  • Method for providing respiratory airway support pressure
    Patent number: 6240919
    Abstract: A method of supporting respiratory airways during ventilator-assisted respiration. The method includes applying two supplemental pressure supports. The first such supplemental pressure support includes applying pressure of a first magnitude upon initiation of and for the duration of an inspiratory phase. The second supplemental pressure support includes applying pressure of a second magnitude greater than the first magnitude of the first supplemental pressure support upon initiation of and for the duration of the expiratory phase. In this manner, full time pressure augmentation is applied to respiratory airways to thereby structurally support the airways and thus maintain in an open configuration the pathways in communication with lungs.
