A Fetoheart Sonic Aid Doppler (Fetal Doppler) is a Class II medical ultrasound device (2-3 MHz probe) for real-time detection and audible/visual display of fetal heart rate in clinical obstetric settings from 10-12 weeks gestation. Features include handheld or tabletop console, waterproof probe, digital heart rate display (30-240 bpm), amplified speaker, headphone jack, and rechargeable battery or AC power operation. Continuous wave or pulsed wave Doppler technology with auto-correlation signal processing rejects maternal artifact. Primary clinical applications include fetal heart rate detection and monitoring during routine prenatal visits, confirmation of fetal viability in first trimester, intermittent fetal monitoring during labor, non-stress test administration, multiple gestation assessment, fetal presentation determination, and post-procedure confirmation (amniocentesis, CVS, ECV). Critical safety considerations include following ALARA principle (minimum necessary exposure), appropriate ultrasound gel use, probe pressure avoidance, infection control (probe cleaning between patients), differentiation of fetal from maternal signals, and interpretation by qualified providers. Essential equipment in outpatient obstetric clinics, hospital labor and delivery units, and prenatal care settings.
