A gas delivery conduit adapted for fluidly connecting to a respiratory gases delivery system in a high flow therapy system. In one embodiment, a nasal cannula includes a base portion defining a first therapeutic gas passageway, a nozzle disposed adjacent the base portion and defining a second therapeutic gas passageway, the first passageway being in gaseous communication with the second passageway and a conduit configured to facilitate sensing that has an inlet side that is independent of and axially spaced apart from an outlet side of the nozzle. The conduit inlet side can extend beyond the nozzle outlet side of the nasal cannula. Additionally, the nasal cannula has a feature adapted to prevent one of the conduit and the nozzle from creating a seal with a user's rare and a feature adapted to prevent one of the conduit and the nozzle from creating a seal with a user's nare.

Devices and methods for allowing for improved assisted ventilation of a patient. The methods and devices provide a number of benefits over conventional approaches for assisted ventilation. For example, the methods and devices described herein permit blind insertion of a device that can allow ventilation regardless of whether the device is positioned within a trachea or an esophagus.

Systems and methods for measurement of end tidal carbon dioxide, including a device having a body and a tubular gas line. The body is adapted to be attached to a patient airway and has a first gas line securing portion which has an aperture through it and is adapted to secure the gas line to the body. The tubular gas line is secured in the aperture. The tubular gas line has a proximal portion extending from a proximal end of the aperture and has a proximal end which is adapted to be connected to an end tidal CO2 monitor. The tubular gas line also has a distal portion extending from a distal end of the aperture and having a distal end which provides an inlet for end tidal CO2 exhaled by a patient.

A patient treatment system includes a ventilation bag, and a monitoring device which is configured so as to be connectable to the ventilation bag. The monitoring device measures the pulse rate derived from the heart rate of a neonate, from signals of ECG electrodes which are connected to the monitoring device. In a case where an abnormality of measurement information of the pulse rate is detected, the monitoring device notifies of first information prompting ventilation by the ventilation bag.

Various embodiments are described herein for a controller for controlling the operation of a breathing assistance device that provides breathing assistance to a user. The controller comprises a processor that generates a respiratory index value that is determined during a current monitoring time period to detect a respiratory failure, or predict the respiratory failure when at least one PSG signal is measured. The respiratory index value is compared to a threshold to determine if the control signal needs to be updated to reduce or eliminate respiratory failure that the user is currently experiencing or to prevent a predicted respiratory failure from occurring.

The disclosed system receives various physiological as well as physical information concerning a patient, and operational data from a ventilation device and medication delivery device, and provides the physiological and physical information, together with the operational data, to a neural network configured to analyze the information and data. The system receives, from the neural network, an assessment classification of the patient corresponding to at least one of a pain assessment, a sepsis assessment, and a delirium assessment of the patient based on providing to the neural network the determined physiological state of the patient, the determined physical state of the patient, the determined operational mode of the ventilator, the medication delivery information, and the received diagnostic information for the patient, and adjusts, based on the assessment classification, a ventilation parameter that influences the operational mode of a ventilator providing ventilation to the patient.
