
Exercise-induced arterial hypoxemia (EIAH) occurs in some healthy humans at sea-level, whereby the most aerobically trained individuals develop the most severe hypoxemia. A female competitive runner completed 2 maximal exercise tests. Maximal oxygen consumption increased by 15% between testing days, but the degree of hypoxemia remained similar (PaO2, SaO2; 82 and 80 mm Hg; 93.8% and 92.8%; first and second test, respectively). Our case indicates that EIAH does not necessarily worsen with aerobic training.

Types of Hypoxia
There are four primary types of hypoxia, each resulting from a different cause:
1. Anemic hypoxia: This type occurs due to insufficient oxygen delivery caused by a lack of red blood cells (RBCs) or RBCs with abnormal or...
Acute Respiratory Failure-II
The underlying physiological abnormalities that contribute to hypoxemic respiratory failure include:
Treatment for Pulmonary Arterial Hypertension: Oxygen Therapy for Respiratory Failure
Oxygen therapy is vital in increasing and maintaining blood oxygen levels in PAH patients. As a result, it aids in reducing fatigue,...
Hyperpnea and Hyperventilation
Exercise and Cardiovascular Response
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...
