A water reservoir dock forms a cavity configured to partially receive the water reservoir. The water reservoir lid includes a protrusion and the water reservoir dock includes a recess configured to releasably engage one another to secure the water reservoir to the water reservoir dock.

A respiratory humidification system includes a humidifier that is capable of electronic communication with one or more other components of the system thereby permitting transfer of data or control signals between the humidifier and other components of the system. In some systems, a flow generator, such as a ventilator, is provided to supply a flow of breathing gas. The humidifier and the flow generator are capable of electronic communication with one another. In some arrangements, an operating mode or parameter of the humidifier to be set or confirmed by the flow generator, either automatically or manually through a user interface of the flow generator. The humidifier can also utilize data provided by the flow generator or other system component, such as an incubator, to set or confirm an operating mode or parameter of the humidifier. In some arrangements, a user interface of the humidifier can display data from another system component, such as a nebulizer or pulse oximeter.

Respiratory systems with a flow generator can provide bubble CPAP therapy by controlling the pressure of a flow of gas delivered to a patient. The controller of the respiratory system can control a motor speed of its flow generator so as to control the pressure of the flow of gas. The controller can also detect presence of bubbling and/or possible leaks in the gas pathway of the system. The respiratory system can include a high flow respiratory system.

A breathing assistance system for delivering a stream of heated, humidified gases to a user, comprising a humidifier unit which holds and heats a volume of water, and which in use receives a flow of gases from a gases source via an inlet port, the flow of gases passing through the humidifier and exiting via an exit port, the system further having a temperature sensor which measures the temperature of the gases exiting the humidifier unit, an ambient temperature sensor which measures the temperature of gases before they enter the humidifier unit, and a flow sensor which measures the flow rate of the gases stream, the system also having a controller which receives data from the temperature and flow sensors, and which determines a control output in response, the control output adjusting the power to the humidifier unit to achieve a desired output at the humidifier unit exit port.

Various control methods can indirectly determine incorrect connections between components in a respiratory therapy system. For example, incorrect connections can occur between a patient interface, a humidifier and/or a gases source. The methods can indirectly detect if reverse flow conditions or other error conditions exist. A reverse flow condition can occur when gases flows in a direction different from an intended direction of flow. The methods can be implemented at the humidifier side, at the gases source side, or both.

A heated conduit is configured to be connected to and receive pressurized breathable gas from a respiratory unit. The heated conduit includes a first cuff configured to be attached to the respiratory unit, the first cuff comprising a tubular air inlet portion that is configured to receive the pressurized breathable gas and an electrical connector portion that is adjacent to the tubular air inlet portion and comprises three electrical terminals. The three electrical terminals are configured to engage an electrical connector of the respiratory unit. A grouping of wires are supported within a helical rib of a flexible tube portion. The grouping of wires includes a pair of heating wires configured to generate heat and a signal wire configured to carry the signal that is output by a sensing device. Each of the heating wires and the signal wire is connected to a corresponding one of the three electrical terminals of the electrical connector portion of the first cuff.

Dew point sensor system contains-a controller with dew point calculator, ambient temperature sensor, air pathway, heater plate, external wire. Ambient temperature sensor generates ambient temperature data, operatively-connected to controller. Air pathway contains blower within air pathway, air flow sensor within air pathway, liquid reservoir operatively-connected to air pathway, and component may be air pathway temperature sensor and/or breathing circuit heating element. Blower causes air to move in air pathway (52), air flow sensor generates air flow data about air moving in air pathway. The heater plate contains heater plate temperature sensor, and heater plate temperature sensor generates heater plate temperature data. External wire is operatively-connected to controller and component. Ambient temperature sensor located on the external wire. Heater plate and the heater plate temperature sensor operatively-connected to the controller receiving ambient temperature data, air flow data, and heater plate temperature data to calculate target heater plate temperature, based on dew point temperature.

Systems and methods can determine whether a patient is attached to a respiratory device (such as to via a patient interface) by analyzing a flow parameter signal in the time domain. Additionally, the processes can classify the patient attachment status into one of the four categories: detached, attaching, attached, or detaching. The system can include a non-sealed patient interface, such as a nasal cannula in a nasal high flow therapy, or any other patient interfaces. Data of the patient's use of the respiratory system can provide therapy compliance and long-term trend of use information and/or progress in the patient's respiratory functions and/or other physiological functions.

A respiratory therapy system for providing continuous positive air pressure (CPAP) to a patient may include a flow generator for generating a supply of breathable gas, a sensor to measure a physical quantity while the breathable gas is supplied, and a computing device. The computing device may be configured to: receive sensor data that is based on measured physical property of the supply of breathable gas; control the flow generator to adjust a property of the supply of breathable gas; display a question and a plurality of selectable responses; receive a first input selecting one of the selectable responses; and display a coaching response corresponding to the selected response.
