Book excerpt: Human tolerance to heat exposure is limited by body heat storage, as the body is unable to eliminate all the heat it produces and/or receives from the environment, and by the physiologic consequencies of such storage. Heat storage of about 80 kcal represents the 'voluntary heat tolerance' limit at which an average, fit, 170 kg man usually decides he is not willing to work much longer in the heat; and increase of 160 kcal in his heat content is associated with a 50% risk of heat exhaustion collapse. As the difference between skin and air temperatures decreases, a demand for evaporative cooling in the heat is imposed by the interplay of 3 factors: (a) the metabolic heat production; (b) the 'effective' solar heat load; and (c) the radiative and convective heat exchange through the clothing insulation. This demand may be greater than the maximum evaporative cooling allowed by 3 other factors: (a) the body's maximum sustainable sweat production (about 1L/hr approximately = to 675 Watts of cooling power); (b) the limit to sweat evaporation imposed by clothing moisture permeability and thickness; and (c) the difference between the vapor pressure of sweat at the skin surface and the ambient vapor pressure.

Download or read book Predictions of Human Tolerance to Heat Stress While Wearing Advanced Integrated Suit Concepts During Simulated Realistic Combat Scenarios written by and published by . This book was released on 1993 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aircrew garment ensembles with increased body surface coverage designed to enhance G-tolerance were modelled to determine their effects on thermal loading during simulated realistic combat Scenarios. Heat stress is known to decrease G-tolerance. Physiologic responses were estimated using the Texas Human Thermal Model (THTM). Predictions included rectal and mean skin temperatures, heart rate, sweat rate and accumulated sweat (SWT) during an 'alert 5' with aerial combat maneuvers and normal operations with/without ACM. Five ensembles were modelled: USN winter ensemble with (WE) or without an EAGLE with a USN COMBAT EDGE (CE) counter pressure jerkin and a USN summer ensemble with CE and either an EAGLE (E), ATAGS (A) or ATAGS with additional arm coverage (AA). Simulations were run under cool, warm and hot conditions. Since no fluid intake was allowed during these simulations, SWT provided an estimate of dehydration. The hot "alert 5" scenario was the most thermally stress due to the waiting period on the flight line without cooling. Reduced G-tolerance was predicted prior to simulated engagements with degraded CNS function for WE, A and AA. Similar CNS function deficits were not predicted for other scenarios. Few statistical differences were found during warm conditions for any scenario. Overall, E was predicted to produce a relatively lower thermal load than the other summer ensembles. External cooling should be provided during hot "alert 5" conditions to avoid negating the enhanced G-tolerance benefits obtained from wearing increased coverage anti-G suits.
