Troubleshooting
Printing the Waveform
You can print the MECG wave onto the trace paper. Refer to “Printing the ECG Waveform” on
page 233.
Pulse Rate from Toco MP
The maternal pulse is taken from the Toco MP or CL Toco
+
MP transducer when SpO
2
or MECG
measurements are not used or have signal loss. When the pulse rate is very low, or strong arrhythmia is
present, the pulse rate measured by the Toco MP or CL Toco
+
MP transducer may differ from the
heart rate calculated from MECG. If the mother is moving about, or began pressing during the second
stage of labor, this can cause longer gaps in the recording of the maternal pulse signal. In this case use
the SpO
2
or MECG measurement to derive the maternal heart rate.

One or more MECG leads is not
attached.
Make sure that all required leads are attached
If the wave is configured to be displayed on the
monitor, you can observe if the ECG signal is
clear, or if it shows interruptions and noise
Bad electrical contact Check positioning of the electrode, ensuring that
none are displaced
Check electrodes and replace if necessary
