14Monitoring Uterine Activity
Externally
You can measure uterine activity externally using a Toco transducer. You can also use a Toco
+
or
Toco MP transducer for the same purpose, although they also have wider (ECG/IUP and Pulse)
capabilities.
The external Toco transducer measures the frequency, duration and relative strength of contractions,
but not their absolute intensity. Amplitude and sensitivity depend on various factors such as the
position of the transducer, the belt tension and the size of the patient.
