摘要: Systems and methods for one-touch ventilation mode are disclosed. In examples, settings for a medical ventilator are determined and delivered to a patient with a minimum of one input parameter. The one-touch ventilation mode may reference or apply one or more respiratory mechanics planes to determine desired ventilation parameters. In an example, the input parameter may be mapped to initial ventilation settings on a respiratory mechanics plane. During ventilation delivered according to the initial ventilation settings, ventilation data may be obtained. Based on the ventilation data, one or more ventilation strategies may be implemented, including breath type strategy, alarming strategy, triggering/cycling strategy, and PEEP strategy. Updated ventilation settings may be determined based on the ventilation data and/or the ventilation strategy.

摘要: Systems and methods for model-driven system integration on a ventilator comprise a modeled exhalation flow. Ventilator flow sensors contain components that are easily damaged or impacted and have high rates of failure. Knowledge failure frequency and type may help determine when to replace, clean, or calibrate a flow sensor. A modeled exhalation flow may be trained for a ventilator. Additionally, the modeled exhalation flow may be compared to a flow sensor flow to determine a specific failure. Additionally or alternatively, the modeled exhalation flow may supplement, weight, or replace a faulty flow sensor measurement. These systems and methods may assist in identifying an inaccurate flow sensor measurement and/or providing a more accurate modeled flow estimate, thus increasing accuracy in patient-ventilator interactions.

摘要: A humidifier, for a ventilation system, that includes an atomizer configured to deliver water droplets into a flow of breathing gases and a heating element configured to vaporize the water droplets emitted from the atomizer. The humidifier may be configured to set a target inhalation gas temperature based on internal temperature of a patient. Further, based on inspiratory flow and humidity data about breathing gases upstream of the atomizer of the humidifier, the humidifier may calculate and deliver an amount of water in one or more bursts of atomized water. Based on the target inhalation gas temperature, the humidifier may control a temperature of the heating element.

摘要: Systems and methods for monitoring delivered interface pressure comprise measuring inhalation and exhalation data to determine a virtual delivered interface pressure by a ventilator. While air pressure delivered to a patient through NIV or HFO therapy is important to patient comfort, ventilators only directly measure inhalation and exhalation data without direct measurements of delivered interface pressure. Knowledge of the delivered interface pressure may allow clinicians to more quickly titrate inhalation flow and exhalation pressure without sacrificing patient comfort. Additionally, knowledge of the delivered interface pressure in breathing circuits with high leak rates may reduce nuisance alarms that often sound when a delivered interface pressure is unknown. Associating delivered interface pressure with adjustable inhalation and exhalation parameters may allow continued monitoring of delivered interface pressure in addition to keeping delivered interface pressure within a desired range, thus optimizing patient-ventilator interaction.

摘要: Systems and methods for detecting respiratory mechanics of a patient during mechanical ventilation. An example ventilator implemented method includes receiving pressure and flow measurements of breathing gas. Based on the measurements, the ventilator generates values for a derivative of an estimate of intrapleural pressure (Psync) of the patient, and the ventilator determines a rate of change of the generated Psync values over a portion of an expiratory phase of a breathing cycle. Based on the determined rate of change, the ventilator selects at least one of a triggering mode or a setting for ventilation, and the ventilator controls ventilation of the patient based on the selected triggering mode and/or the setting for ventilation.

摘要: Systems and methods for detecting extubation of an endotracheal tube (ETT) are described. Extubation of the ETT can be identified by comparing to a threshold, a difference between a determined first volume of breathing gas during a first inspiratory period to a determined second volume of breathing gas during a second inspiratory period. If the difference exceeds the threshold, an alarm can be activated indicating extubation. Extubation detection may also be based on a difference between inspiratory pressures during separate inspiratory periods. Partial extubation and full extubation may also be discerned. Further, extubation of an ETT may be detected without the use of an exhalation flow sensor.
