Viewing the Waveform on the Screen
Printing the Waveform
You can print the MECG wave onto the trace paper. Please refer to “Printing the ECG Waveform” on
page 161.
Pulse Rate from SpO2
If you are not monitoring MHR via MECG electrodes, but you are monitoring SpO
2
, the maternal
pulse rate is derived from the SpO
2
measurement. The pulse numeric is labeled Pulse on the screen.
Pulse Rate from Toco MP
If you are not monitoring MHR via MECG electrodes and you are not monitoring SpO
2
, but you are
monitoring using Toco MP transducers, then the maternal pulse rate is also derived from this
transducer. When pulse rate is very low, or strong arrhythmia is present, the pulse rate measured by the
Toco MP transducer may differ from the heart rate calculated from MECG. Due to motion artifacts,
arrhythmia, or individual differences in pulse signal quality on the abdominal skin, it may become
necessary to choose the MECG measurement to derive a maternal heart rate.
WARNING
• No alarm is possible when Toco MP is the source of the pulse rate.
• No QRS tone is audible when Toco MP is the source of the pulse rate.
NOTE
In rare cases it is possible to pick up a fetal signal source. When a Toco MP transducer is connected to
the monitor but not applied to the patient, the measurement may generate unexpected intermittent
Pulse readings.

5 For the FM30/50, the MECG
wave is displayed automatically
on the screen, labeled MECG. If
DECG is also being monitored
(FM30/50), and the DECG
wave is configured to On, both
waves are displayed, with the
DECG wave above the MECG
wave. The DECG wave is
labeled DECG.
