Abstract
The Bureau of Mines conducted tests designed to compare its breathing metabolic simulator (bms) with other methods that are currently used to evaluate the performance of respiratory protective equipment. The bms is a commercially developed device that uses a piston cylinder to stimulate breath movement. Using a propane furnace that consumes oxygen and forms co2, the bms also simulates the respiratory metabolism of humans. The breathing and metabolic subsystems of the bms are described in detail in this report. Results are compared from tests that used the bms to evaluate respiratory equipment and from tests that used human subjects for the same purpose. The bms was also tested against a pulsatile breathing machine (pbm) previously designed by the Bureau. Both machines were used to test respiratory equipment, and the test results are compared in this report. This research showed that bms test results compared more closely to the results of tests that used human subjects than did results obtained using the pbm.
