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 کاملHistopathology of radial keratotomy.
Report of a Case. A 39-year-old man with a history of RK performed elsewhere 8 years prior had complaints of decreased vision in both eyes. The patient’s preoperative refraction was –9.25 OD and –9.50 OS. According to the patient, the initial surgery was uncomplicated, although both eyes required enhancements. Cycloplegic refraction in our office was –3.50 +0.50 70 OD and –13.50 +1.00 100 OS, g...
متن کاملPurse-string sutures for hyperopia following radial keratotomy.
BACKGROUND Five years ago, we presented 19 procedures employing two intrastromal purse-string sutures to treat hyperopic shift following radial keratotomy. Thirty-four additional procedures and longer follow-up are now presented detailing the task of rehabilitating these eyes. METHODS Fifty-three eyes of 53 radial keratotomy patients who were unhappy with their uncorrected vision and who were...
