Switching On
Touch the On/Off touch key for about 1second when the Doppler is off, and the Doppler will display the switching on interface before switching to display the test interface .
Switching Off
Touch the On/Off touch key for about 1second when the Doppler is on, and the Doppler will be switched off.
If the Doppler is not in operation or no signal is received for 2 minutes, the Doppler will switch off automatically.

FHR Detection
Before applying the Doppler to inspect FHR, you should always check whether the Doppler is in good condition and whether there is evident damage that might affect patient’s safety and the device’s function.
If evident damage is found, stop using it at once and replace it with a good one.

Procedures to Detect FHR:
a) Have the patient lie on her back.
b) Apply appropriate amount of coupling gel to the ultrasonic transducer head of the Doppler and switch on the Doppler.
c) Palpate the patient’s abdomen gently to confirm the fetus’s position.
d) Place the Doppler on the patient’s abdomen, and move it around the fetus’s position or tilt it until a clear and rhythmic heart sound is heard and FHR numeric is stably displayed.
Note:

1. Do not mistake the maternal heart rate for fetal heart rate.
   The fetal pulse should be different from the maternal pulse, which can be measured at the wrist or neck.

2. Do not wear gloves to touch the keys. If there’s water and coupling gel on the fingers, please clean them first or the touching effect will be influenced.

How to Find the Best FH Signal:

1. The easiest way: take the position the doctor last detected for FHR as a reference and move the Doppler around the position slowly until the best FH signal is found.
2. The fetal heart position may change as the fetus moves inside the uterus. You can confirm the fetal position first according to the position of the uterus fundus in different gestational weeks.
   The clearest and loudest fetal heart sound is generally obtained when the Doppler is placed on the fetus’s back. Fetal movement is usually the movement of fetal limbs. So, if frequent fetal movement occurs at the right side of the abdomen, the fetus’s back is probably at the left side and vice versa. You can find the fetus’s back according to fetal movement’s position.
   If the fetus is in cephalic delivery position, the fetal heart is either on the right side or on the left side below the navel; if the fetus is in breech delivery position, the fetal heart is either on the right side or on the left side above the navel.

Steps to Find Fetal Heart:
Have the patient lie on back and relax >> confirm fetal position by hand >> apply coupling gel to the Doppler>> place the Doppler on patient’s abdomen and start looking for the fetal heart >> the fetal heart is found when the Doppler gives out a continuing thumping sound “boom-boom-boom”.

CAUTION

1. The Doppler’s degree of protection against harmful ingress of water is IP22. Do not immerse it in water.
2. The Doppler is delicate and sensitive. Please handle it with care and try to avoid dropping on to the ground or any hard surfaces. Any damage caused by dropping is not covered by the warranty.
3. Keep the coupling gel away from children. If swallowed, consult a physician at once.

Note:

1. The best quality of fetal heart signal is obtained only when the Doppler is placed on the best detection position.
2. Do not place the Doppler near positions where placental sound or umbilical blood flow sound is loud.
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 navel. During detection, the pregnant woman’s prolonged lying in the supine position should be avoided to reduce the possibility of supine hypotension. Putting a pillow or cushion under the patient’s head or feet can be of help.
4. It is not possible to obtain accurate FHR unless a clear 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 Doppler may warm slightly (less than 2°C (35.6°F) above ambient temperature). When NOT applied, the Doppler may slightly (less than 5°C (41°F) above ambient temperature).

After Detection

1. Switch off the Doppler.
2. Wipe the remaining gel off the patient and the probe with a clean soft cloth or tissue.

Ultrasound Intensity and Safety

Ultrasound in Medicine
The use of diagnostic ultrasound has proved to be a valuable tool in medical practice. Given its 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.
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).
Explanation of MI/TI
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 0.3 dB/cm/MHz) to the acoustic frequency.

MI = Pr, α
fawf ×CMI
CMI = 1 (MPa / MHz )

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 thermo physical 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 (1.8°F).
According to different thermo physical 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.
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: ± 12percent for intensity, ± 6 percent for pressure. Based on the hydrophone calibration report by ONDA. The uncertainty was determined within ±1 dB in frequency range 1-15 MHz.

2. Digitizer: ±0.3 percent for intensity. ± 0.15 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:±2.4 percent for intensity uncertainty, ±1.2 percent for pressure uncertainty.
   Based on the temperature variation of the water bath of ± 1ºC (1.8°F).

4. Spatial Averaging: ± 3.5 percent for intensity, ± 1.75percent 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 ± 12.73 percent for all intensity values reported, ± 6.37 percent for all the pressure values,,± 12.6 percent for the Mechanical Index, uncertainty of ±12.73% percent for power,±0.15 percent for center frequency, ±6.87%for the MI.
Prudent Use Statement
Although no confirmed bioeffects on patients caused by exposure from present diagnostic 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.
