ABSTRACT:
A visual and auditory biofeedback system instructs patients in proper techniques of inhalation to administer aerosol drugs with Metered Dose Inhaler (MDI) devices. The system displays desired respiratory parameters along with real time performance with computer related technology means. Optimal performance parameters suited to individual patient needs may be generated. Suitable respiratory flow transducer means is used to generate air volume signals in real time, and suitable electronic switching means is used to indicate MDI activation in real time. Optional auditory incentive means are provided. Optional plus and minus error limits of acceptable performance are provided.
The system thus provides visual and auditory biofeedback incentives to improve patient or student performance to mechanical prescription parameters defined by the physician or instructor. Performance deficiency and performance enhancement indicators may be optionally used, both to enhance and to quality control performance. Performance records may be saved by suitable electronic means or hard copy for clinical or research needs.
In the preferred embodiments of the invention, the system may be implemented in either a suitable general purpose digital computer or similar specialized stand-alone computer related devices.
