Chest compression machine systems and methods adjust the administration of patient treatment based on received physiological parameter measurements, such as a CO.sub.2 measurement. Adjustment of the administered chest compressions can include adjusting one or more chest compression parameters, such as the depth of the administered compressions, the administration of active decompressions, adjusting the height of active decompression, adjusting the rate of compressions and/or active decompressions and/or other changes to one or more properties, or characteristics, of the administered chest compressions and/or active decompressions.

A device includes a first vibrational transducer and a second vibrational transducer. The first vibrational transducer has a first vibrating property. The second vibrotactile stimulator has a second vibrating property different than the first vibrating property. A collar may be configured to position the first vibrational transducer and the second vibrational transducer over a neck of a subject. A method for stimulating swallowing in a subject includes applying a first vibrotactile stimulation and applying a second vibrotactile stimulation to a throat area of the subject. The first vibrotactile stimulation has a first vibrating property and the second vibrotactile stimulation has a second vibrating property different than the first vibrating property. Example vibrating properties include vibrating frequency, vibrating frequency range, wave shape, continuousness, frequency phase, and direction of mechanical force.

A device, system, and method to control activation of oxygen saturation (SpO2) measurements in a cardio-pulmonary resuscitation (CPR) procedure. When compressions are present, only a PPG-based pulse detection algorithm is performed. When a spontaneous pulse has been detected and compressions are not detected during a predetermined time period, both a PPG-based pulse detection algorithm and an SpO2 measurement algorithm are performed. Depending on whether a chest compression is delivered manually or automatically, parameter selections for the compression detection algorithm, the PPG-based pulse detection algorithm, and the SpO2 measurement algorithm are adjusted accordingly.

A system and method for providing Thermal contrast therapy are presented. The system may comprise a fluid membrane barrier, a human interface device (HID), fluid tubing, a pump, and a reservoir. The system may be operable to apply any combination of heat, cold, and pressurized compression, light energy, acoustic energy, and vibratory energy to a therapy recipient for treating anal-prostate-perineal and vaginal areas, as well as podological and other extremities. The system may be operable to impart a desired therapy temperature to the human interface device and to expand a membrane containing a therapy fluid. The expanded membrane may conform to the contours of a therapy site. Operation of the human interface device may be controlled using a remote-control device. The therapy recipient may be able to control the temperature of the fluid or gel, as well as reception of light energy, acoustic energy and vibratory pulsing energy to assist in treatment of one or more conditions.

A walker with an automated power drive system is disclosed. The walker comprises a rigid frame comprising a left grip and a right grip; a plurality of wheels affixed to the rigid frame; a plurality of drive motors integrally mounted in the plurality of wheels; and a drive motor controller configured to power the plurality of drive motors. The drive motor controller is configured to: determine the orientation of the walker; generate a first motor current component to compensate for orientation of the walker and the resulting torque on the drive motor; determine the speed of the walker, generate a second motor current to component for internal friction based on the speed of the walker; determine a user force applied to the left grip and right grip; generate a third motor current component for the drive motors based on the user force applied to the left grip and right grip; and power the drive motors based on a sum of the first motor current component, second motor current component, and third motor current component. The drive motor controller is configured to determine the user force applied to the left grip and right grip based on a measured current from the drive motors. Specifically, the drive motor controller is configured to determine the user force applied to the left grip and right grip based on a difference between a target current provided to the drive motors and the actual current utilized by the drive motors.

A wearable safety system for either diving, harsh or anoxic environments, or for individuals at high risk for respiratory and/or cardiac failure is disclosed. The wearable safety system includes biometric monitoring and provides cardiac and/or respiratory support in the event that the wearer experiences cardiac and/or respiratory failure. There are different configurations of the wearable safety system designed to work with different use cases, and to provide different levels of protection. In the case of diving, the wearable safety system additionally utilizes data collected by the dive computer to advise a rescue diver as to the best course of action in managing an unconscious diver's ascent and can also inflate the diver's buoyancy control device (BCD) or onboard personal flotation device.

A distension/compression device for assisting breathing in a subject is disclosed. In one embodiment, a first tube includes a flexible and elastic material that forms a first tube lumen extending from a proximal end to a distal end of the first tube. Longitudinal expansion of the first tube is restricted less than radial expansion of the first tube. A connection element including a first air supply port is in fluid communication with an open proximal end of the first tube lumen and attached to a proximal end of the first tube. A method for assisting breathing of a patient and a method for assisting the clearing of secretions is also included.

A method for providing a therapeutic benefit includes receiving sensor data from one or more physiological sensors associated with a person and determining whether the sensor data exceeds a threshold. When the sensor data exceeds the threshold, a controller activates a first tactile stimulator to provide a first stimulation for a first period when the sensor data exceeds the threshold and then activates a second tactile stimulator to apply a second stimulation for a second period beginning at least commensurate with a cessation of (at the same time or overlapping) the first period. The bi-lateral stimulation is repeated for a therapeutically effective number of repetitions such that the first and second stimulations are applied bi-laterally to the body of the person without the individual perceiving a pause in stimulation between the first stimulation and second stimulation to provide the therapeutic benefit to the person.

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.
