While descending, a person should be given extra oxygen, a process called oxygen therapy. In the event someone is experiencing severe symptoms of HACE, the only treatments are:ĭescending by at least 1,000 meters (3,281 feet) or the continued descent until symptoms improve is the best way to treat HACE. Most cases of HACE improve after one to three days. Treatment for High Altitude Cerebral Edema (HACE) Sleepiness – constant feeling of being tired, fatigue or drowsiness.Insomnia – continued sleeplessness, difficulty falling asleep, difficulty staying asleep.Climbers who experience the following during downtime may be suffering from high altitude cerebral edema. However, there are cases where HACE sets in over time. Most HACE cases come about rapidly with just minutes or a couple of hours of warning.

Generally, HACE can begin to occur in elevations of just 4,000 meters (13,123 feet) or higher. HACE is caused by exposure to extreme altitude environments, especially mountains above 8,000 meters (26,247 feet) where oxygen levels are low. A person affected by HACE will begin to develop fluid around the brain, eventually causing swelling, confusion and possibly death. High-Altitude Cerebral Edema (HACE) is a rare form of altitude sickness.

Persons most likely to suffer from these kinds of illnesses are mountaineers and rescue personnel. It is a broad term primarily used to describe Hypoxia, High-Altitude Cerebral Edema (HACE), High-Altitude Pulmonary Edema (HAPE) and Acute Mountain Sickness (AMS). In general, high altitude sickness covers a variety of illnesses brought on by exposure to high elevations. Reading up on the topic before an expedition can help you remember what to do in the event you or a fellow climber are experiencing medical difficulties brought on by these elevation-related illnesses. While on a mountain, elevation and the lack of oxygen can make it difficult to comprehend when you’re suffering from the effects of high altitude sickness. Being aware of high altitude sicknesses and expedition illnesses can mean the difference between life and death on the mountain.Īs the expedition seasons kick off, climbers should refresh themselves on the common signs of high altitude sicknesses and expedition illnesses they may encounter on the mountain. Here’s a list of the most common high altitude sicknesses and expedition illnesses.
