2 Introduction
The Fetal Monitor can provide different configurations according to different user requirements:
FHR1 (Ultrasonic Channel ), FHR2 (Ultrasonic Channel ),TOCO, FMOV (Fetal MovementⅠ Ⅱ
Marker). Monitoring results can be recorded by built-in recorder for continuous or intermittent
records.
The monitor can be used individually or connected with PC through RJ45 Interface for the
purpose of central monitoring.
2.1 Intended Use and Application
Fetal Monitor can acquire fetal heart rate, maternal uterine contraction when pregnancies over 28
weeks to provide reference data for clinical use.
Dual Heart Rate Monitoring allows simultaneous monitoring of two heart rates for twins. This is
achieved by using the facilities of two ultrasound transducers and an external contractions
(TOCO) transducer with a recorder.
The monitor can display FHR, TOCO, MARK (remote) sinuously, by analyzing their mutual
relations, to judge fetal physiology, pathology and maternity status, and so on, for medical
professionals reference.
It is only suitable for the equipment in hospitals, clinics, doctors offices and patients at home by

5. Monitoring
5.1 Operation Procedure
Ultrasound Transducer and TOCO Transducer Positioning showed as Figure 5.1
Figure 5.1 Ultrasound Transducer & TOCO Transducer Positioning
5.1.1 Ultrasound Monitoring of FHR
Ultrasound monitoring can be used for antepartum monitoring; it is a method to obtain FHR
through maternal abdominal wall. Put the FHR transducer on maternal abdomen to transmit lower
energy ultrasound wave to fetal heart, then receive the echo signal from it.
Operation Procedure:
Preparing the Monitor
1
Turn the monitor on and verify that the normal monitoring screen appears on the display.
Check the ultrasound transducer to verify proper attachment to the monitor. For twins monitoring,
make sure the second ultrasound transducer if properly connected.
Set the current heart rate channel to channel US1, and adjust FHR1 volume well.
Attach the buckle of the ultrasound transducer to the belt. Apply aquasonic coupling gel to the
face of the transducer.
2 Acquiring the Fetal Heart Signal
Determine the location of the fetal heart using palpation or a fetoscope.
Place the ultrasound transducer on the abdomen over fetal site and move it slowly until the
characteristic hoof-beat sound of the fetal heart is heard. And then fix up the ultrasound transducer.
The elasticity of belt can be adjusted, which make the patient monitored in the comfortable
situation, and the fetal heart rate value will be shown on the screen. At the same time, the
ultrasound wave will be drawn in green color on the screen.
3 Acquiring Twins’ Heart Rates Signal
CMS800G is able to monitoring twins’ heart rates through two ultrasound transducers during the
whole pregnant time.
Follow the step②mentioned above to acquire the heart rate for the first fetus.
Set the current heart rate channel to US2, and adjust FHR2 volume well so that the second heart
sounds can be heard
Determine the location of the second fetal signal using palpation or a fetoscope.
Attach the buckle of the ultrasound transducer to the belt. Apply aquasonic coupling gel to the face
of the transducer. Place the second ultrasound transducer on the abdomen over fetal site and move
it slowly until the characteristic hoof-beat sound of the fetal heart is heard.
The fetal heart rate value FHR2 will be shown on the screen. At the same time, the ultrasound
wave will be drawn in yellow color on the screen.
CAUTION: Do not mistake the higher maternal heart rate for fetal heart rate.
4 Monitor Adjustments:
Adjust the position of ultrasound scanner according to the need.
There is only one fetal heart sound can be heard from the speaker, change it by selecting different
channel of fetal heart sound (the first sound channel for FHR1, and the second sound channel for
FHR2)
Readjust the volume setting for the desired loudness.
Note:
The ultrasound transducer measures the FHR; the misuse of it will be result in wrong
measurement or misunderstanding of it. So it requires the doctor pay attention to it:
The best quality records will only be obtained if the transducer is placed in the optimum
①
position.
Positions with strong placental sounds (swishing) or fetal cord pulse (indistinct pulse at
②
fetal rate) should be avoided.
If the fetus is in the cephalic position and the mother is supine, the clearest heart sound
③
will normally be found on the midline below the umbilicus. During monitoring prolonged
lying in the supine position should be avoided owing to the possibility of supine hypotension.
Sitting up or lateral positions are preferable and may be more comfortable to the mother.
It is not possible to FHR unless an audible fetal heart signal is present. The fetal pulse can
④
be distinguished from the maternal pulse by feeling the mother’s pulse during the
examination.
During the monitoring, the doctor should observe the monitor screen, if the screen break
⑤
off frequently, the position of the ultrasound transducer may had out of proper position due
to the moving of the fetus.
During the monitoring, if the FHR can be heard without steadily sound of the fetal heart,

5.1.2 Monitoring Contractions
Operation Procedure:
1 Preparing the Monitor
Turn the monitor on and verify that the normal monitoring screen appears on the display.
Insert the TOCO Transducer into the socket.
Acquiring Uterine Contraction Data
2
Fix the transducer. The transducer is retained on the midline half-way between the mother’s
fundus and the umbilicus. The position is shown as figure5.1
The display of external pressure is shown as a percentage % of full scale. The uterine activity
reading at this point should be greater than 30 units and less than 90 units. If the reading falls
outside this range, the belt may be too tight or too loose.
Zero can be set more quickly by pressing the AUTO ZERO button on the front panel, provided
③
the mother is not experiencing a contraction. The default contraction data will be 10% after press
the AUTO ZERO button.
Caution: Under no circumstances are transducers to be used to monitor patients under water.

Maintenance, Care and Cleaning
6
To ensure that the monitor works properly, please read the manual and operation procedure as well
as the maintenance before using the monitor, and operate it as requested.
6.1 Preventive Maintenance
(1) Visual Inspection
The user must check that the equipment, cables and transducers do not have visible evidence of
damage that may affect patient safety or monitoring capability before use. The recommended
inspection interval is once per week or less. If damage is evident, replacement is recommended
before use.
(2) Routine Inspection
The equipment should undergo periodic safety testing to insure proper patient isolation from
leakage currents. This should include leakage current measurement and insulation testing. The
recommended testing interval is once a year or as specified in the institution’s test and inspection
protocol.
(3) Mechanical Inspection
Make sure all exposed screws are tight.
Make sure all models and connector are in proper positions.
Check the external cables for splits; cracks or signs of twisting replace any cable that shows
serious damage.
WARNING: Failure on the part of the responsible individual hospital or institution
employing the use of this equipment to implement a satisfactory maintenance schedule may
cause undue equipment failure and possible health hazards.
6.2 Care and Cleaning of Monitor
Keep the exterior surface of the monitor clean and free of dirt.
Regular cleaning of the monitor casing and the screen is strongly recommended. Use only non-
caustic detergents such as soap and water to clean the monitor casing.
Take extra care when cleaning the display surface. These are more sensitive to rough handling,
scratches and breakage than the other external surface of the monitor. Use dry, and soft cloth to
wipe.
WARNING: Unplug the monitor from the AC power source and detach all accessories before
cleaning. Do not immerse the unit in water or allow liquids to enter the casing.
CAUTION:
Many cleaners must be diluted before use. Follow the manufacturer’s direction carefully to
