• Description:
  A number of volunteers participated in a study investigating the physiologic and subjective effects of single use (disposable) respirators during moderate exercise on a calibrated field course. Measurements were made non-invasively using respiratory inductive plathesmography, and subjective responses were evaluated with visual analysis scales. The presence of an expiratory valve on the respirator did not appear to have any measurable significant effect on physiologic response or on subjective response. For comparison, self-contained breathing apparatus affects were studied and were significant both physiologically and subjectively. This study suggests routine inquiry about subjective effects of single use disposable respirators is advisable, but that reliance upon physiological testing alone may be misleading.
