摘要:
A method of processing a raw acceleration signal, measured by an accelerometer-based compression monitor, to produce an accurate and precise estimated actualdepth of chest compressions. The raw acceleration signal is filtered duringintegration and then a moving average of past starting points estimates theactual current starting point. An estimated actual peak of the compression isthen determined in a similar fashion. The estimated actual starting point issubtracted from the estimated actual peak to calculate the estimated actualdepth of chest compressions. In addition, one or more reference sensors (suchas an ECG noise sensor) may be used to help establish the starting points ofcompressions. The reference sensors may be used, either alone or incombination with other signal processing techniques, to enhance the accuracyand precision of the estimated actual depth of compressions.
