Fetal bradycardia is defined as a sustained fetal heart rate less than 110 beats per minute. Once fetal bradycardia is noted, a quick ultrasound examination of the remainder of the fetus should be performed to confirm normal fetal movement, tone, and amniotic fluid.

With a transvaginal probe, a 2- to 3-mm gestational sac can usually be seen by 5 weeks from the last menstrual period (Fig 1A). A yolk sac is usually seen by 6 menstrual weeks, or by the time the mean diameter of the sac has reached 10 mm (Fig 1B and Fig 1C).

At its widest part, the fetal skull is (on average) 9.5 cm wide. This is 3.5 cm less than the widest diameter of the pelvic inlet, and 1.5 cm less than the widest diameter of the pelvic outlet.

The normal fetal heart rate is between 120 and 160 beats per minute. Typically, an abnormally fast heart rate is over 200 beats per minute.

Your healthcare provider may do fetal heart monitoring during late pregnancy and labor. The average fetal heart rate is between 110 and 160 beats per minute. It can vary by 5 to 25 beats per minute. The fetal heart rate may change as your baby responds to conditions in your uterus.

A: Its a gravid uterus with gestation sac. Sonography can easily confirm the finding. A: CT exposure is approximately 30 mGy in abdomen and pelvis scan. Usually, patients with <50 mGy exposure may continue the pregnancy.

At 12 weeks pregnant, baby is as big as a plum. The average fetus at 12 weeks is about 2.1 inches long and .49 ounces. Now that baby's got pretty much all of their important organs, their main job is to keep on growing.

The average 17 week fetus is 7.9 inches (20.1 cm) long and weighs 6.4 ounces (181 grams) .

The mean basal heart rate of 148 bpm at a median gestation of 161 days (23 weeks) is within the 110-160 bpm normal range for viable fetusses (11). The finding of more accelerations than decelerations is in contrast to previous reports based on ultrasound recordings at this gestational age.

The fetal pole is a thickening on the margin of the yolk sac of a fetus during pregnancy. It is usually identified at six weeks with vaginal ultrasound and at six and a half weeks with abdominal ultrasound. However it is quite normal for the fetal pole to not be visible until about 9 weeks.

If it's your first pregnancy you'll probably start to show between 12 to 16 weeks. But this initial bump is not from the baby. In fact, at 15 weeks, the average fetus is 4 inches long, or about as large as an orange. So that "baby bump" isn't from the baby's size, but rather the expansion of your uterus.

Normal baseline fetal heart rate (FHR), shown at 135 beats per minute (bpm). Normal baseline rate ranges from 110 to 160 bpm for a 10-minute segment and duration ≥ 2 minutes. Excludes periodic and episodic changes, marked variability, and segments differing by ≥ 25 bpm.
