Methods and apparatus provide automated controls for a respiratory pressure therapy device, such as a servo-ventilator. For example, a controller of a respiratory pressure therapy device may control application of pressure support ventilation therapy to an airway of a patient. The controller may control the respiratory pressure therapy device to auto-titrate an expiratory positive airway pressure (EPAP) of a pressure support ventilation therapy so as to maintain airway patency of the patient. The EPAP may be bounded below by a floor pressure limit. The controller may control the respiratory pressure therapy device to repeatedly adjust the floor pressure limit depending on events of interest during the auto-titration of the EPAP. Such methodologies may improve treatment for patients such as those suffering from sleep disordered breathing-comorbid hyperarousal disorders.

Sleep management apparatus including a wearable device having one or more physiological sensors operably engaged with a body of a user. One or more processors can be communicatively coupled with the wearable device having a memory storing instructions when executed operable to: detect one or more indicators of a bedtime; measure one or more physiological indicators predictive of a ready for sleep condition of the user; suggest, when one or more of the one or more physiological indicators exceed a predetermined threshold, a sleep preparation exercise; and track an effectiveness of the sleep preparation exercise.

Quantitative colorimetric carbon dioxide detection and measurement systems are disclosed. The systems can include a gas conduit, a colorimetric indicator adapted to exhibit a color change in response to exposure to carbon dioxide gas, a temperature controller operatively coupled to the colorimetric indicator and configured to control the temperature of the colorimetric indicator, an electro-optical sensor assembly including a light source or sources adapted to transmit light to the colorimetric indicator, and a photodiode or photodiodes configured to detect light reflected from the colorimetric indicator and to generate a measurement signal, and a processor in communication with the electro-optical sensor assembly. The processor can be configured to receive the measurement signal generated by the electro-optical sensor assembly and to compute a concentration of carbon dioxide based on the measurement signal. Methods for using the systems are also disclosed including providing a breathing therapy to a patient or user.

A breathing motion simulator for simulating an expanding and retracting movement of live breathing, includes a pump and an inflatable bladder for generating a repetitive motion resembling a breathing motion. The simulator includes a cover plate positioned across the bladder and a cover guidance for linearly guiding the cover plate with respect to a base body. The cover guidance includes at least a first living hinge unit and a second living hinge unit oriented in a non-parallel direction with respect to each other for constraining a rotational movement of the cover plate, where each living hinge unit includes at least three stacked living hinges defining a set of three pivot axes in parallel for allowing a translational movement of the cover plate, such that the cover guidance enables a linear movement of the cover plate.

Adverse effects of pain in a premature infant, especially a very or extremely premature infant may be ameliorated by exposing the infant to stimuli comprising one or more of vertical oscillating motion simulating breathing, skin contact with an interface that mimics human skin and exposure to sounds and/or vibrations that simulate heartbeats. A device including a movable platform provides such stimuli within a neonatal intensive care incubator. The device provides simulated maternal breathing through vertical movement at a rate and speed similar to that experienced by an infant lying upon its mother's chest. It further provides simulated maternal skin interface feel as well as heartbeat sound. These simulated sensory parameters appear to have an innate calming effect upon a preterm infant that reduces the duration and severity of the infant's response to a pain event. The same stimulations may reduce occurrence of below-baseline fluctuations of brain blood oxygen content.

Systems and methods are provided that provide respiration entrainment cues to a user to encourage relaxation or a sleep state. The entrainment cues may be audible, visible, or tactile (or any combination). The entrainment cues include a rhythmic component associated with a target respiration rate and may include sub-components associated with a target breath architecture, such as an inhale-exhale cycle. The systems and methods detect the user's respiration to determine whether the user's respiration matches the entrainment cues or whether the user has fallen asleep.

A processing system includes methods to promote sleep. The system may include a monitor such as a non-contact motion sensor from which sleep information may be determined. User sleep information, such as sleep stages, hypnograms, sleep scores, mind recharge scores and body scores, may be recorded, evaluated and/or displayed for a user. The system may further monitor ambient and/or environmental conditions corresponding to sleep sessions. Sleep advice may be generated based on the sleep information, user queries and/or environmental conditions from one or more sleep sessions. Communicated sleep advice may include content to promote good sleep habits and/or detect risky sleep conditions. In some versions of the system, any one or more of a bedside unit 3000 sensor module, a smart processing device, such as a smart phone or smart device 3002, and network servers may be implemented to perform the methodologies of the system.

A respiratory ventilation device—configured to send an airflow, generated by a fan, into a duct that extends between the device and a breathing mask configured to be worn by a user—comprises an air inlet intended to admit air into the device; a fan; and an air outlet configured to be connected to the duct, such that, when the fan is in operation, the air flows from the air inlet successively toward the fan and then toward the air outlet. The device also comprises a flow rate sensor configured to measure a flow rate of air circulating through the device, and/or a pressure sensor configured to measure a pressure between the fan and the air outlet. A control unit is connected to the flow rate sensor and/or to the pressure sensor. The device also includes at least one source of light.

An intelligent baby caring method and arrangement helps to recognize and maintain emotional interaction between mother and her baby and to improve the baby's life rhythm and calm and soothe him/her automatically when needed and help him/her to fall asleep and to wake up at the most convenient time and way. The aim is to help the mother with her baby to find optimal life and care rhythm. The invention is focused on a platform (101) with many sensors, sensor sheet (120), a transducer to produce acoustic and mechanical vibrations (14) and an airflow blower (132). Sensors are also fixed to the mother (10) and in the care room (198). A sleep/activity graph of the baby and sleep/emotion graph of the mother are measured and tracked with multimodal sensors and an artificial intelligence unit (200) processes audio, motion and airflow actions given to the baby from the platform to help the baby to move from an improper to optimal sleep/activity level.

A monitoring system for use with a human simulator for simulating interaction between a human baby and a bonded human and method of operating thereof are disclosed. The simulator comprises a housing having an outer layer configured to contact the baby, the housing having a surface contoured to simulate a torso of the bonded human; a respiration simulation system configured to simulate a respiration motion of the bonded human; and a heartbeat simulation system configured to simulate a heartbeat of the bonded human. The monitoring system comprises a smart device having a first communication interface; one or more sensors for detecting one or more biological parameters of the bonded human; at least one processor programmed with machine readable instructions to activate the sensor(s) and to transmit a signal corresponding to the detected biological parameters from the first communication interface to a second communication interface connected to the simulator.
