  • Patent number: 4296756
    Abstract: A remote pulmonary function tester uses a microcomputer to receive patient identification data, direct the test sequence, store several FEV maneuvers, and then transmit the stored data in a digital format to a central computer. The central computer plots a flow volume curve, computes FEV, FEF.sub.25-75% etc., compares these values with normals, and performs a preliminary disease categorization. The pulmonary function tester comprises a flow to pressure transducer, producing an analog signal, an analog to digital converter for digitizing the analog signal, a touch tone keyboard for simple patient identification data entry, and a microcomputer system having a read/write storage for storage of test and patient identification data, communication interface for connection to a central computer through telephone lines, and a read only memory and a central processing unit for control of the tester.
