A system includes a guidance device that provides feedback to a user to compress a patient's chest at a rate of between about 90 and 110 compressions per minute and at a depth of between about 4.5 centimeters to about 6 centimeters. The system includes a pressure regulation system having a pressure-responsive valve that is configured to be coupled to a patient's airway. The pressure-responsive valve is configured to remain closed during successive chest compressions in order to permit removal at least about 200 ml from the lungs in order to lower intracranial pressure to improve survival with favorable neurological function. The pressure-responsive valve is configured to remain closed until the negative pressure within the patient's airway reaches about 7 cm H.sub.2O, at which time the pressure-responsive valve is configured to open to provide respiratory gases to flow to the lungs through the pressure-responsive valve.

Vibration based stimulation or pressure based stimulation are commonly employed in a wide range of devices for medical, therapeutic, and recreational activities. These are designed to be applied against a predetermined region of a user's body. However, there are many instances where it would beneficial to provide the user with a wearable device where these one or more predetermined regions of the user's body may be inserted through or disposed within the device providing vibratory and/or pressure based stimulation. Further, such devices may be augmented with other therapeutic means such as light therapy or ultrasonic therapy. Accordingly, a range of wearable devices exploiting hollow shaft motors, electromagnetic actuators, and fluidics are presented.

A wearable medical device, comprising: a garment configured to be worn about a torso of a patient; one or more sensors for detecting a characteristic of a cardiopulmonary resuscitation (CPR) therapy; an output device; and a processor configured for processing information from the one or more sensors and providing, to the output device, information about the CPR therapy, wherein at least one of the one or more sensors is movably attached to the garment, the at least one sensor configured to be positioned to the center of the patient's chest prior to initiation of the CPR therapy.

Methods, systems and devices for reducing anxiety, including increasing relaxation and/or calm. In some variations these methods may include reducing anxiety, increase relaxation and/or calm by non-invasive temperature regulation of the frontal cortex prior to and/or during sleep. The subject may have an anxiety disorder, or may not have a diagnosed anxiety disorder.

An external defibrillator system includes one or more compression sensors; one or more physiological sensors; and at least one processor. The at least one processor is configured to: receive and process chest compression signals and physiological signals from the sensors, determine values for chest compression depth and/or chest compression rate based on the received chest compression signals, determine a trend of at least one physiological parameter over a period comprising multiple chest compressions based on the received physiological signals, adjust a target chest compression depth and/or target chest compression rate based on the determined trend of the at least one physiological parameter, compare the determined values for chest compression depth and/or chest compression rate to the adjusted target compression depth and/or the adjusted target compression rate, and provide feedback about the quality of chest compressions performed on the patient.

A motion augmentation system configured to utilize a plurality of cables to augment the user's native strength to aid in the movement of an appendage of a user through a desired range of motion by applying forces between a first body part and an appendage of the user, such that a natural anatomy of the user is at least partially used as a structure to affect movement. The motion augmentation system including a plurality of cables operably coupling a body chassis to at least one sleeve assembly, each of the plurality of cables traversing through a corresponding one of a plurality of embedded lumens within the sleeve assembly and controlled by one or more corresponding cable actuators operably coupled to the body chassis, the corresponding cable actuators configured to selectively apply a force via the plurality of cables between the body chassis in the at least one sleeve assembly.

Medical devices, plug-ins, systems, and methods for CPR quality feedback are disclosed. The medical devices can calculate peripheral circulation relevant parameters based on measured signals containing at least partial hemodynamic characteristics. Amplitude and area characteristics included in the peripheral circulation relevant parameters can further be determined for providing feedback and control relating to CPR quality during the compression process. Also, compression interruption during CPR can be evaluated based on a pulse waveform generated from the measured signals.

A system for assisting a user in performing chest compressions includes: at least one input device for providing information representative of a plurality of physical features of a patient; at least one chest compression sensor; a feedback device for providing chest compression feedback for the user; and at least one processor. The at least one processor is configured to: receive and process the information representative of the plurality of physical features of the patient to determine a target chest compression criterion for the patient, receive and process the signals indicative of the chest compressions from the at least one chest compression sensor to calculate at least one chest compression parameter, determine whether the at least one chest compression parameter meets the target chest compression criterion, and cause the feedback device to provide an indication for the user of whether the chest compression parameter meets the target criterion.

A wearable haptic navigation system for obscured visibility environments, the wearable haptic navigation system including: a wearable haptic component, in one alternative a body covering suite; and a mapping data collector and processor in communication with the wearable haptic component; wherein the mapping data collector and processor collects data related to a path traversed by a user of the wearable haptic navigation system and generates at least one proprioception suggestion signal to the wearable haptic component providing the user with a suggested safe egress path and/or a suggested safe body position.

The system provides a real-time video and audio communication with a 911 call center to perform effective CPR on a patient experiencing OHCA with real-time monitoring and feedback. The system includes a Mobile App that communicates with a smart phone with camera, a wireless remote-CPR equipment stand and emergency CPR kit. The mobile app will automatically send a link to a caregiver's cell phone responsive to a 911 call placed by the caregiver, to establish a secured video call via which the 911 center can guide the caregiver in performance of CPR until an ambulance arrives.
