Interior structural firefighting involves heavy physical exertion under extreme environmental conditions. Personal protective clothing and equipment impose 50 lbs of weight on fire fighters and impede the evaporative cooling mechanisms normally responsible for thermoregulation during exercise. The intense heat of the fire ground further exacerbates the physiological stress on working fire fighters. Occupational morbidity and mortality statistics reflect the impact of such stressors on fire service personnel. Non-invasive physiological monitoring capabilities are needed to more precisely define the cardiovascular responses to the demands of fire fighting and identify markers of impending failure of compensatory mechanisms prior to collapse or onset of irreversible pathology. A suite of sensors designed to provide continuous remote monitoring of fire fighters has been developed. Oximetry sensors are incorporated into SCBA facemask to allow unencumbered monitoring and analysis of cardiovascular and pulmonary function. The present report also describes a model system for physiological studies of fire fighting. This system comprises a series of timed simulations of fire ground tasks performed by fire fighters in a heated environmental chamber. Preliminary testing confirms the feasibility of reliable oximetry signal acquisition under fire ground conditions.
