Pathogenesis of higher ground. Is unknown But the study suggests that the body was not enough oxygen due to the higher oxygen content in the air is diluted. And the air pressure is dropping. As a result, the pressure of oxygen in the blood as well. The cold weather As a result, the body needs more oxygen. To provide energy to maintain body temperature. Furthermore, the body in the normal tourists are often dehydrated. The power / sweat on him. And water evaporation from breathing on him. Everyone will breathe faster All sent The severe lack of oxygen (Hypoxia or blood has less oxygen)
blood has less oxygen. And dehydration can affect blood circulation / blood. Blood pressure goes down The body needs to adapt in order to maintain blood pressure. And so the organ is the brain and lungs get sufficient oxygen. The body secretes chemicals in bulk. Catecholamines This will stimulate the heart. Increased heart rate, increased blood pressure. And improves the function of blood vessel walls, black
blood has less oxygen. Also stimulates blood circulation to the lungs and brain. To increase blood To increase oxygen
conditions these cause symptoms initially called Acute Mountain sick ness (AMS), which is adaptable and on their own pace. Symptoms usually recover back to normal within 2-3 days
, but if the body is unable to adapt. Or a lack of oxygen increases. Will result in a blood clot in various tissues, such as hand and foot, but a major cause is a severe blood clot in the lung and in the brain when a blood clot. Water will seep out of the blood vessel from the blood vessels into the tissue surrounding blood vessels. Thus causing a swelling of the hands and feet, but the key is the water retention in the lung tissue / pulmonary edema (Pulmonary edema) caused the so-called H PE (HAPE or High altitude pulmonary edema) and brain edema from there. Water retention in the brain tissue (Brain edema) caused the so-called H CE (HACE or High altitude cerebral edema), which both suffered a severe symptoms. May lead to death.
