    摘要: This disclosure describes improved systems and methods for displaying respiratory data to a clinician in a ventilatory system. Respiratory data may be displayed by any number of suitable means, for example, via appropriate graphs, diagrams, charts, waveforms, and other graphic displays. The disclosure describes novel systems and methods for determining and displaying ineffective patient inspiratory or expiratory efforts or missed breaths in a manner easily deciphered by a clinician.

    摘要: This disclosure describes systems and methods for monitoring and evaluating data associated with ventilatory parameters to detect expiratory airflow limitation in a ventilated patient. For example, a ventilator may monitor flow and/or pressure during ventilation of the patient. Based on the flow and/or pressure measurements, or ventilatory data derived therefrom, the ventilator may calculate expiratory resistance. Moreover, the ventilator may trend expiratory resistance over time to produce an expiratory resistance waveform. In embodiments, the ventilator may calculate the slope of the expiratory resistance waveform during an initial part of exhalation. If the slope of the expiratory resistance waveform during the initial part of exhalation breaches a defined slope threshold, the ventilator may determine that the patient exhibits expiratory airflow limitation.

    摘要: The disclosure describes a method for automatically initiating ventilation, controlling ventilation, transitioning a ventilator to subject controlled ventilation, and weaning a subject from ventilation. The disclosure describes that the method for automatically initiating ventilation includes inputting a physical characteristic of the subject into a ventilator. The physical characteristic may be ideal body weight, height, or age. Based on the inputted physical characteristic, one or more ventilation parameters are calculated. The disclosure describes initiating ventilation based on the calculated parameters. During ventilation at least one physiological parameter of the subject is monitored. At least one ventilation parameter may be adjusted based on the monitoring of the physiological parameters and the inputted physical characteristic.
