The operational parameters of a respiratory apparatus can be controlled through the use of a user interface located on a separate or separable mobile computing device. Sensors or features located on the mobile computing apparatus can be used to adjust the operation parameters or therapy of the respiratory apparatus or otherwise improve the compliance of a patient utilizing the respiratory apparatus.

An apparatus for providing a humidified flow of pressurized breathable gas includes a humidification chamber having a heatable base surface and a humidification tub configured to contain a supply of water. The humidification tub includes a thermally conductive base and is removably positionable at least partially within the humidification chamber and onto the heatable base surface in order to allow for heating of the water in the humidification tub. The humidification chamber is configured to receive the flow of pressurized breathable gas and output the flow of pressurized breathable gas with increased humidity. The flow of pressurized breathable gas is pre-heated before entering the humidification tub by being configured to, after entering the humidification chamber and before entering the humidification tub, flow along at least a portion of the perimeter of the humidification tub.

A breathing assistance apparatus is configured with features that improve serviceability of the apparatus. The apparatus can include animations to provide instruction regarding correcting easily-identified fault conditions and to provide instruction regarding routine maintenance routines. The apparatus also can be configured with top level control menus that are obscured in a manner to limit manipulation of the top level control elements by unauthorized users.

The present disclosure describes a pressure support therapy device valve that enables a subject to safely supplement therapy pressure support with low flow oxygen while using a heated (or non-heated) tube. The valve conducts a pressurized flow of breathable gas and the low flow oxygen to the heated tube. The valve includes electrical components configured to pass power from the pressure support therapy device to the heated tube, and a plunger biased to close a flow path from the pressure support therapy device when a pressurized flow of breathable gas is not provided (or is below a predetermined pressure threshold). Closing the flow path stops oxygen gas from flowing back through the valve toward the pressurized gas source.

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.

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.

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 system comprises an intracavity device with an insertable portion having on its outer surface a sensor module which comprises at least a sensor of temperature, humidity or both; a second group of sensors comprising at least a volume sensor, a pressure sensor or both, wherein the fluid flows through the volume and/or pressure sensors; a fluid insufflation module; and a monitoring and control of the homeostasis module connected to the sensor module and to the second group of sensors and which comprises a processing unit.

The method comprises insufflating fluid into the cavity, to maintain a working volume and maintain the homeostasis of the cavity in a continuous manner, in particular the distensibility, temperature and humidity.

An apparatus for delivery of a flow of gases to a user, such as a respiratory therapy apparatus, is provided. The apparatus may have first and second inlets for receiving supplementary gases flows, a blower to generate the gases flow to the user, and a controller. A valve and a sensor may be provided in the second inlet. The controller may be configured to detect the disconnection of a gases source from the second inlet, and to respond by operating the valve and/or triggering an alarm. The controller may be configured to determine whether a gases flow is being provided at one or both of the inlets, and to accordingly control an operational mode of the apparatus.

The present disclosure is directed to a plurality of air quality devices configured to be held in a user's mouth and configured to increase at least one of humidity and temperature and constitution of air inhaled. There are passive and active systems that allow for improved physical and lung performance.
