the ECG rhythm, requiring the rescuer to stop CPR to assess the ECG. For example, in the case
of asystole or low amplitude PEA, the residual artifact seen after filtering may look like fine
ventricular fibrillation.
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 Propaq MD unit must be monitoring CPR.
•
ZOLL OneStep CPR pads, OneStep Complete pads, or CPR-D-padz must be attached to the
unit.
When chest compressions begin, the Propaq MD unit
automatically
starts filtering the CPR
1artifact after detecting the first 3 to 6 compressions. The filtered ECG, with the label “FIL,”
may be displayed on the second by selecting
FILT ECG
in the Trace2, Trace3 or Trace4 menu.
(If selected in the Trace3 or Trace4 menu, the filtered ECG will automatically be moved up to
the second trace.)
See-Thru CPR filtering continues as long as the OneStep CPR, OneStep Complete or
CPR-D-padz 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.
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.
