Real-Time Electrocardiogram Transmission from Mount Everest during Continued Ascent
The feasibility of a real-time electrocardiogram (ECG) transmission via satellite phone from Mount Everest to determine a climber's suitability for continued ascent was examined. Four Taiwanese climbers were enrolled in the 2009 Mount Everest summit program. Physiological measurements were taken at base camp (5300 m), camp 2 (6400 m), camp 3 (7100 m), and camp 4 (7950 m) 1 hour after arrival an...
متن کاملAppetite at "high altitude" [Operation Everest III (Comex-'97)]: a simulated ascent of Mount Everest.
We hypothesized that progressive loss of body mass during high-altitude sojourns is largely caused by decreased food intake, possibly due to hypobaric hypoxia. Therefore we assessed the effect of long-term hypobaric hypoxia per se on appetite in eight men who were exposed to a 31-day simulated stay at several altitudes up to the peak of Mt. Everest (8,848 m). Palatable food was provided ad libi...
متن کاملClimbing Mount Everest Without Oxygen
The ascent of Mount Everest (altitude 8,848 m) by two climbers without supplementary oxygen in 1978 was a feat that astonished many physiologists; indeed, measurements of maximal oxygen uptake at lower altitudes suggested that it would be impossible. Data obtained in 1981 at extreme altitudes, including the summit itself, showed that man can tolerate the extreme hypoxia only by an enormous incr...
متن کاملVisualization and Animation of Mount Everest
In the year 1988 a new topographical map 1:50’000 of the Mount Everest region was published by the National Geographical Society. The full map content was derived from aerial images of scale 1:35’000, acquired in a 1984 photogrammetric flight. This highly acclaimed topographical map, produced with Swiss photogrammetric and cartographic know-how, serves until nowadays as an important work of ref...
متن کاملPulmonary gas exchange on Mount Everest.
The paper by PEACOCK and JONES [1], "Gas Exchange at Extreme Altitude: Results from the British 40th Anniversary Expedition", presented in this issue of the Journal, reports fascinating new data recorded at extreme altitudes (up to 8,000 m) on Mount Everest. Among the interesting findings, was the fact that, on the South Col (altitude 8000 m), alveolar oxygen tension (PA,O2) (measured with a fu...
