Chronic 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...
متن کاملInhaled nitric oxide for high-altitude pulmonary edema.
BACKGROUND Pulmonary hypertension is a hallmark of high-altitude pulmonary edema and may contribute to its pathogenesis. When administered by inhalation, nitric oxide, an endothelium-derived relaxing factor, attenuates the pulmonary vasoconstriction produced by short-term hypoxia. METHODS We studied the effects of inhaled nitric oxide on pulmonary-artery pressure and arterial oxygenation in 1...
متن کاملIncreased lung vasoreactivity in children from Leadville, Colorado, after recovery from high-altitude pulmonary edema.
Cardiac catheterization was performed on seven children after recovery from high-altitude pulmonary edema. All were life-long residents at elevations above 10,000 feet. Three of the seven had developed pulmonary edema without antecedent travel to low altitude but had an upper respiratory infection. Response of pulmonary arterial pressure to 16% inspired oxygen in all seven was compared with tha...
متن کاملCardio Respiratory Adjustments to High Altitude
Thousands of Indian lowlanders live and work at altitudes up to 6,400m in the western Himalayas for durations up to two years, and are exposed to hypobaric hypoxia and intense cold. Here, certain unique physiological changes occur in these individuals and they could also be afflicted with the well-known maladies of high altitude, i.e. acute mountain sickness (AMS), high altitude pulmonary edema...
متن کاملAugmented sympathetic activation during short-term hypoxia and high-altitude exposure in subjects susceptible to high-altitude pulmonary edema.
BACKGROUND Pulmonary hypertension is a hallmark of high-altitude pulmonary edema and may contribute to its pathogenesis. Cardiovascular adjustments to hypoxia are mediated, at least in part, by the sympathetic nervous system, and sympathetic activation promotes pulmonary vasoconstriction and alveolar fluid flooding in experimental animals. METHODS AND RESULTS We measured sympathetic nerve act...
