Provided are concepts for controlling a high flow nasal therapy (HFNT) device used by a subject. In particular, physiological and movement parameter values of the subject are leveraged in order to generate a control signal for the HFNT device. These parameters may indicate an activity level of the subject, as well as the condition of the subject, providing information useful for setting appropriate operating conditions of the HFNT device. Thus, a means for automatically controlling a HFNT device based on needs of the subject may be provided, improving subject comfort during therapy, and ease of use of the HFT device.

According to an aspect, there is provided a ventilator system. The ventilator system comprises: a mouthpiece, to be received within a user's mouth, wherein the mouthpiece comprises: a passage for permitting a flow of gases through the mouthpiece between a first side of the passage to be inside the user's mouth and a second side of the passage to be outside the user's mouth; a passage adjustment component for selectively adjusting a flow area of the passage; and one or more sensors mounted on the mouthpiece, wherein the sensors comprise a pressure sensor configured to measure a pressure at the first side of the passage; and a controller configured to control: a flow rate and/or concentration of oxygen supplied to the user through a nasal cannula; a total flow rate of air and oxygen supplied through the nasal cannula; and/or the flow area of the passage, based on the pressure measured by the pressure sensor.

A gas humidifier can have a gas channel comprising an inlet and an outlet. A portion of the gas channel can have a region having a reduction in cross-sectional area relative to the portions of the gas channel outside of the region. A water conduit can extend from the region to a water reservoir. A heating element can heat water entering the region from the water conduit. Water vaporized using the heating element can join the flow of gases passing through the gas channel in use.

A reality system includes a display aimed at a retina, the display providing 3D images with different depth view points; a glass to selectably turn on or off view of an outside environment in front of the person's eye; a processor coupled to the camera and to the glass to selectably switch between augmented reality and virtual reality; and a wireless transceiver coupled to the transceiver to communicate with a remote processor.

A respiratory therapy system can have a flow generator adapted to provide gases to a patient. A gas passageway can be located in-line with the flow generator. The gas passageway can have a first portion adapted to receive a first gas and a second portion adapted to receive a second gas. The gas passageway can have a static mixer downstream of the first and second portions.

A system for improving cardiac output of a patient suffering from pulseless electrical activity or shock and yet displays myocardial wall motion including: a sensor to detect myocardial activity to determine the presence of residual left ventricular pump function having a contraction or ejection phase and a filling or relaxation phase, a device to prompt the application of or apply a compressive force repeatedly applied to the chest based on the sensed myocardial activity such that the compressive force is applied during at least some of the ejection phases and is ceased during at least some of the relaxation phases to permit residual cardiac filling, thereby enhancing cardiac output and organ perfusion.

A respiratory treatment apparatus (1) provides blood glucose monitoring and breathing control based on detected blood glucose information. In an example embodiment, a flow generator provides a flow of breathable gas at a pressure above atmospheric to a patient interface according to a pressure treatment control protocol such as a CPAP, APAP, bi-level CPAP, etc. A detector determines a blood glucose condition indicator with one or more sensors that are used to sense physiological information. In response to signals from the sensors, a controller, such as a digital signal processor, controls adjustments to the flow of breathable gas provided by the flow generator. The adjustments are determined by the controller based on the detected blood glucose indicator and/or changes thereto.

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.
