An exoskeleton device is provided herein that includes a control unit having at least one actuator. A transmission assembly operably couples the control unit to a hinged assembly. A sensor is coupled to the hinged assembly and is configured to acquire data in reference to use of the hinged assembly. The exoskeleton device also includes a feedback modality. A controller is in communication with the sensor and feedback modality. The controller is configured to activate the feedback modality based on a measured performance metric that is determined from the acquired data.

A method of using an ankle exoskeleton device is provided herein. The method includes collecting one or more biomechanical data points from an individual. The method also includes developing individualized musculoskeletal simulations based on the one or more biomechanical data points. In addition, the method includes creating predictive simulations by modeling effects of an ankle exoskeleton device on the individualized musculoskeletal simulations. The method also includes utilizing established device-user relationships with real-time measurements to adjust device control. Lastly, the method includes optimizing design and control parameters of the exoskeleton device based on the predictive simulations and user responses.

A method of increasing blood flow to the head includes causing an individual's blood to circulate while the individual's heart and head are at a first elevation position, elevating the individual's heart and head to a second elevation position that is above the first elevation position, and causing the individual's blood to circulate while the individual's heart and head are at the second elevation position.

The invention relates to a respiratory assistance apparatus for delivering a respiratory gas, such as air, to a patient during cardiopulmonary resuscitation (CPR), having a source (1) of respiratory gas, means (4) for measuring the CO.sub.2 content, and signal-processing and control means (5). The signal-processing and control means (5) are configured to process the CO.sub.2 content measurement signals corresponding to measurements performed by the CO.sub.2 content measurement means (4) during a given period of time (dt), and to calculate at least one mean CO.sub.2 content value (Vmean) from the maximum CO.sub.2 content values (Vmax) obtained over the time window (Ft), and to transmit said at least one mean CO.sub.2 content value (Vmean) to the graphical user interface (7) which displays it.

A system and method for mechanical CPR can include a device for providing compressive force to various locations on a patient, and biological monitoring systems to measure the effectiveness of the various locations of compressive force in pumping blood through the patient. The system can also include providing decompressive force to increase the efficacy of blood flow.

The disclosed CPR devices, systems, and methods adjust a compression depth of a compression mechanism to account for chest collapse of the patient receiving CPR. Compression depth can be adjusted up to a maximum depth in some examples. The compression depth can also be adjusted linearly or non-linearly as the zero point or starting position of the patient's chest changes due to chest collapse. Other factors can also be used to adjust the compression depth such as patient parameters that can be observed by a rescuer or sensed by sensors wirelessly connected to or integrated into the system. CPR devices that include active decompression can also use the disclosed techniques for adjusting the chest compression depth as the patient's chest collapses.

In embodiments, a CPR chest compression system includes a retention structure that can retain the patient's body, and a compression mechanism that can perform automatically CPR compressions and releases to the patient's chest. The compression mechanism can pause the performing of the CPR compressions for a short time, so that an attendant can check the patient. The CPR system can include a user interface that can output a human-perceptible check patient prompt, to alert an attendant to check the patient during the pause. The compression mechanism can during a CPR session retreat a distance away from the patient's chest whereby the patient's chest can expand without active decompression of the patient's chest beyond the chest's natural resting position.
