An environment control system utilizes oxygen and humidity control devices that are coupled with an enclosure to independently control the oxygen concentration and the humidity level within the enclosure. An oxygen depletion device may be an oxygen depletion electrolyzer cell that reacts with oxygen within the cell and produces water through electrochemical reactions. A desiccating device may be g, a dehumidification electrolyzer cell, a desiccator, a membrane desiccator or a condenser. A controller may control the amount of voltage and/or current provided to the oxygen depletion electrolyzer cell and therefore the rate of oxygen reduction and may control the amount of voltage and/or current provided to the dehumidification electrolyzer cell and therefore the rate of humidity reduction. The oxygen level may be determined by the measurement of voltage and a limiting current of the oxygen depletion electrolyzer cell. The enclosure may be a food or artifact enclosure.

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.

Introduced are a bed device system and methods for: gathering human biological signals, such as heart rate, breathing rate, or temperature; analyzing the gathered human biological signals; and controlling the bed device system, e.g., a temperature of the bed device, based on the analysis.

A patient interface includes: a plenum chamber; a seal-forming structure; a positioning and stabilising structure; a plenum chamber insert configured to be positioned and retained within the plenum chamber; and a vent structure; wherein the plenum chamber insert has a plenum chamber insert port; wherein the plenum chamber insert has an exterior surface configured to be positioned adjacent to an interior surface of the plenum chamber; wherein when the plenum chamber insert is positioned and retained within the plenum chamber, a radial channel is formed by the interior surface of the plenum chamber and the exterior surface of the plenum chamber insert such that gas is able to pass between a patient-proximal side of the plenum chamber insert and a patient-distal side of the plenum chamber insert via the radial channel during use.

Methods and apparatus, such as a controller of a respiratory therapy device, generate a signal representing an estimate of flow rate of gas flow from the device. The respiratory therapy device may include a motor-operated blower. The method may include receiving in the controller, signals generated by a set of sensors, including measures of pressure and frequency (e.g., speed) of the motor. The controller may be configured to compute an entrained air density function and generate the estimate signal based on a function of the measures of pressure and frequency, and the entrained air density function. The entrained air density function may apply signals from additional sensors, such as atmospheric pressure, gas temperature, and ambient relative humidity, to compute atmospheric density. Control operations of the therapy device may then be based on the estimated signal, which may be applied to assess accuracy of a signal from a flow sensor.

A system for providing continuous positive air pressure therapy is provided. The system includes a flow generator, a sensor, and a computing device. The computing device is configured to control operation of the flow generator based on sensor data. The computing device is further configured to display, on a display device, one or more questions relating to demographic and/or subjective feedback; responsive to displaying the one or more questions, receive one or more inputs indicating answers to the one or more questions; transmit the answers to a remote processing system; receive, from the remote processing system, settings determined based on the transmitted answers; and adjust control settings of the system based on the received settings.

A nebulizer system capable of identifying when activation has occurred and aerosol is being produced. The nebulizer system monitors the inhalation and exhalation flow generated by the patient and communicates proper breathing technique for optimal drug delivery. The nebulizer system may monitor air supply to the nebulizer to ensure it is within the working range and is producing, or is capable of producing, acceptable particle size and drug output rate. When a patient, caregiver or other user deposits or inserts medication into the nebulizer, the nebulizer system is able to identify the medication and determine the appropriate delivery methods required to properly administer the medication as well as output this information into a treatment log to ensure the patient is taking the proper medications. The system is able to measure the concentration of the medication and volume of the medication placed within the medication receptacle, e.g., bowl.

Introduced are methods and systems for: gathering human biological signals, such as heart rate, respiration rate, or temperature; analyzing the gathered human biological signals; and controlling a vibrating pillow strip based on the analysis.
