  • Publication number: 20240165351
    Abstract: The present technology is directed to systems and methods for measuring patient lung pressure in a patient during pressure-controlled or volume-controlled ventilation. For example, the present technology includes operating a ventilator blower at a first speed during an inspiratory phase of a breath to direct gas from the ventilator to the patient along a flow path, and, after the inspiratory phase and before an expiratory phase of the breath, operating the blower at a second speed less than the first speed to achieve a zero-flow state in the flow path during which gas neither flows into nor out of the patient's lungs. During the zero-flow state, the pressure in the flow path is equal or at least approximately equal to the patient lung pressure. Accordingly, pressure can be measured at any position along the flow path during the zero-flow state to determine patient lung pressure.

  • Patent number: 10238823
    Abstract: A ventilator includes first and second pathways, a conduit and a controller. The first pathway (120) is configured to supply a first gas and the second pathway (140) is configured to supply a second gas, where the second gas is mixed with the first gas to produce mixed gas having a predetermined percentage of the second gas. The conduit (166) is configured to provide the mixed gas from the first and second pathways to an access port during an inspiratory phase, and to provide discharged gas from the access port to the first pathway during an expiratory phase. The controller (180) is configured to delay supply of the second gas from the second pathway for a delay time in order to maintain the predetermined percentage of the second gas in the mixed gas provided to the access port during a subsequent inspiratory phase.

  • Patent number: 9937308
    Abstract: A pressurized flow of breathable gas is delivered to the airway of a subject in accordance with a therapy regimen. The therapy regimen may be designed to maintain oxygenation of the subject. The therapy regimen dictates levels of fraction of inspired oxygen and/or positive end expiratory pressure to maintain a therapeutically beneficial level of oxygenation in a feedback manner. Within the therapy regimen, changes made to fraction of inspired oxygen and/or positive end expiratory pressure automatically and dynamically are constrained by user configured constraints such as the maximum incremental change, amount of time between adjustments, or the maximum rate of change This may provide a level of customization of the automated control of the therapy regime for individual subjects.
