Cardio Respiratory Adjustments to High Altitude
ثبت نشده
چکیده
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 (HAPE), high altitude cerebral edema (HACE) and cold injuries. This review describes cardio respiratory changes occurring on acute induction of subjects to high altitude and during their acclimatizing period. In addition, it also outlines the pathophysiology, treatment and prevention of the common high altitude (HA) maladies.

The physiology of high altitude: an introduction to the cardio-respiratory changes occuring on ascent to altitude
Both the high altitude physiologist and the intensivist are challenged by the human organism in a hypoxic environment. The variation in barometric pressure which occurs with latitude influences enormously the inspired oxygen concentration at extreme altitudes and can significantly effect performance. The cardiorespiratory changes which take place at high altitude, and in particular the putative...
متن کاملRespiration at High Altitudes *
It has been clearly recognized that a low barometric pressure, when first encountered, may interfere with the normal workings of the human machine, but that later by compensatory responses the body may become adapted to the new conditions. The outstanding variable encountered in ascents to high altitudes by airplane, dirigible, free balloon, or mountaineering is the tenuousness of the atmospher...
متن کاملRisk assessment for a high-altitude alpinist with coronary artery disease
Dear Editor, we report the case of a 60-year-old man, professional climber, who was attending a mountaineering expedition in Annapurna. At an altitude of about 5500 m the patient felt sudden onset of dyspnea, out of proportion to the effort he was making, for which he was trained. After coming back to Italy, the patient underwent cardiologic examination. A 12-lead electrocardiogram (ECG) was pe...
متن کاملMechanisms of hemoglobin adaptation to high altitude hypoxia.
Evidence from a number of vertebrate taxa suggests that modifications of hemoglobin (Hb) function may often play a key role in mediating an adaptive response to high altitude hypoxia. The respiratory functions of Hb are a product of the protein's intrinsic O(2)-binding affinity and its interactions with allosteric effectors such as protons, chloride ions, CO(2), and organic phosphates. Here we ...
متن کاملView From Above: Bibliometric and Citation Analysis of Global High Altitude Medicine Research
Introduction: High altitude destinations are popular among international travelers. Travel medicine practitioners should be familiar with altitude physiology and high altitude illness recognition, prophylaxis, and management. We performed the first bibliometric analysis of high altitude medicine research. Methods: All articles published in a specialist hi...
