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.

The left pressure source can be configured to generate a left cavity pressure independently of the right pressure source and the right pressure source can be configured to generate a right cavity pressure independently of the left pressure source.

An apparatus includes a first wire and a second wire which are coupled to a right upper ankle belt and a right lower ankle belt, a third wire and a fourth wire which are coupled to a left upper ankle belt and a left lower ankle belt, an obtainer obtaining information about a road surface where a user walks, and a controller controlling tensions of the first wire and the second wire at the same time and controlling tensions of the third wire and the fourth wire at the same time using a first stiffness target value corresponding to the first wire, a second stiffness target value corresponding to the second wire, a third stiffness target value corresponding to the third wire, and a fourth stiffness target value corresponding to the fourth wire that are determined based on the information about the road surface.

A handheld acoustic shock wave or pressure pulse applicator device has a body structure and an applicator head. The body structure has a proximal end and a distal end with a longitudinal axis extending between the ends. The applicator head is at the distal end. the head emits pressure pulses or shock waves at an inclined angle relative to the longitudinal axis of the body structure. The applicator head has a balloon or lens or membrane through which the emitted pressure pulses or shock waves pass. The lens or membrane is configured to be coupled directly or indirectly to an exposed soft tissue surface of a palate inside a patient's mouth to direct emitted pressure pulses or shock waves to the brain. The applicator device can be configured with the inclined obtuse angle fixed between 150 degrees and 90 degrees or can be adjustable between 180 degrees and 90 degrees.
