In an aspect, a system for treating a patient in cardiac arrest is described and includes memory, one or more electronic ports for receiving signals from sensors for obtaining indications of an electrocardiogram (ECG) of the patient, one or more sensors for obtaining a transthoracic impedance of the patient, and a patient treatment module executable on one or more processing devices that is configured to generate, from the ECG, transform values that represent magnitudes of two or more frequency components of the ECG, and modify, based on at least one transform value, at least one shock delivery parameter.

A multi-sensory media experience delivery platform includes a vibroacoustic therapy bed that delivers a multi-sensory media experience locally stored, streaming, on-demand, or real-time signals. The vibroacoustic therapy bed drives a plurality of sensory output devices based on a set of sensory output channels to produce sounds, vibrations, light patterns, or other sensory outputs. The channels may be derived from dedicated signals created for a specific sensory output device or may be derived from an audio file or other general set of waveforms. The multi-sensory media experience may be customized to a user based on user profile data, metadata associated with the multi-sensory media experience, or biometric data. Furthermore, users can create customized multi-sensory media experiences from libraries of sounds or other media.

A system for improving cardiac output of a patient suffering from pulseless electrical activity or shock and yet displays myocardial wall motion including: a sensor to detect myocardial activity to determine the presence of residual left ventricular pump function having a contraction or ejection phase and a filling or relaxation phase, a device to prompt the application of or apply a compressive force repeatedly applied to the chest based on the sensed myocardial activity such that the compressive force is applied during at least some of the ejection phases and is ceased during at least some of the relaxation phases to permit residual cardiac filling, thereby enhancing cardiac output and organ perfusion.

Systems and methods for exerting forces on a body, including a support structure defining a space and a plurality of surface contacting units that are configured to exert force upon the body, such that the weight is distributed away from the primary weight bearing regions to non-weight bearing regions of the body, or vice versa, without exerting significant shear or frictional forces on surfaces of the body. The systems and methods may be used to exert forces to cause fluid shift in different compartments of the body. Applications include treatment of various disease conditions including pressure ulcers, heart failure, high blood pressure, preeclampsia, osteoporosis, injuries of spine and to slow microgravity-induced bone and muscle loss. The systems and methods may be used to simulate gravity, weightlessness or buoyancy, in rehabilitation medicine. The system may include a chair, bed, a wearable suit or an exoskeleton.

Methods and systems are disclosed for capturing sensor data collected by a personal massaging device with associated sensors, analyzing the data, determining biofeedback data based on the sensor data, and according to some embodiments generating a sexual response profile based on the biofeedback data and a model of human sexual response. Data may be collected and analyzed for a number of uses, including but not limited to: (1) studying human sexual response, (2) adjusting outputs of the personal massaging device based on preset conditions, (3) treating sexual dysfunction conditions, and (4) improving sexual experiences.

Patient therapy and patient condition sensing devices and methods can be operated as a function of estimated internal hydrostatic pressure of a body part, for example at a position where a pressure or compression therapy is applied. Information relating to a patient's position, posture, ambulation and/or a physiological condition such as blood pressure can be used to control pressure or compression therapy.

Systems and methods disclosed herein relate to augmenting a treatment modality. A method of providing stimulation therapy to a user may include generating transcutaneous vibratory output comprising one or more variable parameters, subjecting the user, in conjunction with the transcutaneous vibratory output, to a treatment modality, wherein the one or more variable parameters of the transcutaneous vibratory output comprise at least one of a perceived pitch, a perceived beat, a perceived intensity, an envelope, or a base tone, and at least one of selecting or modifying the one or more variable parameters of the transcutaneous vibratory output to augment the treatment modality.

A vibrotactile stimulation device intended to be applied against a body medium (MC) to be stimulated, produced in the form of a functional unit, comprising a vibrating effector suitable for applying, to said medium, pulses of mechanical vibrational energy, and a controller for controlling the effector according to stimulation rules. The functional unit further houses a first electrode suitable for cooperating with at least one second electrode separated from the first electrode in order to supply signals representative of a cardiac activity and a muscular activity on the medium to be stimulated, said controller being sensitive to cardiac activity and muscular activity signals in order to influence the stimulation. The stimulation device may be used for body stimulation in combating sleep apnea, with improved detection.

Systems and methods of assisting a subject to reach a target state include obtaining input of the target state of the subject; and generating a transcutaneous vibratory output to be applied to a portion of a body of the subject to assist the subject in achieving the target state, the transcutaneous vibratory output having variable parameters comprising a perceived pitch, a perceived beat, and a perceived intensity wherein the step of generating the transcutaneous vibratory output further comprises the step of modifying the variable parameters to correspond to the target state.

Examples described herein include defibrillators or other medical equipment that may employ hidden Markov models to classify cardiac rhythms in ECG signals. Hidden Markov models may additionally or instead be used to determine presence of a chest compression from the thoracic impedance signal. Classification of cardiac rhythms may be used to determine when to deliver a shock to a patient. Other applications are also described.
