5 Remove the film on the back of the electrode and place the electrode on maternal thigh;
press it firmly in place.
6 Connect the fetal spiral electrode to the DECG cable.
7 Insert connector of DECG cable into the DECG socket of the monitor.
WARNING
Do not plug the fetal spiral electrode wire into the power socket.
CAUTION
Do not mistake the higher maternal heart rate for DECG.
NOTE:
1 If there is any doubt as to the presence of a fetal heart signal with ECG, check with
the US transducer on the patient’s abdomen or with a separate diagnostic instrument.
The presence of an audible heart sound at a rate distinct from that of the maternal
pulse is unequivocal evidence of the fetal life.
2 After the electrode is well attached, allow a few minutes for the electrode and fetal
tissue to become stabilized. It is essential that the ECG signal electrode is in good
contact with the fetal presenting part.
7.3.8 Detaching Fetal Spiral Electrode
To detach the fetal spiral electrode, rotate it counterclockwise until it is free from the fetal
presenting part. Do not pull the electrode from the fetal skin forcefully.
Dispose of the used fetal spiral electrode in a proper way. Do not use it again.
7.4 Monitoring Twin FHRs
7.4.1 Monitoring Twins Externally
To monitor twin FHRs externally, you need to connect a US transducer to US1 socket and the
second US transducer to US2 socket of the monitor. Follow the instructions described in Section
7.2 Monitoring FHR with Ultrasound to acquire FHR signals for both channels. Press
CHANNEL key to switch the FH sound from one channel to the other.
When the two US transducers are fixed, make sure FH sounds from both channels are clear, two
FHR traces and two FHR numerics are displayed on the screen.
NOTE:
To ensure that both transducers stay at the optimum location, each transducer should be
fixed with a separate belt.
