Measurement of a compression parameter for CPR on a surface

摘要

A device for the determination of at least one compression parameter during the administration of cardiopulmonary resuscitation (CPR) on a patient. The device includes a compression unit adapted to move in accordance with the chest of the patient and a surface unit adapted to move in accordance with a surface supporting the patient. The compression unit has one of a signal component and a reference component, the surface unit has the other of the signal component and the reference component. The device also includes a processor configured to determine a relative measurement between the compression unit and the surface unit using data derived from the signal component and the reference component. The processor is further configured to determine the at least one compression parameter based on the relative measurement. The determined at least one compression parameter takes into account any motion and/or displacement of the surface.

1. A device for the determination of at least one compression parameter during the administration of cardiopulmonary resuscitation (CPR) on a patient, the device comprising:
a compression unit adapted to move in accordance with the chest of the patient and configured to measure a motion of the chest, the compression unit having one of a signal component and a reference component; a surface unit adapted to move in accordance with a surface supporting the patient and configured to measure a motion of the surface, the surface unit having the other of the signal component and the reference component; and a processor configured to determine a relative measurement between the compression unit and the surface unit using data derived from outputs of the signal component and the reference component and by comparing the measured motion of the surface from the measured motion of the chest, the processor being further configured to determine the at least one compression parameter based on the relative measurement; wherein the determined at least one compression parameter takes into account at least one of any motion of the surface and any displacement of the surface.
