Respirator Tolerance.

Abstract Respirator and personal factors affecting tolerance to respirator use were identified. The project evaluated interrelationships among various respirator loads, exercise level, personal characteristics, ventilatory, sensation, respiratory control, and subjective effects. Normal volunteers, industrial workers, and persons with mild respiratory impairment were used in laboratory and field tests on respirators. Flow resistance, dead space and pressure biasing were measured in response to respirator load. Respiratory pattern adaptation was investigated. Personal factors affecting tolerance were studied, including psychophysical load scaling sensitivity, and self rated tolerance. The author concludes that the safe and effective use of respirators necessitates attention to many factors, including personal characteristics and subjective effects. Human panel testing appears to have a major role in the objective evaluation of respirators.
