This disclosure describes systems and methods for providing drive pressure ventilation of a patient. The disclosure describes a novel breath type that provides a spontaneous breath type that allows for the calculation of drive pressure that does not require invasive monitoring.

Systems and methods for drive pressure spontaneous ventilation

A mechanical ventilator is provided that includes a dashboard display identifying a patient's current ventilatory status within a global or universal ventilatory mechanics map. This dashboard display is dynamically updated with the patient's condition, and shows trends in the patient's ventilation over time. The map identifies suggested safe and unsafe regions of ventilation for the patient, and the ventilator can display informational texts, trigger auditory and/or visual alarms, and transmit alarm communications in response to determining that the patient is approaching or has entered an unsafe region.

Systems and methods for ventilation of patients

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.

Detection of expiratory airflow limitation in ventilated patient

This disclosure describes systems and methods for providing drive pressure ventilation of a patient. The disclosure describes a novel breath type that provides a spontaneous breath type that allows for the calculation of drive pressure that does not require invasive monitoring, where drive pressure is the pressure applied to the lungs that causes them to inflate during mechanical ventilation.

A breathing support system is provided. The system may include a breathing support device configured to deliver gas to a patient and a display device associated with the breathing support device. The display device may be configured to display a work of breathing graphic indicating one or more work of breathing measures regarding the patient's breathing.

Work of breathing display for a ventilation system

An exhalation assembly that controls the pressure of exhaled gas in a ventilation system is described. The exhalation assembly includes a filter body and a condensate trap. Additionally, a filter/trap module that includes a filter body and a condensate trap is also described.

Exhalation valve assembly with integral flow sensor

An exhalation value assembly that controls the pressure of exhaled gas in a ventilation system is described. The exhalation valve assembly includes a valve module, removable for cleaning or disposal, a filter module, a flow meter and a condensate trap. Additionally, a filter/trap module that introduces a filter and a condensate trap into the exhalation flow path is described.

This disclosure describes improved systems and methods for efficiently configuring respiratory settings and/or parameters in a ventilatory system. Specifically, the present methods and user interface provide an efficient and consistent means for configuring ventilatory settings for a new patient. Specifically, the ventilator may be preconfigured with appropriate parameter settings based on an institution-specific protocol, a physician-specific protocol, or other suitable protocol or specification. Indeed, the present disclosure provides an institution and/or physician with increased control over routine ventilatory settings by pre-configuring the ventilator with these routine settings. Further, the present disclosure provides increased assurance as to the consistency of the routine ventilatory settings by eliminating repeated data entry by clinicians, decreasing the chances of error.

Quick initiation of respiratory support via a ventilator user interface

The invention is directed to a ventilation control system for controlling the ventilation of a patient. The ventilation control system utilizes a user-friendly user interface for the display of patient data and ventilator status, as well as for entering values for ventilation settings to be used to control the ventilator.

Graphic user interface for a patient ventilator

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.

Method for ventilation

This disclosure describes systems and methods for monitoring a patient on a ventilator-oximeter system. The disclosure describes a novel approach determining if the oximeter and the ventilator are attached to the same patient and if not providing a warning.

Methods for validating patient identity

A breathing support system is provided. The system may include a breathing support device configured to deliver gas to a patient and a display device associated with the breathing support device. The display device may be configured to display a graphic indicating one or more measures regarding the patient's work of breathing.

The invention is directed to a ventilation control system for controlling the ventilation of a patient. The ventilation control system utilizes a user-friendly user interface for the display of patient data and ventilator status. The user interface includes a graphic representation of a breath cycle that displays the breath cycle currently being ventilated, and is also responsive to changes in ventilation settings to assist the user in evaluation the effect of those changes on the ventilator strategy before the changes are implemented.
