area, which helps the users to record the FHR waveform and maternal heart rate waveform together.
How to set the source of maternal heart rate:
1.
Select FHR waveform area and the [FHR SETUP] menu will be displayed;
2.
Select [MHR] and select the source of maternal heart rate from [OFF], [HR], [PR] and [AUTOMATIC].
[OFF] means the function of displaying maternal heart rate waveform in the FHR waveform area will
be deactivated;
[HR] means the source of maternal heart rate is the measured maternal heart rate;
[PR] means the source of maternal heart rate is the measured maternal pulse rate;
[AUTOMATIC] means the monitor will auto select the measured maternal heart rate or pulse rate as the
source of maternal heart rate.
The users can also set the display color for maternal heart rate waveform by entering [FHR SETUP] menu
and selecting [MHR DISP COLOR].
14.2.4.2 Setting the FHR Sound Channel
FHR sound channel means which channel the FHR sound comes from. The available options include [FHR 1]
and [FHR2]. When there is only one FHR transducer connected, the FHR sound channel will be locked as
[FHR1] and when there are two FHR transducers connected, the users can select the FHR sound channel as
needs.
How to set the FHR sound channel:
1.
Select FHR1 parameter area, select [Sound channel] and select [FHR1] or [FHR2];
2.
Select FHR2 parameter area, select [Sound channel] and select [FHR1] or [FHR2];
14.3 TOCO Monitoring
The TOCO indicates the delivery strength. The uterine contraction has been clinically proven to impact the
fetal heart activities and delivery. The recorded TOCO trace provides such information as the strength,
frequency, duration, regularity and shape of uterine contraction. The uterine contraction can increase or
reduce the FHR. The monitor can monitor the TOCO of the mother in the fetus monitoring process, so the
doctor can diagnose the FHR changes as per the uterine contraction.
The external pressure monitoring is to monitor the TOCO through the mother’s abdomen. In case of any
uterine contraction, the tension of the abdominal wall will compress the TOCO transducer, which will
convert such compression into electrical TOCO signals. The electrical TOCO signals will be magnified by
the monitor for you to view or print.
