A load control system may control an electrical load in a space of a building based on one or more parameters regarding the physical condition of an occupant. The parameters may be gathered by one or more sensing devices. The sensing devices may be included in a mobile device. A system controller may receive the parameters and may automatically control the electrical loads in response to the parameters. The system controller may control the electrical load to attempt to adjust the physical condition of the occupant in response to the sensed parameters. The system controller may control the electrical load to provide an alert, an alarm, and/or a warning in response to the sensed parameters.

An exchanger conduit permits temperature and/or humidity conditioning of a gas for a patient respiratory interface. In an example embodiment, a conduit has a first channel and a second channel where the first channel is configured to conduct an inspiratory gas and the second channel configured to conduct an expiratory gas. An exchanger is positioned along the first channel and the second channel to separate the first channel and the second channel. The exchanger is configured to transfer a component (e.g., temperature or humidity) of the gas of the second channel to the gas of the first channel. In some embodiments, an optional flow resistor may be implemented to permit venting at pressures above atmospheric pressure so as to allow pressure stenting of a patient respiratory system without a substantial direct flow from a flow generator of respiratory treatment apparatus to the patient during patient expiration.

Systems and methods can determine respiratory rates of a patient using a respiratory device by performing one or more frequency analyses of a signal from the gases flow. The signal from the gases flow can be one that varies with the patient's breathing. 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. The respiratory system can also detect whether the patient has taken off the patient interface and/or whether the patient connected to the patient interface is talking or eating. Data of the patient's use of the respiratory system and the patient's respiratory rates 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 positive exhalation pressure device (1) is described. The device (1) comprises a housing (2) having an annular chamber (5), a chamber inlet (6) configured to permit air into the chamber, a chamber outlet (7) configured to permit air out of the chamber, and a mouthpiece (8) in fluid communication with the chamber inlet. A movable body such as a ball (3) is disposed in the housing within the annular chamber and configured to revolve around the annular chamber in response to flow of air through the chamber from the chamber inlet to the chamber outlet. The movable body is configured to at least partially block the chamber outlet as it revolves around the annular chamber causing cyclical fluctuations in airflow resistance.

Disclosed herein are novel designs of a medical tube for delivering a respiratory gas to a subject in respiratory therapy, wherein the medical tube is in fluid connection with a user interface and a respiratory device. The medical tube has a tubular body, a first rib helically extending along the outer surface of the tubular body, and optionally, a second rib disposed next to the first rib, and optionally, a membrane encapsulating the first and/or second ribs thereby creating a helical space along the outer surface of the tubular body. In some embodiments, the first rib has a lumen and at least one wire disposed outside the lumen. In other embodiments, the first rib is free of any lumen and includes one or more wires extended therethrough. The lumen of the first rib or the helical space created by membrane encapsulation is configured to monitor the temperature, humidity, flow rate or pressure of the respiratory gas or an exhaled/inhaled gas of a subject.

Breathing tube assemblies for use with a respiratory therapy device, such as a continuous positive airway pressure (CPAP) device, includes an elbow that permits adjustment of a position of the breathing tube assembly relative to the respiratory therapy device. In some arrangements, the breathing tube assembly includes a breathing tube and a swivel elbow. The breathing tube is rotationally fixed relative to the respiratory therapy device and the swivel elbow rotatable relative to the breathing tube. In other arrangements, the breathing tube assembly includes an elbow that can be coupled to the respiratory therapy device in one of several possible positions.

In an embodiment, a connector or connector assembly for attaching a nasal cannula with a gas delivery hose includes a sensor port for a sensor probe positioned near an end of a nasal cannula, which can allow the sensor probe to be placed closer to the patient's nostrils than previous connector parts allowed. The connector can be configured to advantageously allow the nasal cannula to rotate relative to the gas delivery hose, thereby allowing a patient or healthcare provider to untangle or otherwise straighten the hose or the cannula. The connector assembly can be configured to automatically align locking protrusions on a first component with locking recesses on a second component, where insertion of the second component within the first component causes the second component to rotate relative to the first component, thereby aligning the locking protrusions with associated locking recesses.

Introduced are methods and systems for an adjustable bed device configured to: gather biological signals associated with multiple users, such as heart rate, breathing rate, or temperature; analyze the gathered human biological signals; and heat or cool a bed based on the analysis.

The present invention relates to a tub configured to receive a volume of liquid for a humidifier, comprising at least one plastic component and at least one metal component, which together form a space for receiving said volume of liquid, wherein the at least one metal component and the at least one plastic component are attached to each other by means of a silicone seal. Furthermore, the invention relates to method for manufacturing a tub for a humidifier.

The principles and embodiments of the present invention relate to methods and systems for safely providing NO to a recipient for inhalation therapy. There are many potential safety issues that may arise from using a reactor cartridge that converts NO.sub.2 to NO, including exhaustion of consumable reactants of the cartridge reactor. Accordingly, various embodiments of the present invention provide systems and methods of determining the remaining useful life of a NO.sub.2-to-NO reactor cartridge and/or a breakthrough of NO.sub.2, and providing an indication of the remaining useful life and/or breakthrough.
