To fulfill such a dream, it is our concern matter about what might be the potential factor affecting our journey at high altitude. We know the terms as an increase in height, level of oxygen in the air will decrease. Partial oxygen pressure of air in the surrounding environment is regarded as altitude sickness or mountain sickness.
Altitude sickness can occur to any people, especially the people who live at sea level need to take it seriously. It begins to appear from 3,500m above sea level. The symptoms may vary from person to person. The same symptoms may not appear to all people. The common symptoms of altitude sickness are

HACE and HAPE develop after the symptoms of altitude sickness or mountain sickness appear. Altitude sickness mainly causes whether to build up fluids in the lungs or to build up fluids in the brain. Entering water into the lungs is called "high altitude pulmonary edema" (HAPE) in medical terms. Water that collects in the brain is a condition called "high altitude cerebral edema" (HACE). Altitude sickness is more likely to incur people with a previous history of altitude sickness.
