An ambulatory medical device is provided. The ambulatory medical device includes at least one sensor configured to acquire physiological data of a patient, at least one network interface and at least one processor coupled to the at least one sensor and the at least one network interface. The at least one processor is configured to detect, via the at least one network interface, a medical device, to establish a secure communication session with the medical device via the at least one network interface, to detect a data capacity of the secure communication session, to identify a category of patient data associated with the data capacity, and to transmit patient data of the category to the medical device via the secure communication session.

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.

An external defibrillator system is provided. The system includes: a graphical display; one or more sensors for obtaining data regarding chest compressions performed on a patient; and a controller configured to display on the graphical display numeric values for depth and/or rate of the chest compressions based upon the data from the one or more sensors. A method for using an external defibrillator including the steps of: obtaining data regarding chest compressions performed on a patient; and displaying on a graphical display screen of the defibrillator numeric values for depth and/or rate of the chest compressions based upon the data is also provided.

A manual cardiopulmonary resuscitation device for delivering chest compressions to a patient needing CPR. The device includes a handle, a deformable housing filled with foam, and a bottom plate. The deformable housing includes a first end coupled to the handle and a second end coupled to the bottom plate.

Devices and methods for compressing a chest of a patient includes a platform for placement under a thorax of the patient, a compression belt for extending over an anterior chest wall of the patient, a drive train operably connected to the compression belt, a motor operably connected to the compression belt through the drive train, and a control system configured to control operation of the motor to cause the drive train to tighten and loosen the compression belt in repeated cycles of compression about the thorax of the patient. Each cycle of the repeated cycles includes tightening the compression belt around the chest of the patient after tightening, causing, by the control system, the motor to cease operation of the drive train for a hold period; and at a termination of the hold period, loosening the compression belt around the chest of the patient.

An automated resuscitation system is provided, which can improve the outcome of patients suffering ventricular fibrillation or the ventricular tachycardia variants of cardiac arrest. This outcome can be achieved by a device that integrates automatic mechanical or pneumatic capability with electrical countershock capability such that the probability of defibrillation or cardioversion with return of spontaneous circulation is increased.

An ECG signal processing system which removes the CPR-induced artifact from measured ECG signals obtained during the administration of CPR.

A cardiopulmonary resuscitation support device for assisting a rescuer with cardiopulmonary resuscitation using chest compressions, including: a pressure detecting device provided with a pressure sensor including a pressure sensing part which is configured to be overlapped on a chest, the pressure sensing part having a sheet form and being capable of flexural deformation in a flexible manner; and a displacement detecting device provided with a displacement sensor to detect a displacement of a hand of the rescuer compressing the chest, the displacement detecting device being configured to be retained by the hand of the rescuer at a part away from a chest compression surface.
