Physiological Effects of Elevation
Reduced Atmospheric Pressure and Oxygen Availability
As you ascend to higher elevations, the atmospheric pressure decreases, resulting in a reduced availability of oxygen. This is because the air becomes thinner, containing fewer oxygen molecules per unit volume. At sea level, the partial pressure of oxygen (pO2) is about 100 mmHg, but it decreases with increasing altitude. For example, in Puno, Peru, located at an altitude of 3,827 meters (12,559 feet), the pO2 is approximately 60 mmHg.
This reduced oxygen availability has a significant impact on bodily functions. The body responds by increasing its breathing rate and heart rate in an attempt to compensate for the lower oxygen levels. However, this increased exertion can lead to fatigue and shortness of breath. In addition, the body produces more red blood cells to carry more oxygen in the bloodstream.
