ABSTRACT:
The device is a disposable compact unit comprising a transparent column with an aperture at its base, an air float within the column and with the column mounted on a closed container. A conduit joins the top of the column to an opening into the container. The container is also equipped with a breathing tube and a variable aperture means for varying the size of another opening into the container. By inhaling through the breathing tube, a patient can judge his capacity for alveolar expansion by the height to which the air float rises. Adjustment to any patient's capacity can be easily made by changing the opening in the variable aperture means.
