ABSTRACT:
An incentive lung exercise apparatus includes an inhalation spirometer, a coupling attached thereto with a unidirectional outlet valve and a source of oxygen. A relatively long flexible hose connects this portion of the structure to a mouthpiece or face mask and medication nebulizer which can be held by a patient. Oxygen and medication can be administered while the patient is using the spirometer structure for lung exercise following surgery or the like. Oxygen is passed through a small hose within the major hose, leaving a substantial volume to retain exhaled gas which is then rebreathed, giving the patient greater incentive to utilize the apparatus for maximum lung inflation. A further small hose can be included and connected to an infrared capnograph for monitoring CO.sub.2 in the hose. Control of the depth of respiration is accomplished by varying the oxygen flow and inspired carbon dioxide content as judged by the analyzed expired endtidal carbon dioxide content.
