Pulmonary circulation and gas exchange at exercise in Sherpas at high altitude.
Tibetans have been reported to present with a unique phenotypic adaptation to high altitude characterized by higher resting ventilation and arterial oxygen saturation, no excessive polycythemia, and lower pulmonary arterial pressures (Ppa) compared with other high-altitude populations. How this affects exercise capacity is not exactly known. We measured aerobic exercise capacity during an incre...
متن کاملAbnormal circulatory responses to high altitude in subjects with a previous history of high-altitude pulmonary edema.
In five men with a history of susceptibility to high-altitude pulmonary edema (HAPE), hemodynamics and pulmonary gas exchange were measured at sea level, and again 24 hours following ascent to an altitude of 3,100 m. At sea level, all findings were essentially normal including a mean pulmonary arterial pressure (Ppa) of 13.8 + 1.9 mm Hg. None of the subjects developed clinically detectable pulm...

متن کاملChronic Mountain Sickness (Cms) Misdiagnosed As High Altitude Cerebral Edema (Hace) At Extreme Altitude (6400 M/21000 Ft)
Introduction: Chronic mountain sickness (CMS) represents a syndrome of secondary polycythemia along with thrombocytopenia, altered hemorheology, pulmonary and systemic hypertension, and congestive heart failure, occurring due to hypobaric hypoxia-anoxia-induced erythropoiesis reported in both native mountain residents and new climbers after prolonged stays at high and extreme a...

Reeves, John T., and Robert F. Grover. Insights by Peruvian scientists into the pathogenesis of human chronic hypoxic pulmonary hypertension. J Appl Physiol 98: 384–389, 2005; doi:10.1152/japplphysiol.00677.2004.—Pulmonary hypertension had long been suspected in high-altitude natives of the Andes. However, it remained for a team of Peruvian scientists led by Dante Penaloza to provide not only t...
