Abstract
A method of analyzing a physiological (e.g., an ECG) signal during application of chest compressions. The method includes acquiring a physiological signal during application of chest compressions; acquiring the output of a sensor from which information on the velocity of chest compressions can be determined; and using the information on the velocity to reduce at least one signal artifact in the physiological signal resulting from the chest compressions.
Claims27
A method of analyzing a physiological signal during application of chest compressions, the method comprising:
- acquiring a physiological signal during application of chest compressions;
- acquiring the output of a sensor from which information on the velocity of chest compressions can be determined;
- and
- using the information on the velocity to reduce at least one signal artifact in the physiological signal resulting from the chest compressions,
- wherein using the information on the velocity to reduce at least one signal artifact in the physiological signal comprises using an adaptive filter that is adjusted to remove chest compression artifacts.
