CHAPTER 7SEE-THRU CPR (OPTIONAL)
7–2 www.zoll.com 9650-0912-01 Rev. N
Because the filtered ECG signal may contain residual chest compression and/or filtering
artifacts, a rescuer should always follow the standard procedure of stopping CPR to assess the
patient’s ECG rhythm before determining treatment.
Using See-Thru CPR
To use See-Thru CPR
The R Series unit must be monitoring CPR.
OneStep CPR or OneStep Complete electrodes must be attached to the unit.
When chest compressions begin, the R Series unit automatically starts filtering the CPR artifact
after detecting the first 3 to 6 compressions.
The filtered ECG, with the label “FIL,” may be displayed on the second or third trace (by
selecting FILT ECG in the Trace2 or Trace3 menu). See-Thru CPR filtering continues as long
as the OneStep CPR or OneStep Complete electrodes detect compressions and patient
impedance is valid. When no compressions are detected or one of the conditions noted above
occurs, See-Thru CPR filtering stops, and unfiltered ECG signals are displayed. When
compressions resume, filtering automatically restarts after 3 to 6 chest compressions.
Note: There is a delay of approximately 1/16 second between the See-Thru CPR waveform
and the Trace 1 ECG waveform.
If configured to display the CPR Dashboard, the R Series unit can also be configured to display
the filtered ECG in Trace1. When the unit is configured to display the filtered ECG in Trace1,
the softkey Disable Filt ECG appears, which you can press to disable display of the filtered
ECG in Trace1 and replace it with the unfiltered ECG. When the unit displays the unfiltered
ECG in Trace1, the softkey Enable Filt ECG appears, which can redisplay the filtered ECG in
Trace1.
Examples
The following examples show the effects of See-Thru CPR filtering on ECG signals
contaminated with CPR artifacts.
Each example includes:
ECG signal with CPR artifact.
ECG signal after the See-Thru CPR filter has removed CPR artifact.
Indication of the period during which See-Thru CPR is active.
CPR signal to show when CPR activity occurred.
