Respiration 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 کاملCardiorespiratory changes with compact backpack system and distributed mode of load carriage.
In Indian Army, soldiers normally carry 21.4 kg in backpack (BP), haversack, and web distributed in different parts of the body and rifle in hand. This load distribution is unequal, may involve excess energy expenditure, mostly uncomfortable, and restricts the normal movement of the hand carrying rifle. A new BP has been developed which accommodates the rifle on sides leaving the hands free. Ph...
متن کاملKala-Azar at High Altitudes
Sir,?Major P. Savage, i.m.s., in the June number of your journal lias recorded the apparent occurrence of indigenous kala-azar at Sanawar in the Simla Hills, where up to that time the presence of Phlcbotomus argcntipcs, the suspected carrier of kala-azar, had not been reported. It is, therefore, of interest to note that in a collection of Phlcbotomus from Sanawar village, kindly given me by Cap...
متن کاملMetal layers at high altitudes
Introduction Conclusions References Tables Figures Back Close Abstract Introduction Conclusions References Tables Figures Back Close Abstract In the past, many studies have been carried out to demonstrate the influence of me-teoroids on the atmospheric metal layer, observed roughly in the altitude range 80– 105 km. Even with the capability of present day resonance lidars to measure metal densit...
متن کاملRespiratory and circulatory control at high altitudes.
Hyperventilation is one of the most important features of acclimatization to high altitude. Resting ventilation at extreme altitudes increases up to fourfold and exercise ventilation for a given work level increases to the same extent. Hypoxic stimulation of the peripheral chemoreceptors is the chief mechanism for the hyperventilation but there is also evidence that central sensitization of the...
