Technology: The device uses the Doppler effect to pick up movements (like blood flowing through the heart valves and vessels) and translates them into an audible sound, often described as a "galloping horse" sound.
Design: It typically includes a main unit with a built-in speaker and/or headphone jack, a display screen for the heart rate in beats per minute (BPM), and a separate handheld probe that is placed on the abdomen.
Portability: Fetal Dopplers are compact, lightweight, and battery-operated for easy use.
Operation: To use, a clear gel (or water/aloe vera in a pinch) is applied to the abdomen to help the probe make full contact with the skin and enhance the signal.
