Susceptibility to decompression siclmess (DCS) is influenced by a multitude of factors. The purpose of this study was to determine the effect of age on susceptibility to DCS. A review of the literature on the relationship between age and susceptibility to DCS found an appreciable effect of age on group and individual susceptibility. Most of the studies reviewed were done during World War H and were limited to the age ...
The purpose of this study was to evaluate the effects of wearing MCU- 2/P and M-17 groundcrew chemical defense masks during steady-state work. Five MCU-2/P mask configurations (MC) were tested: mask without filter (MCU-OF), mask + 1 filter (MCU-1F), mask + 2 filters (MCU-2F), mask + 1 filter + air blower A (MCU-ABA), and mask + 1 filter + air blower B (MCU-ABB). Ten subjects walked on a treadmill (3 ...
An objective of this study was to evaluate the breathing resistance characteristics of MCU-2/P and M-17 chemical defense masks during individual exposures to 8 consecutive incremental workloads. Other objectives included: evaluation of cardiorespiratory and subjective responses and testing of two commercially available blowers. Five MCU-2/P mask configurations were tested: mask without filter (MCU-OF), mask + 1 filter (MCU-1 F), mask + 2 filters (MCU- 2F), mask + 1 filter + ...
