Among other things, in one aspect, we describe a system for assisting with cardiopulmonary resuscitation (CPR). The system includes at least one sensor; and one or more processors configured for calculating a chest compliance relationship based on data received from the at least one sensor, and determining a neutral position of chest compression based at least in part on a feature of the chest compliance relationship. The system can take the form of an active compression-decompression device.

A system for monitoring and/or reviewing transitions between types of medical treatment events provided for a patient during a rescue effort includes a medical device and a computing device. The medical device includes a chest compression sensor configured to receive time-correlated signals representative of chest compressions. The medical device is configured to generate a case file for the rescue effort comprising times of occurrence for a plurality of medical events. The computing device is configured to: receive the case file for the rescue effort, select and determine the time of occurrence for a first event of the plurality of medical events from the case file, select and determine the time of occurrence for a second event of the plurality of medical events, and determine a transition time between the time of occurrence of the first event and the time of occurrence of the second event.

A garment with prepositioned, definite sensory stimulating devices attached. The sensory stimulating devices include, but are not limited to, electrical stimulation, audio and physical stimulation such as localized force generation, compression, constriction, vibration, and surround sound. Predetermined and defined actuators allow the wearer to receive tissue, nerve and/or muscle stimulation and/or contraction so that the stimulation is precise as determined by its ability to conform to the scientific methodology of repeatability, reproducibility and reliability; this being due to consistency of actuator positioning in one or multiple locals on the human body. A personal surround sound can also be integrated to the garment to ensure the wearer is always in the optimal position relative to the speakers. These actuators can be force generators within the garment for the wearer to feel impact or apparatus or electrodes included in the garment to locally constrict and increase pressure to the wearer.

Systems and methods are provided for controlling infrared radiation (IR) sources of a sauna including tuning IR wavelength-ranges and radiated power-levels of IR sources, and directing IR to locations on a user's body. In one illustrative embodiment, a sauna may be provided having adjustable IR emitters to emit IR at any wavelength resulting in a desirable radiation treatment for the sauna user. In another illustrative embodiment, a method is provided for tuning IR emitters in a sauna.

A system for assisting with a cardiopulmonary resuscitation (CPR) treatment being administered to a patient. In one aspect, a system for assisting with a cardiopulmonary resuscitation (CPR) treatment being administered to a patient includes a sensor for determining a parameter of the patient (e.g., indicative of a blood flow or pressure waveform), and one or more processors configured for receiving input from the sensor, determining, based on the input from the sensor, whether a rate of chest compressions administered in the CPR treatment should be changed, and providing an indication to a user that the rate of chest compressions should be changed.

A system for assisting with a cardiopulmonary resuscitation (CPR) treatment being administered to a patient. In one aspect, the system includes electrodes to provide an ECG signal of the patient, one or more sensors configured to measure an intrinsic myocardial wall movement of the patient, and one or more processors. The one or more processors are configured to perform operations including: during the CPR treatment being administered to the patient, receiving an input from the sensor(s), processing the input from the sensor(s) and the ECG signal, determining, based on processing, whether the intrinsic myocardial wall movement is indicative of a perfusion movement of the patient's heart, and providing an indication to a user of the system based on the determination.

An ambulatory medical device is provided. The ambulatory medical device includes at least one sensor configured to acquire physiological data of a patient, at least one network interface and at least one processor coupled to the at least one sensor and the at least one network interface. The at least one processor is configured to detect, via the at least one network interface, a medical device, to establish a secure communication session with the medical device via the at least one network interface, to detect a data capacity of the secure communication session, to identify a category of patient data associated with the data capacity, and to transmit patient data of the category to the medical device via the secure communication session.

It is disclosed an apparatus (100) for tactile stimulation of C-Tactile afferents comprising a casing (10) configured to be positioned onto a user's skin and at least one tactile stimulation element (21) carried by the casing (10) and operated by a motor (30) at a controlled velocity for generating at least one tactile stimulation. The apparatus (100) further comprises an electronic control unit (40) and at least one pressure sensor (50) in electrical communication with the electronic control unit (40) to control the pressure force exerted by the tactile stimulation element (21) onto the user's skin by adjusting the position of the tactile stimulation element (21) with respect to the user's skin, based on a feedback signal transmitted by said at least one pressure sensor (50). A method of generating at least one tactile stimulation of C-Tactile afferents carried out by using the aforesaid apparatus (100) is also disclosed.

An apparatus for assisting a rescuer in performing chest compressions during CPR on a victim, the apparatus comprising a pad or other structure configured to be applied to the chest near or at the location at which the rescuer applies force to produce the chest compressions, at least one sensor connected to the pad, the sensor being configured to sense movement of the chest or force applied to the chest, processing circuitry for processing the output of the sensor to determine whether the rescuer is substantially releasing the chest following chest compressions, and at least one prompting element connected to the processing circuitry for providing the rescuer with information as to whether the chest is being substantially released following chest compressions.

An external defibrillator system for assisting manual delivery of chest compressions and ventilations to a patient by a rescuer as cardiopulmonary resuscitation (CPR) includes a speaker, and a processor, memory, and associated circuitry coupled to the speaker. The processor is configured to initiate prompting for the chest compressions and the ventilations manually delivered to the patient by the rescuer as CPR, control the speaker to generate first auditory cues for the chest compressions, and control the speaker to generate second auditory cues for the ventilations with a different sound than the first auditory cues for the chest compressions. The first auditory cues and the second auditory cues assist the rescuer in timing the delivery of the chest compressions and the ventilations.
