Abstract: According to an aspect, there is provided a cannula for use in high flow nasal therapy, comprising: a first tube for directing a first fluid from a nasal cavity of a subject to a location outside of the subject; a second tube for directing a second fluid from a supply of the second fluid to the nasal cavity of the subject; a flow sensor located within the first tube, the flow sensor configured to measure a flow rate of the first fluid moving through the first tube; and a humidity sensor located within the first tube, the humidity sensor configured to measure a humidity of the first fluid moving through the first tube; wherein the measured flow rate and the measured humidity are to be used by a processor to control a humidifier to adjust a humidity of the second fluid to be supplied to the subject.

Abstract: 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.

Abstract: A therapy system has a nasal cannula patient interface configured to deliver gas to a nasal cavity of a patient and a delivery system for delivering oxygen-enriched breathing gas, comprising air and enrichment oxygen, to the patient interface. A sensor is provided allowing arterial partial pressure of CO2, PaCO2 to be measured or estimated thereby to generate capnograph data, A parameter is determined from the capnograph data which is representative of CO2 washout, and the total flow rate, the oxygen flow rate or the air flow rate of the breathing gas delivered by the delivery system are iteratively adjusted while monitoring the determined parameter. A value of total flow rate, oxygen flow rate or air flow rate is used which maximizes CO2 washout or achieves a desired level of CO2 washout.

Abstract: The invention provides a positive airway pressure therapy system comprising a positive pressure generation unit, adapted to generate a positive pressure airflow for provision to a subject, and an oscillatory pressure generation unit adapted to modulate the positive pressure airflow at a modulation frequency thereby imparting a frequency component to the positive pressure air flow. The oscillatory pressure generation unit is adapted to modulate the airflow during an exhalation phase of a breathing cycle of the subject.

Abstract: Provided are concepts for generating an indicator of chronic obstructive pulmonary disease (COPD) in a subject. In particular, data from a plurality of sensors, including a pressure sensor, an airflow sensor, and a CO2 concentration sensor is captured from the breath of the subject received by a mouthpiece. The sensor data is then utilised by a processing unit to generate an indicator of COPD in the subject. By utilising airway pressure, airway flow rate and expiratory CO2 concentration data, an accurate indicator of the presence and/or stage of COPD may be obtained.

Abstract: A system is for analyzing physical characteristics of mucus, in particular during patient respiratory support using a ventilator. A ventilation waveform is sensed and analyzed and an estimate of, or a change in, at least one mucus characteristic can then be determined.
