The present invention provides systems, methods, and articles for stress reduction and sleep promotion. A stress reduction and sleep promotion system includes at least one remote device, at least one body sensor, and at least one remote server. In other embodiments, the stress reduction and sleep promotion system includes machine learning.

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.

Some embodiments provide a breathing assistance apparatus comprising a conduit for conveying gases therein, the conduit comprising circuitry. The circuitry may comprise at least one heater wire part to heat gases in the conduit, in use, and at least one sensor wire part comprising at least one sensor for monitoring a parameter of the gases in the conduit. There is also provided a controller to control provision of AC power or AC voltage to the heater wire part; and control selective reading of the sensor. The controller may be configured to read the sensor at or about a particular portion of the AC power waveform provided to the heater wire part.

A head-mounted respiratory assistance apparatus configured to provide a respiratory gases stream to a user. The head-mounted respiratory assistance has a main body securable to the head of a user and a blower unit that is operable to generate a pressurised gases stream from a supply of gases from the surrounding atmosphere. A patient interface is provided on the main body that has a gases inlet which is fluidly connected to the blower unit and which is configured to deliver the pressurised gases to the user's nose and/or mouth.

Provided is a system for operating a ventilator. The system includes a motorized proportional valve actuator including a stepper motor and an actuator. The actuator is connected to the stepper motor and configured to output pressurized air by controlling a pressure on a valve diaphragm. A conduit provides for fluid communication of the pressurized air to a breathing apparatus. A sensor arrangement is in fluid communication with the conduit between the at least one motorized proportional valve actuator and the breathing apparatus. The sensor arrangement includes: (i) an intake manifold configured to output a restricted flow of air from the pressurized air transported in the conduit, and (ii) a sensor device in fluid communication with an outlet of the intake manifold, the sensor device configured to measure an air pressure of the conduit based on the restricted flow of air.

A mask 100 configured to substantially surround an opening of a patient's airway. The mask has a mask body 101 comprising a filter 103 configured to filter a fluid from a patient facing side of the mask to a non-patient facing side 105 of the mask, wherein the non-patient facing side faces an ambient environment AE. The mask has an interfacing feature 121 configured to, in use, interface with a patient interface 10100, 10100 provided on the patient 10020.

A micro-environment controllable temperature and humidity system evaluates heat and humidity comfort level of textiles. The system includes a bed-shaped partitioned platform having one or more non-temperature and humidity-controllable sections and one or more temperature and humidity controllable sections. One or more temperature and humidity control machine is in communication with the one or more temperature and humidity control sections for supplying air with a pre-set temperature and humidity. A central controller electrically is connected to the one or more temperature and humidity control machines. The micro-environment controllable temperature and humidity system can perform partitioned control on the temperature and humidity in a micro-environment during sleep, and is used for studying the influence of the temperature and humidity on the comfort level of different regions of a subject.

Methods and systems to treat Cheyne-Stokes respiration (CSR) and/or central sleep apnea (CSA) include monitoring retrograde breathing and detecting respiratory events. Based on the occurrences of certain respiratory events, a target volume of rebreathing is adjusted to reduce arousals as well as CSR/CSA.

The present disclosure pertains to a system and method for controlling insufflation pressure during inexsufflation of a subject. The system inexsufflates the subject such that tidal flow and/or tidal volume are monitored during insufflation, and insufflation pressure is adjusted to maintain the flow rate of the pressurized flow of breathable gas until a target tidal volume is reached for the insufflation. When the target tidal volume has substantially been reached, the system is causes gas to be evacuated from the airway of the subject. This may provide for more precise, customized therapy for the subject than is provided by conventional inexsufflation systems in which inspiratory flow may not be monitored and/or controlled. In one embodiment, the system comprises one or more of a pressure generator, a subject interface, one or more sensors, a processor, a user interface, electronic storage, and/or other components.
