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: The best quality records will only be obtained if the probe is placed in the optimum position. Positions with strong placental sounds or umbilical blood flow sound should be avoided. 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. - 23 - SD5/SD6 Ultrasonic TableTop Doppler User Manual FHR Examining 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. - 24 - SD5/SD6 Ultrasonic TableTop Doppler User Manual Recording and Playing Chapter 5 Recording and Playing The built-in recorder of the Doppler allows recording and playing fetal heart sound of 240 seconds (at most).

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. 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. - 39 - SD5/SD6 Ultrasonic TableTop Doppler User Manual Ultrasound Intensity and Safety MI = Pr, α fawf × CMI CMI = 1 (MPa / MHz ) 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 - 40 - 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.
