About 100 million individuals reside at high altitude (>2500m) worldwide, with the largest populations of highlanders being found in South America (Andean), central Asia (Tibetan and Sherpa) and East Africa (Ethiopian). Despite unique adaptations to hypoxia in these populations, chronic mountain
In a three week-period, healthy probands undergo 3 times a week a bicycle ergometer training in simulated altitude followed by 1 week passive exposure at simulated low altitude. 5 days after last exposure, a field study starts performing a rapid ascent to the Capanna Regina Margherita (4559m). Acute
Acute mountain sickness (AMS), high altitude pulmonary edema (HAPE), and high altitude cerebral edema (HACE) are complications of rapid ascent to high altitude. By definition, AMS is a benign condition, but it is likely that the same pathology underlies high altitude cerebral oedema (HACE). In
Compound danshen dripping pills is mainly used for the treatment and prevention of coronary heart disease and high-risk groups ,consists of Danshen (Radix Salviae Miltiorrhizae), Sanqi (Radix Notoginseng) and borneol.Danshen is the main drug efficacy of stasis, nourishing the nerves.Pharmacological
Acute Mountain Sickness (AMS) is a well described disease process that occurs as a result of rapid exposure to high altitude. High altitude headache (HAH) is defined as the presence of headache in the setting of a recent increase in altitude. When HAH is associated with nausea, vomiting, fatigue,
In a controlled and simulated avalanche scenario the investigators want to investigate how oxygen (O2) and carbon dioxide (CO2) diffuse and how rebreathing of CO2 in addition to mild hypoxia influence standardized physiological parameters in two scenarios: Fresh air and no fresh air delivered into
Preparation phase:
Eighteen asthma patients were selected based on physical and medical characteristics. During the year of preparation, several time points of evaluation were planned: evaluation at baseline, maximal exercise test in hypoxia (FiO2: 11%), 24hour stay at cold air environment.

Background
Altitude related illness, which include acute mountain sickness (AMS), high altitude pulmonary edema (HAPE) and high altitude cerebral edema (HACE), is common in subjects exposed to high altitude during professional or leisure time activities. There are independent risk factors such as:
Stroke is the second leading cause of death and a leading cause of long-term disability worldwide. Despite the spontaneous recovery that occurs following a hemispheric stroke, more than half of stroke patients show substantial residual impairments, imposing a significant human and economic burden.
