6
Inspect patient skin before applying the transducer for monitoring. If the skin quality is
poor, especially when the skin is damaged or irritated, please change a site to apply the
transducer.
7
During long-time monitoring, please inspect the application site of the transducer at least
every half an hour. If the skin quality changes, you should move the transducer to another
site.
8
Do not mistake the maternal movement for fetal movement.
9
During ultrasound fetal monitoring, performing ultrasound imaging or Doppler flow
measurements or monitoring together with ultrasound transducer of other manufacturer
may cause false FHR readings, and the trace recording may deteriorate.
10 During ambulant FHR monitoring, the chance of losing the signal or detecting the maternal
heart rate is higher than during stationary monitoring. The frequency of the patient's walk
may be detected, and mistaken for an FHR signal.
11 The movement of the pregnant woman will influence the calculation of the HR.
1
It is recommended to start printing FHR trace after clear fetal heart signal is detected and
FHR computing has stabilized.
2
If AFM is enabled, please fix the transducer with a belt, suggest to reduce maternal
movement and walking, and do not pat the abdomen.
3
Using coupling gel not approved by EDAN may reduce signal quality and may damage the
transducer. This type of damage is not covered by warranty.
7.2.1 Monitoring FHR with Ultrasound Transducer
Monitoring with F15
Parts Required
a)
Wired/wireless US transducer
b) Aquasonic coupling gel
c)
Belt
Monitoring Procedure
a)
Placing Transducer Belt
Place the transducer belts across the bed, ensuring that the belt will be around the abdomen
when it is fastened. Lay the patient on the bed.
Alternatively, the patient can take a sitting position. Arrange the belt around her abdomen.
b) Determining the Transducer Position
Determine the fetal position using Leopold's maneuvers.
Search for the location of the fetal heart. The best fetal heart signal can be obtained through
the fetal back.
Place the transducer below the navel for head presentation and place the transducer above
the navel for breech presentation.
During parturition, the fetal heart moves downward as the labor progresses. It is
recommended to move the transducer along with the fetus.
