Can Eolos improve breathing at high altitude?
Oxygen deprivation is usually a result from being at high altitude or just climbing up a flight of stairs. There are two major kinds of environmental stresses at high altitude: climate and low air pressure. The percentage of oxygen in the air at two miles (3.2 km.) is the same as at sea level (21%). However, at a higher altitude, the air pressure is 30% lower because the atmosphere is less dense. At high altitudes, the lower air pressure makes it more difficult for oxygen to enter our vascular systems. The result is hypoxia or oxygen deprivation. Hypoxia usually begins with the inability to do normal physical activities without fatigue. When this happens, there is an increase in breathing and heart rate to as much as double even while resting. Pulse rate and blood pressure go up sharply as our hearts pump harder to get more oxygen to the cells. Under these conditions, just to put one foot in front of the other requires maximal levels of breathing. Physical performance is harder because
