A bed includes components to control pressure of a sleep surface, for example based on sleep position and sleep stages of a user. In some embodiments target pressures for the sleep surface are iteratively adjusted over multiple sleep sessions so to achieve improvements in sleep states and/or sleep quality for the user.

Provided is a biofeedback device using an electrocardiogram, and the biofeedback device using an electrocardiogram may include: a signal acquisition unit acquiring an electrocardiogram signal of a user from an electrocardiograph; an analysis unit analyzing the acquired electrocardiogram signal and providing a state diagnosis result of the user as an analysis result; and a control unit controlling at least one stimulation unit among a plurality of stimulation units for state control of the user based on the state diagnosis result, and a stimulation corresponding to the at least one stimulation unit may be provided to the user by the control of the control unit.

A hand stimulation device that includes a housing defining an interior plenum and having a top portion and a bottom portion; a pair of drive electrodes structured and arranged in a first region of the top portion; a pair of sense electrodes structured and arranged in a second region of the top portion; a processing device disposed within the interior plenum and in communication with each of the pair of drive electrodes and the pair of sense electrodes; at least one sensing device adapted to measure and collect biometric data about the user; and at least one motor that is adapted to generate at least one of tactile feedback and a haptic pattern to a user.

A wearable device has a flexible and extendable body configured to encircle a portion of a body of a user, an electronics module with a concave space between two ends, each end attachable to the flexible and extendable body with a flexible retention mount to allow rotation of the flexible and extendable body relative to the electronics module and to transfer tension force from the flexible and extendable body to the electronics module, and a bio-signal sensor disposed on the flexible and extendable body to contact at least part of the body of the user and to receive bio-signals from the user.

A liquid ventilation system includes a reservoir holding a perfluorochemical (“PFC”) fluid, and a suction pump connected to the reservoir to reduce pressure within the reservoir. A sensor is configured to measure an intra-lung pressure. An appliance is configured to be disposed within a patient. The appliance carries an injector to supply the PFC fluid through the appliance. An extraction valve is disposed on an extraction line between the appliance and the reservoir. The extraction valve is arrangeable between a first position enabling fluid communication from the appliance to the reservoir and a second position disabling fluid communication from the appliance to the reservoir.

The present disclosure is directed to a bedding panel system comprising a bottom or fitted sheet with embedded channels throughout such that at least one or more modular top panels and cushions can be attached to create physical sleep chamber spaces and thus independent “sleep zones” for multiple occupants on a single mattress. A bedding panel system can have dimensions to fit any size mattress. Fitted sheet, modular panels and cushions can include several layered components, each with comfort or utility features for each sleep chamber space. Top and bottom layers of fitted sheet and modular panels may be comprised of various fabrics and materials desirable for sleep comfort. Middle layers of fitted sheet and modular panels can include items such as foam or gel padding, moisture resistant barriers, biometric sensors for measuring physical health and sleep quality, and hardware for heating and cooling. Customized foot panels with specialized materials and electronic components can also be attached to fitted sheet for elevated comfort in the foot box. Bedding panel system components can be embedded with channels, arranged in crisscross and diagonal patterns, containing reinforced holes spaced symmetrically throughout to accommodate different configurations for modular panel and cushion installations. Anchor systems can include a variety of material and hardware combinations to enable ease of component connections, sleep comfort, and convenience of occupant access to sleep zones. Similar to modular panel configurations, anchors allow cushions, pillows, pillow cases and similar headrests designed for the head box section to remain connected to fitted sheet to ensure sleep materials remain intact and in place for the duration of the occupants sleep session.

Systems and techniques for monitoring, predicting and/or alerting for short-term oxygen support needs of patients are presented. A system can include a data collection component that receives multimodal patient data for a patient having a respiratory condition in association with monitoring and treating the respiratory condition in real-time, the multimodal patient data comprising at least physiological data regarding physiological parameters tracked for the patient over a period of time, and current oxygen support data regarding a current oxygen support mechanism of the patient. The system can further include an oxygen support forecasting component that processes the multimodal patient data using an oxygen support forecasting model to generate an output forecast that indicates whether a change to the current oxygen support mechanism is recommended for the patient within a defined upcoming timeframe

Disclosed are an automatic medication delivery system includes a stress detection and response algorithm or application that may operate in cooperation with a medication delivery algorithm or application. Execution of the instructions of the stress detection and response application causes a processor to obtain a respective measurement value related to a physiological condition of a user from one or more sensors. The obtained respective measurement values are evaluated against a respective threshold measurement value. The processor determines, based on the evaluation of the obtained respective measurement values, a degree of stress the user is experiencing. In response to the determination of the degree of stress the user is experiencing, the processor may modify an imminent dosage of a liquid drug to be delivered, a time of delivery of the imminent dosage, or both. A dosage of the liquid drug may be expelled based on the modifying.

Methods, systems and apparatus for inducing and verifying the level of neural entrainment at any target frequency, through a combination of biofeedback mechanisms, data analysis, and modulation of synergistic combinations of adaptable stimuli.
