  • Medical ventilator triggering and cycling method and mechanism
    Patent number: 7000612
    Abstract: A medical ventilator system and method that triggers, cycles, or both based on patient effort, which is determined from cross-correlating patient flow and patient pressure. The medical ventilator is also controlled such that sensitivity to a patient initiated trigger increases as the expiratory phase of the breathing cycle progresses. The present invention also provides adaptive adjustment of cycling criteria to optimize the cycling operation.
    Type: Grant
    Filed: November 24, 2004
    Date of Patent: February 21, 2006
    Assignee: RIC Investments, LLC.
    Inventors: Mehdi M. Jafari, Gardner J. Kimm, Karrie McGuigan
