Abstract: This disclosure relates to methods, devices and systems for real-time recognition of restoration of spontaneous circulation (ROSC) in cardio-pulmonary resuscitation (CPR) process. Recognition mechanisms in both time domain and frequency domain are provided for the ROSC recognition, where the time-domain recognition logic may detect the ROSC by recognizing envelope features of sampled signals in the time domain, and the frequency-domain recognition logic may detect the ROSC by recognizing spectral peaks at different frequency points continuously or significant variations of amplitude of spectral peaks in the frequency spectrum.

Abstract: 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 H2O, 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.

Abstract: The present invention provides a portable guidance device for cardiopulmonary resuscitation, which comprises a tri-axial gravity sensing element, a pressure sensing element, a sound output element, a visual output element and a microcontroller. The portable guidance device for cardiopulmonary resuscitation can actively connect to the medical rescue system and issue an alarm to guide the surrounding passers-by to perform real-time rescue and perform correct cardiopulmonary resuscitation, so as to improve the efficiency and accuracy of chest compressions.

Abstract: An adjustable chest compression device that can adjust to accommodate a variety of patient sizes. The chest compression device can include adjustable support legs structured to support the chest compression mechanism at a distance from the base member and adjust to accommodate a patient size. Another adjustable chest compression device can include adjustable legs that can adjust to accommodate different patient sizes, as well as perform the chest compressions using the adjustable legs. An extension, such as a back plate and/or leg extension can be added to a chest compression device to make the chest compression device taller and/or wider to accommodate larger patients.

Abstract: A method to improve neurologically-intact survival rates after cardiac arrest may include performing CPR on an individual in cardiac arrest while the individual is in a supine position in general alignment with a horizontal plane. The method may include elevating the individual's head, shoulders, and heart relative to the individual's lower body while the individual's lower body remains generally aligned with the horizontal plane to cause blood to actively drain venous blood from the brain to reduce intracranial pressure. The method may include performing chest compressions on the individual and actively decompressing the individual's chest while the individual's head, shoulders, and heart are elevated.

Abstract: A mechanical chest compression system for performing cardiopulmonary resuscitation includes a resuscitation device and a controller operatively coupled to the resuscitation device. The resuscitation device includes a base, a contact portion configured to be in a superposed relation with an anterior surface of a patient when the patient is disposed on the base, and a force sensor configured to generate a force signal during compression and decompression of the anterior surface of the patient. In particular, the contact portion is movable relative to the base to provide compression and decompression to the anterior surface of the patient. The controller includes a processor configured to receive the force signal generated by the force sensor; estimate chest compliance relationship using the force signal; and generate instructions using the chest compliance relationship to drive the contact portion to provide compression and decompression to the anterior surface of the patient.

Abstract: There is provided an apparatus (12) for use in measuring blood pressure. The apparatus (12) comprises a processor (102) configured to acquire a signal indicative of pressure oscillations detected inside a cuff inflated to pressurize a measurement site of a subject undergoing cardiopulmonary resuscitation. The pressure oscillations detected inside the cuff are indicative of a pulse of the subject. The processor (102) is also configured to trigger a blood pressure measurement for the subject based on the pressure oscillations detected inside the cuff.
