This paper describes the Bureau of Mines efforts to develop breathing and metabolic simulator technology. Breathing simulation has been widely achieved throughout the world and used in the testing of open circuit breathing apparatus, but satisfactory metabolism simulation has not been achieved. This situation required that the testing of closed-circuit breathing apparatus, with which the Bureau deals exclusively, be done using human test subjects. The goal was a machine that could accurately simulate both the breathing and the metabolic functions of a human being for testing of closed-circuit breathing apparatus. The advantages of using such a machine instead of a human being for testing respiratory protective devices lie in its ability to quantify metabolic input, its repeatability, and the lack of a need to deal with the vagaries of human subjects. This report describes the breathing and metabolic simulators that have been developed and used by the Bureau over the past 15 yr.
