An example of a CPR data recording system includes a hand-held chest compression measurement device and an external computing device communicatively coupled to the hand-held chest compression measurement device. The hand-held chest compression measurement device includes a housing, a motion sensor, a communication device, a memory disposed within the housing, and a processor disposed within the housing. The processor is configured to process a signal output from the motion sensor, calculate chest compression data from the processed signal output, evaluate the chest compression data after a delay from a start of the chest compressions to identify chest compressions that satisfy a pre-determined quality criterion, record the chest compression data in the memory, and send the recorded chest compression data to the external computing device via the communication device. The external computing device is configured to enable a review of the chest compression data.

Systems and methods related to the field of cardiac resuscitation, and in particular to devices for assisting rescuers in performing cardio-pulmonary resuscitation (CPR) are described herein. The system includes an applicator device configured to provide ACD CPR treatment to a patient's chest according to a plurality of phases at least one sensor configured to be coupled to the patient's chest and to measure at least one parameter related to the ACD CPR treatment and information for determining whether at least one transition point of the ACD CPR treatment has been reached; and one or more processors configured to provide a feedback signal based on a parameter for administering ACD CPR treatment to the patient's chest according to a desired treatment protocol.

The invention relates to a device for assisting a first aider with a cardiopulmonary resuscitation of a person suffering cardiac arrest, comprising a transport housing (1), in which a sensor apparatus (4) and two adhesive electrodes (2), which are or can be connected to the sensor apparatus (4), can be stowed. The sensor apparatus (4) allows data to be acquired while the first-aid measures for resuscitation are performed. The sensor apparatus (4) comprises an adhesive (5) for attachment to the chest of the patient (3). The chest compressions, i.e. depth of compression and compression frequency, can be detected by means of a motion sensor. An interface for data transfer allows wireless communication with a mobile terminal (6). Furthermore, the sensor apparatus (4) contains a high-voltage store so that, after connection to the adhesive electrodes (2), a single defibrillation shock can be delivered.

A system for assisting cardio-pulmonary resuscitation (CPR) treatment of a patient includes a defibrillator system including a defibrillator communicatively coupled to a local computing device and configured to receive signals from treatment sensors, a patient support section, and a tilt adjuster coupled to the patient support section. The tilt adjuster is configured to communicatively couple with the defibrillator system, receive a control signal indicative of a target tilt angle from the local computing device, and automatically tilt the patient support section, around a transverse axis, to the target tilt angle in response to the control signal from the local computing device. The system also includes a chest compression device mount disposed on the patient support section and configured to adjustably secure a chest compression device to the patient support section.

The at least one processor is further configured to analyze a frequency domain transform of the digitized electrocardiogram signals, to determine a metric indicative of a metabolic state of a heart of the patient, and to accelerate or delay application of the electrical therapy based upon the metric.

A system for assisting a rescuer in providing resuscitative treatment to a victim is described. The system includes a motion sensor configured to generate motion sensor signals that are indicative of motion of the chest of the victim during chest compressions, an input device configured to receive user input indicative of a type of chest compressions, an output device, and a processor, a memory, and associated circuitry, the processor communicatively coupled to the motion sensor, the input device, and the output device and is configured to receive the motion sensor signals and the user input indicative of the type of chest compressions, determine chest compression feedback for the rescuer based on the motion sensor signals, and control the output device to selectively provide the chest compression feedback for the rescuer based at least in part on the type of chest compressions indicated by the user input.

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.

An apparatus may be configured for providing feedback to caregivers during a code blue scenario when adhered to the chest of a subject undergoing resuscitation by sensing and transmitting information associated with the code blue scenario. Such information may include one or more of vital signs of the subject during resuscitation, information associated with chest movements of the subject during resuscitation, and audio information from an environment of the subject during resuscitation. One or more processors may generate real-time feedback for communication to the caregivers during the code blue scenario based on the sensed and transmitted information.

A method for treating chest wall injuries, including rib fractures, flail chest injuries or surgical incisions. The method comprising creating a localized airtight compartment external to the chest wall and fully covering the area of injury, varying the pressure within the compartment, and providing dynamic real-time counter forces that act reciprocal to the intrathoracic pressure changes that occur during ventilation. In a preferred embodiment, the apparatus has the capability of sensing the patient's chest wall motion created by ventilation, a pressure control component capable of varying the pressure within the airtight compartment such that it opposes pressure changes within the chest. The apparatus would be particularly useful in preventing the paradoxical movement of flail chest injuries. The method would also lessen pain experienced by patients with thoracic injuries such as rib fractures and post operative suffering.

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.
