title: Microcomputer-assisted on-line measurement of breathing pattern and occlusion pressure.
abstract: A flexible system has been developed for on-line breath-by-breath measurements of variables commonly included in studies of breathing pattern and mouth occlusion pressure (P0.1). The system, utilizing analog signals for mouth pressure and inspiratory flow as inputs, includes a breathing pattern monitor and a pneumatically driven occlusion device designed to be compatible with a low-cost microcomputer and analog and/or digital readout instruments. The design of the system permits accurate breathing pattern and P0.1 measurements even at the highest flow and breathing frequency encountered in muscular exercise studies.
