ABSTRACT:
A device and method for measuring critical portions of an individual's forced expiratory efforts. The device includes a series of preset negative pressure sensors attached to a sensor port located in a breathing tube of predetermined dimension. A patient blows through the breathing tube triggering the various sensors depending on the airflow rate. The time each of the sensors are activated is recorded. The recorded information can be used to determine various diagnostic parameters.
