Fetal heart monitoring during pregnancy is to monitor the situation of the fetus in the uterus by using the principle of ultrasound, and it is the main detection means to correctly evaluate the situation of the fetus in the uterus. Pregnant women need to listen to the fetal heart rate at every prenatal examination from 12 weeks of pregnancy; From 36 weeks, do fetal heart monitoring once a week, generally 20-40 minutes. However, if pregnant women have adverse pregnancy history such as pregnancy-induced hypertension, diabetes, intrauterine stillbirth, or fetal growth retardation, oligohydramnios, suspected hypoxia and other adverse conditions, fetal heart monitoring should be started 32 weeks in advance.
The following are some common fetal heart monitoring methods:
1. Traditional fetal heart monitoring: the heartbeat and contraction of the fetus are recorded by placing the probe on the abdomen of the pregnant woman.
2. Portable fetal heart monitoring: use handheld devices to record the heartbeat and contractions of the fetus.
3. Home fetal heart monitoring: use home equipment to record the heartbeat and contractions of the fetus.
