The present disclosure pertains to systems and methods for delivering sensory stimulation to a subject for facilitating sleep onset. The system comprises one or more sensors for generating output signals indicating one or more physiological parameters of a subject; a sensory stimulator for delivering sensory stimulation to the subject; and one or more physical processors configured to: determine an initial state of the subject based on the output signals from the sensor, the initial state corresponding to at least one physiological parameter of the subject; determine one or more stimulation parameters of sensory stimulation to be delivered to the subject by the sensory stimulator based on the initial state of the subject; and cause the sensory stimulator to deliver the sensory stimulation to the subject based on the determined one or more stimulation parameters.

A sleep induction device includes at least one sensor for detecting a physiological characteristic of the user, a stimulator configured to provide successive stimuli to the user to anticipate on the detected physiological characteristic, which successive stimuli define a guidance path, and which guidance path is to be followed by the user to induce a change during the sleep session of the user, a memory which is arranged to store values of detected physiological characteristics, and provided stimuli during the sleep session, and a processing unit including a control programme which is programmed to determine a current sleep state of the user, which current sleep state is based on at least one detected physiological characteristic measured by the at least one sensor and which control programme is programmed to generate an initial guidance path to induce a change from the determined current sleep state to another sleep state.

Systems methods are described for modifying sleep patterns based on biofeedback. The method may include identifying a target sleep pattern from a plurality of candidate sleep patterns, receiving biofeedback information from a user, identifying a stimulus pattern based on the target sleep pattern and the biofeedback information, and providing at least one stimulus to the user based on the stimulus pattern.

Methods and apparatus for assessing the condition of and treating patients for heart failure by the delivery of continuous positive airway pressure are disclosed. Treatment of obstruction due to reflex vocal cord closure often experienced by heart failure patients is distinguished from treatment of upper airway obstruction typically associated with Obstructive Sleep Disorder. Treatment may also be implemented by delivering synchronized cardiac pressure oscillations superimposed on a respiratory pressure level to provide assistance for the heart. Heart treatment pressure dose indicator may be calculated for prescribing and monitoring the delivery of treatment. The apparatus may also generate data to track heart failure condition that may be indicative of the degree of severity of heart failure based upon breathing patterns to assist in the diagnosis and management of heart failure patients.

A nasal delivery system comprising a nasal insertion tube and a fluid medium located in communication with the nasal insertion tube. The nasal insertion tube comprises a tubular wall forming an internal flow path from an inlet to an outlet. The outlet is configured to be arranged in a nostril of a person to thereby facilitate an upstream flow of air in a first flow path from an ambient space through the internal flow path to the respiratory tract of the person during inhaling and a downstream flow of air in a second flow path from the respiratory tract of the person outside the internal flow path to the ambient space during exhaling. The system further comprises a flow diverter structure configured for providing a first ratio between the flow resistance in the first flow path and the flow resistance in the second flow path during upstream flow and for providing a second ratio between the flow resistance in the first flow path and the flow resistance in the second flow path during downstream flow, where the second ratio is equal to or higher than the first ratio.

A device, system, and method for facilitating a sleep cycle in a subject, comprising selecting a waveform from a plurality of waveforms derived from brainwaves of at least one sleeping donor, wherein said waveform corresponds to at least one specific stage of sleep; and stimulating the subject with at least one stimulus, wherein said at least one stimulus is at least one of an auditory stimulus and a visual stimulus modulated with the selected waveform to entrain the brain of the subject with the selected waveform to facilitate sleep in the subject.
