Abstract: Hidalgo Equivital(TM) Physiological Monitor and other sensors performance monitoring of physiological status was evaluated, and human data were collected on 12 wildland firefighters (WLFF). The devices were provided to the University of Montana Center for Work Physiology and Exercise Metabolism (WPEM) to collect data relative to energy costs and thermal strain. The Hidalgo system collected, recorded and displayed heart rate (HR), respiratory rate (RR), body position, core temperature (CT), and skin temperature (ST). CT was obtained using the VitalSense monitor with ingestible temperature pills. Other sensors were an ActiCal activity monitor and a Garmin Forerunner 301 GPS. Relative to other devices used by WPEM, the sensors performed well. Setup and data download was trouble-free, making field use of Hidalgo units practical and feasible. Data management performed well, but it was sometimes difficult to convert to other data formats. Some telemetry pills died or read too low. CT changes little despite fluctuations in RR and HR. Those data, collected from the Hidalgo system, appear reasonable for WLFF activities.
