Introduction

A fetal Doppler is a handheld ultrasound device widely used during pregnancy to assess fetal health by detecting the heartbeat. This article provides a comprehensive understanding of how this technology works, including solutions provided by Leis Company.

Principles of Fetal Doppler

Fetal Doppler devices operate based on the Doppler effect, a principle that refers to the change in frequency or wavelength of a wave relative to an observer. Specifically, in fetal Dopplers, sound waves are emitted by the device and reflect off moving objects, such as the fetal heart.

The device then measures these changes in frequency, which are influenced by the motion of the heart, interpreting them to produce an audible sound or visual representation of the cardiac cycle. Typically, fetal Dopplers emit sound waves at a frequency between 2 to 3 MHz, optimal for penetrating maternal tissue and reaching the fetus without excessive attenuation.

Analyzing Fetal Heart Rate

Fetal heart rate (FHR) monitoring is crucial in evaluating the well-being of the fetus. A normal FHR ranges from 110 to 160 beats per minute (bpm). Deviations from this range can indicate potential distress or abnormal conditions, necessitating further medical evaluation.

• A rate below 110 bpm may signal fetal bradycardia.
• A rate above 160 bpm could indicate fetal tachycardia.

Regular monitoring allows for prompt intervention if abnormal patterns are detected, thus improving pregnancy outcomes.
