  2. Fetal heart tones are representative of the fetal heart and an indicator of oxygen perfusion to the fetal brain and heart. The evaluation of fetal well-being, in determining gestational age, and in cases of threatened abortion or other abnormalities. Fetal heart tones can be heard using techniques that amplify sound1. Doppler at approximately 10 weeks fetal gestation.2. Fetoscope (fetal stethoscope) at approximately 20 weeks fetal gestation.3. Electronic fetal monitoring testing is usually done when the fetus is considered viable; around 24 weeks gestation.4. Rate between 120 and 160 beats/minute.
  3. UltrasoundA. Description Ultrasound is a noninvasive, safe technique that uses reflected sound waves as they travel in tissue to produce a picture. A clear gel is applies to the womans abdomen or transducer, and the transducer is moved along the abdomen by the examiner producing images on a screen.
