Patent number: 9913954Abstract: A method of providing pressure support to a patient that includes determining a measure associated with an inspiratory time of the patient during therapy, delivering a flow of breathing gas to the patient at an inspiratory positive airway pressure (IPAP) level during at least a portion of an inspiratory phase of the patient, delivering the flow of breathing gas to the patient at an expiratory positive airway pressure (EPAP) level that is less than the IPAP level during at least a portion of an expiratory phase of the patient, and automatically setting a rise time associated with a transition from the EPAP level to the IPAP level based on the measure associated with the inspiratory time of the patient. Also provided is a pressure support system adapted to perform the method.Type: GrantFiled: November 21, 2009Date of Patent: March 13, 2018Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Winslow Kevin Duff, Peter D.

Patent number: 9295794Abstract: The present invention describes systems and methods to provide variable flow oxygen therapy. An exemplary embodiment of the present invention provides a method of oxygen therapy involving delivering oxygen-enriched gas to a patient during a first portion of a breathing cycle at a first flow rate. Furthermore, the method of oxygen therapy involves delivering oxygen-enriched gas to the patient during a second portion of the breathing cycle at a second flow rate, where the second flow rate is greater than zero and less than the first flow rate.Type: GrantFiled: November 21, 2009Date of Patent: March 29, 2016Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Peter Bliss, Robert Murdoch, Robert Romano, Peter D.

Patent number: 8789528Abstract: A method of delivering a flow of gas to a patient's airway via a pressure generating system and a patient circuit. A controller receives a treatment set point from an input source and determines an adjusted treatment set point based on the treatment set point and a comfort feature function, which in one embodiment, is not based on a physiological condition of such a patient. In another embodiment, the controller provides a respiratory treatment therapy during a therapy session based on the treatment set point and the comfort feature, which is modified automatically during a therapy session without user intervention based on a comparison of the treatment set point to a treatment set point variable. The controller controls the operation of the pressure generating system based on the adjusted treatment set point or the combination of the treatment set point and the comfort feature.Type: GrantFiled: February 8, 2008Date of Patent: July 29, 2014Assignee: Ric Investments, LLCInventors: Duane H. Carter, Tim Dixon, Daniel A. Jonczak, Zachary Paul, Benjamin I. Shelly, Greg Matthews, Peter D. Hill, Andrew DeGuilio

Patent number: 6467477Abstract: A system and method for providing a therapeutic treatment, such as a flow of breathing gas, to a patient at variable treatment levels. A respiratory cycle monitor detects the patient's respiratory cycles and a control unit incrementally adjusts the treatment level from a first predetermined level to a second predetermined level over a first predetermined number of respiratory cycles. The amount of the incremental adjustment and the frequency of such adjustments over the course of the first predetermined number of respiratory cycles can be controlled to achieve a desired change in the therapeutic treatment over the course of the patient's respiration.Type: GrantFiled: March 15, 2000Date of Patent: October 22, 2002Assignee: Respironics, Inc.Inventors: John Frank, Peter D.
