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 CO2 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.

Lung exercise apparatus comprising the combination of spirometer means for providing a measured amount of flow resistance to air drawn therethrough in one direction and for substantially preventing air flow therethrough in the opposite direction, said spirometer means having an air inlet and an outlet; means defining an elongated, flexible first hose connected at one end to said outlet and having patient-engageable means at the other end for forming a passage through which a patient can inhale through said spirometer means; nebulizer means having a gas inlet, a source of medication, and a medication outlet; means for attaching said medication outlet adjacent said patient-engageable means; an elongated, flexible second hose within said first hose, said second hose having a diameter significantly smaller than said first hose, said second hose having a first end near said spirometer outlet and a second end near said patient-engageable means; means at said first end of said second hose for connecting said second hose through a wall of said first hose to a source of oxygen; means at said second end of said second hose for connecting said second hose to said gas inlet of said nebulizer; and unidirectional valve means in said first hose for allowing gas to flow out of said hose, said valve means being separated from said patient-engageable means by a distance greater than the separation between said valve means and said spirometer outlet to form a substantial volume within said first hose for containing gas exhaled by said patient for rebreathing.
