Abstract:
PROBLEM TO BE SOLVED: To provide a concentration measurement device and method for objectively determining whether or not chest compression is appropriately executed.SOLUTION: The concentration measurement device 1 determines the amount of temporal and relative changes (ΔcHb, ΔOHb) in total hemoglobin concentration and/or oxygenated hemoglobin concentration in the head, due to repeated chest compressions. The concentration measurement device 1 includes: a light-input unit 21 that inputs measurement light to the head; a light-detection unit 22 that detects the measurement light propagated through the head, and generates a detection signal corresponding to the intensity of the measurement light; and a CPU 14 that determines the amount of relative changes (ΔcHb, ΔOHb) on the basis of the detection signal, and removes frequency components having frequencies lower than a predetermined frequency out of frequency components included in the amount of relative changes (ΔcHb, ΔOHb) through a filtering process.
Abstract:
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.
Abstract:
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.
Abstract:
Chest compression machine systems and methods adjust the administration of patient treatment based on received physiological parameter measurements, such as a CO2 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.
Abstract:
A concentration measurement apparatus measures a temporal relative change amount (ΔcHb, ΔO2Hb) 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 (ΔcHb, ΔO2Hb) and performing a filtering process of removing frequency components less than a predetermined frequency from frequency components contained in the relative change amount (ΔcHb, ΔO2Hb).
Abstract:
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.
Abstract:
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.
Abstract:
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.

Abstract:
Systems and methods described herein relate to cardiopulmonary resuscitation (CPR) devices and systems for securing the same to hands of users. The systems and methods herein provide for a CPR assistance device, such as a CPR puck, to be releasably coupled with the hand of a user using a securing device that may be releasably coupleable to the hand of the user and/or the CPR puck. The CPR puck includes a sensor to detect a compression of the body between the chest of the subject and the hand of the user. The systems enable low-cost solutions to increase the effectiveness of CPR pucks during use and ease of use by rescuers.
