Improved systems and methods for performing external counterpulsation (ECP) treatment are described. The system can be more compact and portable than conventional devices and, in some cases, can be incorporated into a pair of pants or a jumpsuit, such that the user can remain ambulatory during treatment. In various instances, the ECP techniques can include applying complex pulse sequences and treating conditions including cognitive disorders, diabetes, and renal disease, among others. The various techniques can also be used in emergency cardiac situations. The techniques can also be used to provide users with the benefits of exercise, without needing to experience the strain and difficulty associated with conventional cardiovascular exercise routines.

A massage chair includes a back massage system and a thigh massage system with a roller mechanism configured to move a roller in a three dimensional orbital motion. The roller mechanism is driven by a single motor that can change the direction in operation. Also included is a roller motion drive element within the roller mechanism. A shaft is configured to pass through the roller motion drive element in an offset non-perpendicular angle relative to the end face thereby forming an angle between the shaft and the end face that is less than 85 degrees. The offset causes the orbital motion of the roller when rotated. The electronics of the massage chair facilitate facial recognition and a medical assessment device to detect bodily characteristics. The backrest of the massage chair can elongate to stretch the user. A plurality of airbags are also available for the twisting of the user.

This disclosure describes methods and systems for preventing, moderating, and/or treating brain injury. The methods herein may include obtaining a test result reflecting a condition of a brain in the subject, determining a stimulation parameter based on the test result, and stimulating a nerve based on the stimulation parameter, wherein stimulation of the nerve assists or causes contraction of a respiratory muscle in the subject. The systems herein may include a processor configured to: receive a test result reflecting a condition of a brain in a subject, and determine a stimulation parameter based on the test result; and a stimulator configured to stimulate a nerve based on the stimulation parameter, wherein stimulation of the nerve assists or causes contraction of a respiratory muscle in the subject.

A concentration measurement apparatus measures a temporal relative change amount (cHb, O.sub.2Hb) of either or both of total hemoglobin concentration and oxygenated hemoglobin concentration in the head that vary due to repetition of chest compression, and includes a light incidence section making measurement light incident on the head, a light detection section detecting the measurement light propagated through the interior of the head and generating a detection signal in accordance with the intensity of the measurement light, and a CPU determining, based on the detection signal, the relative change amount (cHb, O.sub.2Hb) and performing a filtering process of removing frequency components less than a predetermined frequency from frequency components contained in the relative change amount (cHb, O.sub.2Hb).

Embodiments of the present disclosure relate generally to the use of spectral sensors during a cardiac arrest event. More specifically, the present disclosure relates to the use of spectral sensors for measuring changes in pH and muscle oxygen saturation to estimate subject down time and evaluating the effectiveness of the clinical treatment administered during a cardiac arrest event. Given the narrow window of time in which emergency treatment must be administered, as well as the lack of information concerning the subject's condition, there is a need for a fast and accurate method of estimating the onset of the cardiac arrest emergency and evaluating the effectiveness of the emergency treatment being administered.

Methods of treating subjects may include assisting breathing of the subject via an external respiratory support device. The methods of treating subjects may further include delivering an electrical signal to a first nerve of the subject, wherein delivering of the first signal blocks a pain signal from a pulmonary stretch pain receptor. The methods may further include placing one or more electrodes proximate a first nerve, wherein the first electrodes are supported on an intravenous catheter.

A cardiopulmonary resuscitation (CPR) device for performing automatic defibrillation and chest compressions on a patient and method for using same. The CPR device having a balloon configured to inflate/deflate, a belt configured to securely strap around a chest of a patient, a pair of electrode pads configured to deliver shock energy from a shock source, and, optionally, a pulse oximeter sensor. The CPR device is in electrical communication with a CPR defibrillator/ECG computer system that is configured to control the CPR device.

A device for delivering chest compressions for performing cardiopulmonary resuscitation includes a compression assembly and chest contact pad that can be positioned over the thorax of a patient experiencing a cardiac arrest. The compression assembly is supported by a frame and one or more positioning mechanisms for moving the compression assembly relative to the patient's left ventricle. A controller causes the compression assembly to deliver a plurality of chest compressions to the patient. A blood flow monitor, such as a Doppler ultrasound monitor, is coupled with the patient's femoral or carotid artery to monitor the flow of arterial blood when chest compressions are delivered and to communicate blood flow parameter information to the controller. The controller causes the positioning mechanism to move the location where the compressions are delivered to optimize the blood flow parameters. The controller monitors the blood flow parameters to determine the occurrence of a return to spontaneous circulation (ROSC). When ROSC is detected, the controller causes the compression assembly to cease chest compressions.

Embodiments disclosed herein are directed to personal therapy and exercise systems as well as to methods related thereto. For example, a personal therapy system can be a modular system that can include multiple therapy gear modules.
