High pressure nervous syndrome (HPNS) is a neurological and physiological diving disorder that results when a diver descends below about 500 feet (150 m) while breathing a heliumoxygen mixture. This study investigated the role of biomarkers and their interactions with each other and with the clinical parameters to study the physiology of high-altitude pulmonary edema (HAPE) in HAPE-patients (HAPE-p) against adapted highlanders (HLs) and healthy sojourners, HAPE-controls The variation in barometric pressure which occurs with latitude influences enormously the inspired oxygen concentration at extreme altitudes and can significantly effect performance.

As riders, mountaineers, and out doors people, we know that some of the best of what the outdoors has to offer is often found above Symptomatic high-altitude pulmonary hypertension is a unique illness seen mostly in infants. The physiology of altitude sickness centres around the alveolar gas equation; the atmospheric pressure is low, but there is still 20.9% oxygen. adaptation, in biology, the process by which a species becomes fitted to its environment; it is the result of natural selections acting upon heritable variation over several generations. Mountain medicine recognizes three altitude regions that reflect the lowered amount of oxygen in the atmosphere: High altitude = 1,5003,500 metres (4,90011,500 ft) Very high altitude = 3,5005,500 metres (11,50018,000 ft) High Altitude. The relative concentration of oxygen in the atmosphere remains constant at 20.95 percent up to approximately 110,000 m (360,892 ft), but because air is compressible, the pressure it exerts is Altitude Sickness.
