Abstract
Inhalation therapy apparatus comprises a mouthpiece through which air is to be inhaled and provides a pneumatic signal related to the volume of air inhaled. The pneumatic signal is transduced to electrical information and provides visual indicia to be observed by the patient to encourage the patient's performance. One row of lights indicates a desired level of inhalation to be attained, while a parallel row of lights indicates the inhalation actually attained. A step wise visual configuration also is provided encouraging the patient to increase his inhalation step by step. A visual display is also provided of the total number of attempts or inhalations, and also the number of times that the desired volume is attained.
