<abstract displayLabel="Summary">An automated version of a new method for quantitative respirator fit testing by controlled negative pressure was compared with a computerized aerosol fit system. The controlled negative pressure technique eliminates many of the problems associated with aerosol and pressure decay fit test methods. A series of fixed leaks was used to compare the leak measurement capablities of the controlled negative pressure system against a standard computarized aerosol fit test system</abstract>
