• Description:
  Tests were carried out in 11 individuals aged 20 to 42 years to determine the effect of respirator use on the pattern of breathing and to investigate the eventual effect of individual psychophysiologic sensitivity to resistances on the nature of breathing pattern adaptation. The subjects rated numerically a series of resistors to measure load scaling sensitivity (LSS). Stevens' Psychological Law was used to evaluate sensitivity in terms of slope relating log (sensation) to log (stimulus), with peak pressure and actual added resistance being the stimuli. Independently measured LSS during physical exercise, and during physical exercise with a respirator type of dead space or inspiratory resistance load, were inversely related to inspiratory time, peak pressure, duty cycle and tidal volume. The authors conclude that individual breathing pattern is affected by a psychophysiological characteristic which may affect normal adaptation to respirator use and suggest that workers sensitive to loads may have difficulties adapting to the use of respirators. Respiratory pattern, in addition to muscular ability to generate air flow, is stated as being a possible important parameter to consider in medically evaluating workers for respirator use.
