Abstract: Aerosolizable formulations are disclosed comprised of a pharmaceutically acceptable carrier, a pharmaceutically active drug or detectably labeled compound and a compound which is recognized by its distinct color, taste and/or smell even when present in a small amount and a low concentration. Examples of such compounds include menthol, peppermint, cinnamon and vanilla flavors and water soluble dyes. The compounds can be designed so that they are only detectable by a specific area of the tongue or seen under a certain wavelength of light. The degree of detection of the color, taste or smell of the compound is an indication of the degree of success in the delivery of an aerosolized formulation to a patient. The formulation is preferably delivered from a device which monitors and records information relating to the patient's respiratory movement and also scans and analyzes the aerosol prior to inhalation.

Abstract: An oxygen management device adapted to mount on a post on a compressed oxygen cylinder. The device includes a manifold block which is attached to the oxygen cylinder post. A pressure regulator is mounted directly on and is integral with the manifold block for reducing the oxygen pressure to a desired level. The manifold block also mounts an overpressure relief valve, a solenoid operated flow control valve, a bypass valve, a continuous flow restrictor and a pressure gauge. The manifold and the components mounted thereon, a control circuit and a battery for operating the control circuit are mounted in an annular housing which has a central opening for receiving the oxygen cylinder post. The control circuit senses when a patient inhales in a nasal cannula and opens the flow control valve to deliver a predetermined dose of oxygen to the nasal cannula at the beginning of inhalation.
