Cadence Fetal Monitor User Manual
Parts Required
1) Fetal ECG cable 2) Disposable fetal spiral electrode 3) Attachment pad
Operation Procedure
1)
Perform a vaginal examination and clearly identify the fetal presenting part. Using a sterile
technique to attach the fetal spiral electrode to the fetal presenting part as described in the
Directions for Use of Fetal Spiral Electrode at this section.
Figure 5.2 Connection for fetal spiral electrode
WARNING
: Do not plug the fetal spiral electrode wire into the power socket.
2)
Fix an attachment pad at fetal ECG cable.
3)
Thoroughly clean is on patient’s thigh and ensure that it is dry. Remove the release liner
from the back of the pad. Place the pad on maternal thigh and press firmly in place (Read
Prepare the Patient's Skin Prior to Placing Electrodes at this section first).
4)
Connect fetal spiral electrode with fetal ECG cable.
5)
Switch on the power of the monitor.
6)
Insert connector of fetal ECG cable into the DECG socket at the monitor.
7)
Check setup of DECG arrhythmia logic.
The transient heart rate change that equals to or is greater than±25bpm is not recorded when
enabling the DECG arrhythmia logic. The recording will resume when beat drops within the
limits.
The monitor will display all the recorded fetal heart beats when disconnecting DECG arrhythmia
logic. If you have doubts about arrhythmia of the fetus, disconnect the DECG arrhythmia logic.
Prepare the Patient's Skin Prior to Placing 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.
Z Shave hair from sites, if necessary.
Z Wash sites thoroughly with soap and water (Never use ether or pure alcohol, because this
increases skin impedance).
Z Rub the skin briskly to increase capillary blood flow in the tissues and remove skin scurf and
grease.
Detach 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.
CAUTION
: Do not mistake the higher maternal heart rate for fetal heart rate.
