Interconnection of a spirometer and a sensor unit, with machine readable indicium

摘要: An improved spirometry assembly (20) is provided which includes a spirometer (22) and sensor unit (24) coupled via handle (26). The has reading slot (30) as well an optical reader (36). tab (72) having at least one characterizing indicium (76) thereon characterizes response parameter of the upon flow gas therethrough. In use, receives (36) reads generates data representative thereof sent to signal processor within (22). measuring device such pressure transducer in operative communication with interior for condition therein during patient-induced data. both report information about pulmonary patient.
