An apparatus used in the medical industry such as an Incentive Spirometer, in order to increase transpulmonary pressure and respiratory volumes, to improve inspiratory muscle performance and re-establish the normal pulmonary hyperinflation, through the employment of electronic technology, providing audible, simulated, verbal, human sounding words, that assist, guide and prompt, increasing patient usage. In one embodiment, the Incentive Spirometer uses a capacitive sensing circuit preferably mounted to the side of the apparatus's housing for sensing movement of the float within the tube wall and for obtaining a measurement or reading of the patient's performance with the Incentive Spirometer. |
