2) Determine the transducer position
Refer to the recommended position in TOCO Monitoring, and select the upper, flat area as much as possible,
ensure good contact between the three metal electrodes. The skin is a poor conductor of electricity; therefore
preparation of the patient's skin is important to facilitate good electrode contact to skin.
Wash the sites thoroughly with hospital alcohol, wet tissues and soap water. (Do not use ether or pure
alcohol, which will increase skin impedance)
Avoid using conductive substance that is easy to leave residual such as conductive paste to prepare the
skin.
3) Obtain ECG signals
Place the transducer interface end up on the above selected position and set the monitor ECG gain to X4. When
a good signal is obtained, the ECG signal with regular rhythms will appear in the ECG waveform display area,
and the wireless transducer signal quality icon will become full in 3~5s. If the ECG signal is not obvious, you
can rotate the transducer slightly in the left and right 90° range or change the placement position.The ECG
signal can only be obtained when there's good contact between the three metal electrodes and the skin, or there
will be phenomenon of bad contact or ECG leads off.
4) Fix the transducer
During long-term monitoring process, contractions, fetal movements, pregnant women's movements and
changes of abdomen profile are easy to cause the transducer to slide. In order to reduce the interference caused
by such situations, please ensure that the tightness of the belt is appropriate so that the transducer can be well
fitted to the skin.

Pré sentation
La surveillance de la FC est basée sur l'obtention du signal ECG sur l'abdomen. Les trois é lectrodes
métalliques de la gaine d'électrode MECG-R correspondent aux dé rivations R, N et L des dé rivations ECG.
Comme les électrodes sont proches les unes des autres et que l'amplitude du signal ECG obtenue est faible et
sensible aux interfé rences, il faut un bon contact entre les é lectrodes et la peau pour obtenir une surveillance
continue et pré cise.
