The primary objective of this program was to assess the feasibility of a master control unit for a respiratory protection system for the U.S. Army Chemical Research, Development, and Engineering Center. The intended function of the master control unit (MCU) includes monitoring physiological, environmental, and system performance conditions and controlling the components of a respiratory protection system to maximize both electrical efficiency and individual protection, yet minimize breathing effort. Instrumentation and sensors for measurement of physiological conditions were evaluated for use in the MCU. Commercially available positive pressure respiratory protection systems were surveyed and reviewed to determine their relevance for use in the MCU. In order to minimize the effort required to exhale while using a positive pressure respirator it was determined that an automatic valving system would be needed.
