Systems and methods for collecting breathing gas properties via a medical ventilatory filter and wirelessly transmitting the data to another device. For example, the filter includes a first housing enclosing filtration media for filtering breathing gases flowing through the filter, the first housing defining a first port and a second port exposed to the breathing gases; and a sensor assembly. The sensor assembly includes a first sensor coupled to the first port, the first sensor configured to capture measurement data for a first gas property of breathing gases flowing through the filter; a second sensor coupled to the second port, the second sensor configured to capture measurement data for a first gas property of the breathing gases flowing through the filter; and a second housing. The second housing includes a processor and communication circuitry operative to wirelessly communicate the sensor data to a computing device located remotely from the filter.

A breathing assistance apparatus and method of controlling a breathing assistance apparatus is disclosed. Particularly, the breathing assistance apparatus is controlled such that it has a drying cycle to enable drying of the tubing that supplies gases to a user and prevent the harboring of pathogens within the tube. The drying cycle is preferably operated automatically by internal controllers in the apparatus. However, it may be manually activated by pressing a button on the apparatus. The drying cycle is preferably activated at the end of a user's treatment session.

The gases temperature supplied to a patient when the patient is undergoing treatment such as oxygen therapy or positive pressure treatment for conditions such as Obstructive Sleep Apnea (OSA) or Chronic Obstructive Pulmonary Disease (COPD) is often measured for safety and to enable controlling of the humidity delivered to the patient. The invention disclosed is related to measurement of properties, particularly temperature (thermistor), of gases flowing through a heated tube, supplying gases to a patient, which utilises the heating wire within the tube.

The present invention provides for an improved method of determining a water out condition in a humidified gases supply apparatus. The method includes a two step process including a primary determination of a water out condition and a secondary determination of a water out condition. This primary determination is made during observation of the normal operation of the apparatus. During the secondary determination the method takes temporary control over the humidifying part of the apparatus. The secondary determination confirms or contradicts the primary determination.

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 personal entertainment respiratory apparatus provides air to a user to provide a fully immersive entertainment experience. The personal entertainment system may comprise a flow generator for providing the flow of air. A personal spatial respiratory interface may be coupled to the flow generator. The personal spatial respiratory interface may comprise an outlet for the flow generator. The personal spatial respiratory interface may further be configured to direct the flow of air within an ambient breathing proximity of a user. The personal entertainment respiratory apparatus may further comprise a controller and a sensory particle dispenser. The controller and sensory particle dispenser may be configured to selectively activate release of a sensory particle from the dispenser into the directed flow of air in response to an entertainment triggering signal.

A vent adaptor for a for a respiratory pressure therapy (RPT) system, the vent adaptor comprising: a vent assembly comprising: a vent housing defining a central orifice for the flow of pressurized gas to pass through the vent assembly from the delivery conduit to the patient interface, the vent housing having an annular surface around the central orifice, and the annular surface having a plurality of holes to discharge pressurized gas to atmosphere; and a membrane positioned adjacent to the annular surface; a heat and moisture exchanger (HME); and a diffusing member.

A gases humidifier comprising: a gases inlet and an outlet, a removable humidification chamber cartridge with a heater source adapted to vaporize fluid; and a metering arrangement adapted to connect to and transfer fluid from a fluid supply to the humidification chamber.

A newborn respiration monitoring system includes a flow sensor that measures a gas flow and a CO.sub.2 sensor that measures a CO.sub.2 within the breathing circuit for an infant. The system further includes a resuscitation module executable on a processor of a computing system to receive the flow measurement and the CO.sub.2 measurement and determine respiratory information for the infant. A digital display is communicatively connected to the computing system and displays the respiratory information.
