A respiratory system includes a first patient interface for delivery of a flow of gases to a patient, a second patient interface for delivery of a second flow of gases to the patient, and a device that switches the system between a first respiratory mode and a second respiratory mode. In the first respiratory mode, the flow of gases are delivered to an outlet of the first patient interface when the second patient interface is absent from the patient. In the second respiratory mode the device reduces or stops delivery of the first flow of gases to the outlet of the first patient interface when the second patient interface is located together with the first patient interface upon the patient.

User interface and system for supplying gases to an airway

A pressure regulating or pressure relief device comprises an inlet and an outlet chamber with an outlet. The inlet is in fluid communication with the outlet chamber. A valve seat is located between the inlet and the outlet. A valve member is biased to seal against the valve seat, and displaces from the valve seat by an inlet pressure at the inlet increasing above a pressure threshold to allow a flow of gases from the inlet to the outlet via the outlet chamber. The flow of gases through the outlet causes an outlet pressure in the outlet chamber to act on the valve member together with the inlet pressure to displace the valve member from the valve seat.

Pressure regulating valve

This invention relates to, among other embodiments, methods and apparatus/systems for controlling gases delivery to a patient, such as via a patient interface. Such methods comprising receiving an input relating to either a patient's breathing phase and/or another patient parameter, controlling a flow of gases to be delivered to the patient and the inclusion in said flow of gases of a supplementary gas, wherein the amount of supplementary gas provided to the patient is substantially synchronized with respect to the patient's breathing phase and/or another patient parameter.

Apparatus for controlling gas delivery to a patient

The invention relates to a respiratory system comprising a first patient interface for delivery of a first flow of gases to a patient, a second patient interface for delivery of a second flow of gases to the patient, and a device and/or sensing arrangement that is configure to facilitate a switching of the system between a first respiratory mode where the device allowing delivery of the first flow of gases to an outlet of the first patient interface when the second patient interface is absent from the patient, and a second respiratory mode where the device reducing or stopping delivery of the first flow of gases to the outlet of the first patient interface when the second patient interface is located together with the first patient interface upon the patient.

Described is an apparatus for oxygenation and/or CO2 clearance of a patient, comprising: a flow source or a connection for a flow source for providing a gas flow, a gas flow modulator, a controller to control the gas flow, wherein the controller is operable to: receive input relating to heart activity and/or trachea gas flow of the patient, and control the gas flow modulator to provide a varying gas flow with one or more oscillating components with a frequency or frequencies based on the heart activity and/or trachea flow of the patient.

Methods and apparatus for oxygenation and/or CO2 removal

A method of determining a duration of safe apnoea. Information is obtained relating to a respiratory indicator, and a duration of safe apnoea is determined from the obtained information. A respiratory therapy system has one or more patient interfaces. A processor is configured to determine a duration of safe apnoea based on obtained information relating to a respiratory indicator.

Flow therapy system and method

An apparatus for oxygenation and/or CO2 clearance of a patient. The apparatus comprising: a flow source or a connection for a flow source for providing a gas flow, a gas flow modulator, a controller to control the gas flow. The controller is operable to: receive input relating to heart activity and/or trachea gas flow of the patient, and control the gas flow modulator to provide a varying gas flow with at least two oscillating components. One oscillating component has a frequency based on the heart activity and/or trachea flow of the patient. One oscillating component has a frequency to: promote bulk gas flow movement, or promote mixing.

This invention relates to a method or system for providing an indication or establishment of airway patency of a patient comprising monitoring of at least one targeted gas (e.g. CO2, N2 or may be other gases capable of being detected, monitored, and measured) that is being expired or being expelled from an airway of a patient (e.g. an apnoeic or non-spontaneously breathing patient), and based on measurements of the at least one targeted gas for a period of time, providing an indicator as to an output of the measurements of the at least one targeted gas for the period of time, or a determination as to airway patency, or a determination as to a location of a blockage or obstruction in the airway, or combinations of these.
