21 Monitoring Maternal Heart / Pulse Rate
230
WARNING
No alarm is possible when Toco MP or CL Toco
+
MP transducer is the source of the pulse rate.
No QRS tone is audible when Toco MP or CL Toco
+
MP transducer is the source of the pulse
rate.
The Toco MP or CL Toco
+
MP transducer signal is significantly less reliable if the patient is up
and moving about, or is pushing during the second stage of labor.
NOTE
In rare cases it is possible to pick up a fetal signal source. When a Toco MP or CL Toco
+
MP
transducer is connected to the monitor but not applied to the patient, the measurement may generate
unexpected intermittent pulse readings.
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.
WARNING
No QRS tone is audible when the CL SpO2 Pod is the source of the pulse rate.
