FHR, or fetal heart rate, refers to the number of times the heartbeat of a developing fetus is observed or measured per minute. It serves as an essential indicator of the wellbeing of the unborn baby during pregnancy, labor, and delivery. FHR can be measured using various methods, including handheld Doppler devices, electronic fetal monitoring (EFM), or through specialized fetal scalp electrodes.
The normal range for FHR varies throughout different stages of pregnancy. During the first trimester, the normal range is between 90 and 110 beats per minute (BPM). As the fetus grows and develops, the FHR gradually increases. By the third trimester, the typical range is between 120 and 160 BPM. However, varying factors such as maternal activity, gestational age, and fetal health can affect the range and individual variations within normal limits.
Monitoring the FHR is crucial in obstetric care as abnormal patterns or fluctuations may indicate potential distress or complications. Medical professionals often assess the FHR during regular prenatal visits to ensure the fetal wellbeing. During labor, continuous monitoring of FHR aids in determining the progress and safety of the baby. Deviations from the normal range or irregular patterns may prompt further investigation or medical intervention to safeguard the health of both the mother and the baby.
In summary, FHR stands for fetal heart rate and refers to the number of times a fetus's heartbeat is measured per minute. It serves as an important indicator of fetal wellbeing throughout pregnancy, labor, and delivery, and allows healthcare professionals to identify any potential issues or distress.
