Altitude Illness
Mountains cover one-fifth of the earth’s surface; 38 million people live permanently at altitudes ≥2400 m, and 100 million people travel to high-altitude locations each year. Skiers in Aspen, religious pilgrims to Lhasa, trekkers and climbers to Kilimanjaro or Everest, and military personnel deployed to high-altitude locales are all at risk of developing acute mountain sickness (AMS), high-alti...
متن کاملHypoxic ventilatory response in successful extreme altitude climbers.
A very high ventilatory response to hypoxia is believed necessary to reach extreme altitude without oxygen. Alternatively, the excessive ventilation could be counterproductive by exhausting the ventilatory reserve early on. To test these alternatives, 11 elite climbers (2004 Everest-K2 Italian Expedition) were evaluated as follows: 1) at sea level, and 2) at 5,200 m, after 15 days of acclimatis...
متن کاملThe physiologic cipher at altitude: telemedicine and real-time monitoring of climbers on Mount Everest.
Advanced wearable biosensors for vital-signs monitoring (physiologic cipher) are available to improve quality of healthcare in hospital, nursing home, and remote environments. The objective of this study was to determine reliability of vital-signs monitoring systems in extreme environments. Three climbers were monitored 24 hours while climbing through Khumbu Icefall. Data were transmitted to Ev...
متن کاملPhysiological profile of world-class high-altitude climbers.
The functional characteristics of six world-class high-altitude mountaineers were assessed 2-12 mo after the last high-altitude climb. Each climber on one or several occasions had reached altitudes of 8,500 m or above without supplementary O2. Static and dynamic lung volumes and right and left echocardiographic measurements were found to be within normal limits of sedentary controls (SC). Muscl...
متن کاملAltitude-related illness.
There are a number of conditions which can be grouped together as ARI. Many represent potentially fatal pathophysiological states that are rapidly reversible if identified and treated properly. Physiological alterations that result from the hypobaric hypoxia of altitude include cerebral vasodilatation, altered ventilatory patterns, pulmonary vasoconstriction, decreased cardiac output, and alter...
