摘要
A cardiopulmonary resuscitation (CPR) monitoring device includes an invasive arterial blood pressure (iABP) transducer (20) connected with an arterial cannula or catheter (16) to measure an iABP signal (30). A CPR chest compressions sensor (14, 70, 72) measures a CPR chest compressions signal (74, 76). One or more electronic processors are programmed to: (i) extract a CPR chest compression rate from the CPR chest compressions signal; (ii) compute a CPR chest compressions component (42) of the iABP signal by fitting to the iABP signal a harmonic series whose fundamental frequency is set to the CPR chest compression rate, and (iii) compute a compressions free component (44) of the iABP signal as a difference between the iABP signal and the CPR chest compressions component of the iABP signal. A display component (51) displays at least the compressions free component of the iABP signal.
