7.3.7 DECG Monitoring Procedure
1 Perform a vaginal examination to identify the fetal presenting part.
2 Prepare the patient's skin using the procedures described in section 7.3.3 Preparing the
Patient's Skin Prior to Placing Electrodes.
3 Attach the fetal spiral electrode to the fetal presenting part using the procedures
described in section 7.3.6 Directions for Using Fetal Spiral Electrode.
4 Fix an attachment pad electrode to DECG cable.
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.
Do not plug the fetal spiral electrode wire into the power socket.
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.
7.3.7 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
