Abstract: An automated cardiopulmonary resuscitation (ACPR) device includes a compression element for acting on a compression location on a chest of a patient, and an optical alignment aid configured and arranged for projecting, at least temporarily, a light pattern on the patient's chest. The light pattern projected by the optical alignment aid guides the user during the placement procedure of the ACPR device. The light pattern projected by the optical alignment aid allows the user to monitor whether the position of the automated cardiopulmonary resuscitation device has moved during the administration of CPR.

Abstract: A cardio-pulmonary compression system includes a compression device (110), a supporting mechanism (120) coupled to the compression device and a feedback sensor (104) configured to measure interactions between a patient and the compression device. A control unit (112) is configured to receive input from the feedback sensor and adjust operating parameters of the compression system to meet a target parameter during operation of the compression device.

Abstract: A method for automated CPR includes controlling a position of a compression element during movement of the compression element from an initial starting position (P0) of a first compression cycle to a first compression position (P1) corresponding to a first compression depth and back to a rest position of the compression element. After, the rest position has been reached, the method includes controlling a force exerted on the compression element, to ensure that the compression element stays in contact or re-contacts with the chest while allowing the chest to move upward due to ventilation, prior to the start of a second compression cycle.

Abstract: According to the invention, a compression depth sensor for measuring a compression depth comprises a first pressure transducer (30), attachable to a fixed element, a first liquid filled lumen (20), having a first fixed lumen end (21) attachable to the pressure transducer and a first movable lumen end (22) being movable between a first position and a second position, a distance between the first and second position defining the compression depth, whereby the first pressure transducer is adapted to measure the compression depth by measuring a change in liquid pressure in the lumen during movement of the first movable lumen end between the first position and the second position. A CPR apparatus according to the invention comprises such a compression sensor.

Abstract: The invention relates to a device configured for tracking e.g. the diastolic blood pressure in a patient. The device applies a pressure to a body part, e.g. by use of an inflatable cuff. By performing repeated and alternating pressure changes in the cuff a specific feature of a signal that relates to the diastolic blood pressure can be tracked and possibly measured.

Abstract: The present invention relates to a system for providing feedback regarding chest compressions in CPR, an automated resuscitation device and method for providing feedback regarding chest compressions in CPR.

Abstract: A CPR assistance system comprises a sensor for making a physiological measurement to generate a sensor signal which conveys information concerning the point in time at which venous return is completed. Time points are then determined at which CPR compression cycles should be administered, and output information is provided relating to the determined time points. The output information may be visual or audible advice to a person giving CPR or it may be control information for controlling an automated CPR system.

Abstract: Proposed is a Pulse Transit Time, PTT, measurement concept wherein a forced oscillation technique, FOT, is used to determine a pulse arrival time at alveoli of the lungs of a patient.

Abstract: The present invention relates to an apparatus (10) for performing cardiopulmonary resuscitation comprising a resuscitation device configured for autonomously performing cardiopulmonary resuscitation, a stimulation device (12) configured for stimulating the endothelial function including nitric oxide synthase pathway in a patient in need thereof, and a controller for controlling the resuscitation device and/or the stimulation device.

Abstract: Initial setup of a Cardio Pulmonary Resuscitation device (100) is to be accomplished so that a contact pad (102) of the device makes the correct contact with the chest before the device starts giving chest compressions to the patient. Thereby situations where the contact pad is not in initial contact with the chest or situations where the contact pad initially compresses the chest too much are avoided. The position of the contact pad is measured during initial setup, and when contact between the chest and the contact pad is established, the actual position of the contact pad is measured and set as an initial position. Then a positioning range is set relative to the initial position. Therefore, the CPR device is provided with a positioning aid (131) which informs the rescuer when the contact pad is within the positioning range or when the contact pad is outside the initial positioning range.

Abstract: A method for automated CPR is disclosed. The method comprises controlling a position of a compression element during movement of the compression element from a first starting position (P0) of a first compression cycle to a first compression position (P1) corresponding to a first compression depth and back to a rest position of the compression element, and after the rest position has been reached, controlling a force exerted on the compression element until a second compression cycle starts. A computer program product comprises a non-transitory computer-usable medium having control logic stored therein for causing a transceiver to execute a method for automated CPR.
