SD5/SD6 Ultrasonic TableTop Doppler User Manual FHR Examining
- 23 -
Chapter 4 FHR Examining
WARNING
1 Always check if the main unit and the probe are in good condition prior to use.
2 To avoid inaccurate diagnosis: (a) relocate the probe for the best FHR signal as the
fetal position changes; (b) when intrauterine fetal death is doubted by using this
examination method, try to verify it with other methods.
CAUTION
Handle the probe with care. Do not drop it on hard surfaces.
The 2 MHz and 3 MHz obstetrical probes are designed for FHR examining. The 2 MHz probe is
optimized for deep penetration and is widely used in the third trimester pregnancy. The 3 MHz
probe is a general purpose probe. It has better resolution and wider detection range than the 2
MHz probe, therefore is optimized for early fetal heart detection.
Follow these procedures to perform FHR examining:
1 Feel the position of the fetus by hand to find the best position to detect the fetal heart.
2 Switch on the Doppler and the probe.
3 Apply a small amount of coupling gel to the acoustic face of probe; place the probe face at the
best position for detecting fetal heart. Angle the probe to obtain an optimum audio signal.
Adjust the volume if required.
When an audible fetal heart signal is detected, a clear fetal heart sound will be heard from the
speakers/earphone, and numeric FHR value will be displayed on the LCD.
NOTE:
1 The best quality records will only be obtained if the probe is placed in the optimum
position.
2 Positions with strong placental sounds or umbilical blood flow sound should be
avoided.
3 If the fetus is in the cephalic position and the mother is supine, the clearest heart
sound will normally be found on the midline below the umbilicus. During examining,
the pregnant woman’s 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.
4 It is not possible to obtain accurate FHR unless an audible fetal heart signal is
detected. If the calculated FHR is not in accordance with the beat of the fetal heart
sound, the fetal heart sound auscultation result shall prevail.

5 When applied to the patient, the ultrasound transducer may warm slightly (less than
8°C (14.4°F) above ambient temperature). When NOT applied, the ultrasound
transducer may reach the highest temperature of 8°C (14.4ºF).
6 Maternal heart will be detected if the probe is strongly placed on maternal vessel.
7 For SD6, the effective transmission distance between the main unit and the wireless
probe is 5 meters. It is recommended that they are positioned within this distance in
photopic vision.

known benefits for non-invasive investigations and medical diagnosis, including investigation of
the human fetus, the question of clinical safety with regards to ultrasound intensity arises.
There is no easy answer to the question of safety surrounding the use of diagnostic ultrasound
equipment. Application of the ALARA (As Low As Reasonably Achievable) principle serves as a
rule-of-thumb that will help you to get reasonable results with the lowest possible ultrasonic
output.
The American Institute of Ultrasound in Medicine (AIUM) states that given its track record of
over 25 years of use and no confirmed biological effects on patients or instrument operators, the
benefits of the prudent use of diagnostic ultrasound clearly outweigh any risks.
A3.2 Ultrasound Safety and the ALARA Principle
Ultrasound waves dissipate energy in the form of heat and can therefore cause tissue warming.
Although this effect is extremely low with Doppler, it is important to know how to control and
limit patient exposure. Major governing bodies in ultrasound have issued statements to the effect
that there are no known adverse effects from the use of diagnostic ultrasound, however, exposure
levels should always be limited to As Low As Reasonably Achievable (the ALARA principle).
A3.3 Explanation of MI/TI
A3.3.1 MI (Mechanical Index)
Cavitations will be generated when ultrasound wave passes through and contacts tissues,
resulting in instantaneous local overheating. This phenomenon is determined by acoustic pressure,
spectrum, focus, transmission mode, and factors such as states and properties of the tissue and
boundary. This mechanical bioeffect is a threshold phenomenon that occurs when a certain level
of ultrasound output is exceeded. The threshold is related to the type of tissue. Although no
confirmed adverse mechanical effects on patients or mammals caused by exposure at intensities
typical of present diagnostic ultrasound instruments have ever been reported, the threshold for
cavitation is still undetermined. Generally speaking, the higher the acoustic pressure, the greater
the potential for mechanical bioeffects; the lower the acoustic frequency, the greater the potential
for mechanical bioeffects.
The AIUM and NEMA formulate mechanical index (MI) in order to indicate the potential for
mechanical effects. The MI is defined as the ratio of the peak-rarefactional acoustic pressure
(should be calculated by tissue acoustic attenuation coefficient 0.3dB/cm/MHz) to the acoustic
frequency.

A3.3.2 TI (Thermal Index)
Heating of tissues is caused by absorption of ultrasound when the ultrasound energy is applied.
The temperature rise is determined by the acoustic intensity, exposed area and thermophysical
properties of the tissue.
In order to indicate the potential for temperature rise caused by thermal effects, the AIUM and
NEMA formulate thermal index (TI). It is defined as the ratio of the total acoustic power to the
acoustic power required to raise the tissue temperature by 1ºC.
According to different thermophysical properties of the tissue, TI is divided into three kinds: TIS,
TIB and TIC.
TIS (Soft Tissue Thermal Index): It provides an estimate of potential temperature rise in soft or
similar tissues.
TIB (Bone Thermal Index): It provides an estimate of potential temperature rise when the
ultrasound beam passes through soft tissue and a focal region is in the immediate vicinity of
bone.
TIC (Cranial Bone Thermal Index): It provides an estimate of potential temperature rise in the
cranial bones or superficial bones.
A3.3.3 Measurement Uncertainties
The uncertainties in the measurements were predominantly systematic in origin; the random
uncertainties were negligible in comparison. The overall systematic uncertainties were
determined as follows:
1. Hydrophone Sensitivity: ± 23 percent for intensity, ± 11.5 percent for pressure. Based on
the hydrophone calibration report by ONDA. The uncertainty was determined within ±1dB
in frequency range 1-15MHz.
2. Digitizer: ±3 percent for intensity. ± 1.5 percent for pressure.
Based on the stated accuracy of the 8-bit resolution of the Agilent DSO6012 Digital
Oscilloscope and the signal-to-noise ratio of the measurement.
3. Temperature: ± 1 percent
Based on the temperature variation of the water bath of ± 1 ºC.
4. Spatial Averaging: ± 10 percent for intensity, ± 5 percent for pressure.
5. Non-linear Distortion: N/A.
No effects of nonlinear propagation were observed.
Since all the above error sources are independent, they may be added on an RMS basis, giving a
total uncertainty of ± 25.1 percent for all intensity values reported, ± 12.7 percent for all the
pressure values and ± 12.6 percent for the Mechanical Index.
A3.4 Prudent Use Statement
Although no confirmed bioeffects on patients caused by exposure from present diagnostic
SD5/SD6 Ultrasonic TableTop Doppler User Manual Ultrasound Intensity and Safety

ultrasound equipment have ever been reported, the potential exists that such bioeffects may be
identified in the future. Therefore, the ultrasound should be used prudently. High levels of
acoustic output and long exposure time should be avoided while acquiring necessary clinical
information.
