Staying safe at altitude
The effects of the low oxygen levels experienced at altitude can be devastating and frequently fatal in the unprepared.
At sea level the normal oxygen concentration is 21%. At 12,000 ft the amount of oxygen is reduced by 40% and so breathing rate and cardiac activity need to increase to compensate for this deficiency. Unfortunately many of those affected by the condition still push onward despite warning signs and the body just cannot cope.
It can affect different people in a variety of ways ranging from mild headaches to sudden death. Both male and female can succumb rapidly and the condition can be seen at any age.
Frequently the deaths which occur are in the younger age group who tend to disregard the early warning signs.
