Digital computers are becoming important diagnostic and research tools in the pulmonary function laboratory. Their applications include generating reports, file-keeping analyses of data from spirometry and stress testing procedures, graphically present-ing data, and statistically reducing research data. The computer can be used to develop models of the respiratory system that can be practically applied to obtain more detailed information concerning the flow-limiting aspects of airway segments during forced exhalation. With the computer system's intended use in mind, the purchaser should consider a computer system's capacity, the expandability of the system, the manufacturer's reliability and service record, and the availability of necessary software.
