The present disclosure relates, in some embodiments, to devices, systems, and/or methods for collecting, processing, and/or displaying stroke volume and/or cardiac output data. For example, a device for assessing changes in cardiac output and/or stroke volume of a subject receiving airway support may comprise a processor; an airway sensor in communication with the processor, wherein the airway sensor is configured and arranged to sense pressure in the subject's airway, lungs, and/or intrapleural space over time; a blood volume sensor in communication with the processor, wherein the blood volume sensor is configured and arranged to sense pulsatile volume of blood in a tissue of the subject over time; and a display configured and arranged to display a representative of an airway pressure, a pulsatile blood volume, a photoplethysmogram, a photoplethysmogram ratio, the determined cardiac output and/or stroke volume, or combinations thereof. A method of assessing changes in cardiac output or stroke volume of a subject receiving airway support from a breathing assistance system may comprise sensing pressure in the subject's airway as a function of time, sensing pulsatile volume of blood in a tissue of the subject as a function of time, producing a photoplethysmogram from the sensed pulsatile volume, determining the ratio of the amplitude of the photoplethysmogram during inhalation to the amplitude of the photoplethysmogram during exhalation, and determining the change in cardiac output or stroke volume of the subject using the determined ratio.

Method for determining hemodynamic effects

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

A system and method for conserving oxygen in a breathing assistance device are disclosed. A method may include delivering breathable gas with a first average oxygen concentration during a first portion of an inhalation phase for a patient. The method may also include delivering breathable gas with a second average oxygen concentration during a second portion of an inhalation phase for a patient.

Systems and methods for conserving oxygen in a breathing assistance device

A medical device may include a patient interface for use in a breathing assistance system, an electronic device coupled to the patient interface, and one or more electrical conductors at least partially integrated with the patient interface. The patient interface may include a connection end configured for receiving gas communicated by a gas delivery apparatus, and a patient end configured for insertion into or more breathing passageways of a patient. The one or more electrical conductors at least partially integrated with the patient interface may be capable of facilitating communication of electrical signals between the electronic device and the gas delivery apparatus when the patient interface is communicatively coupled to the gas delivery apparatus.

Patient interface having an integrated system for communicating data to a 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

This disclosure describes systems and methods for managing the ventilation of a patient being ventilated by a medical ventilator. The disclosure describes a novel approach of displaying ventilator information integrated with oximeter information. The disclosure further describes a novel approach of alarming based on the integration of ventilator information with oximeter information.

Medical ventilator with integrated oximeter data

A medical device may include a gas delivery apparatus, a patient interface, a connection system, and an electrical circuit. The gas delivery apparatus may be configured to deliver gas to a patient. The patient interface may be configured to interface with the patient to deliver gas communicated by the gas delivery apparatus to the patient. The connection system may be configured to communicate gas from the gas delivery apparatus to the patient interface. The electrical circuit may be configured to communicate electrical signals between the patient interface and the gas delivery apparatus, and may including one or more first electrical conductors at least partially integral with the patient interface and one or more second electrical conductors at least partially integral with the connection system.

Breathing assistance system having integrated electrical conductors communicating data

A breathing assistance system may include a patient interface configured to interface with a patient to communicate gas received from a gas delivery apparatus to the patient, and a securing system configured to secure the patient interface against the patient's face. The securing system may include one or more walls forming a generally tubular structure open at least at one end. At least a portion of the one or more walls may be elastic such that at least a portion of the generally tubular structure can be stretched over the patient's head.
