Abstract: A system for delivering an agent to be taken up by a user's lungs and for simultaneously monitoring the user's lung health includes an inhalant-flow detection system and a computer-executable medium. The inhalant-flow detection system includes a flow sensor arranged to intercept a portion of inhalant flowing through the system and to provide detection signals regarding inhalant speed as a function of time. The computer-executable medium includes non-transient computer code, which when executed on a computer, causes the computer to receive the detection signals from the flow sensor, receive information about a quantity and type of agent provided by the agent delivery device for the inhalant during the inhalation time period, and calculate a delivered dose of the agent based on at least the detection signals received, the information received about the quantity and type of agent, and information concerning physiology of the user.

Abstract: An apparatus including a blower configured to provide a supply of breathing gas, and a delivery tube configured to deliver the supply of breathing gas to a user breathing interface. The delivery tube has an inside diameter of about 15 mm or less. The apparatus also including a control system configured to provide a control signal to the blower for controlling a pressure of the supply of breathing gas to between about 1 cm H2O to about 6 cm H2O at the user breathing interface. The control signal is based upon, at least in part, one of a pressure and a flow rate of the supply of breathing gas at the user breathing interface.

Abstract: The present invention relates to a method for controlling the pressure supplied by a CPAP device. The method comprises repeated measurement of a respiratory air flow during operation of the device and determining at least one respiratory event from the measured time-dependent behavior of the respiratory flow, the respiratory event representing an indication that the pressure supplied by the CPAP device is too low. Furthermore, the method comprises a slow, quasi ramp-like lowering of the pressure supplied by the CPAP device as long as no respiratory event is detected. Furthermore, the invention relates to a CPAP device for carrying out such a method and to a storage medium with a corresponding program.
