What do variable decelerations look like?

What do variable decelerations look like?

Variable decelerations are irregular, often jagged dips in the fetal heart rate that look more dramatic than late decelerations. Variable decelerations happen when the baby’s umbilical cord is temporarily compressed.

What can cause variable decelerations?

Common causes of variable decelerations include vagal reflex triggered by head compression during pushing and cord compression such as that caused by short cord, nuchal cord, body entanglement, prolapsed cord, decreased amniotic fluid, and fetal descent.

What counts as a deceleration?

Variable deceleration-a visually-apparent, abrupt decrease in FHR below the baseline. The decrease is calculated from the most recently determined portion of the baseline. The decrease in FHR below the baseline is =15 bpm, lasting =15 seconds and =2 minutes from onset to return to baseline.

What causes late decelerations in fetal heart rate?

They are caused by decreased blood flow to the placenta and can signify an impending fetal acidemia. Typically, late decelerations are shallow, with slow onset and gradual return to normal baseline. The usual cause of the late deceleration is uteroplacental insufficiency.

How do you plot a Partogram?


  1. Begin plotting in active labor.
  2. Cervical dilatation > = 4 cm and > 2 contractions / 10 minutes.
  3. Always plot initial finding at Alert line. Note the time.
  4. Repeat P/V after 4 hours and plot the cervical dilatation.
  5. In active phase cervical dilatation should be 1 or ore than 1 cm/ hour.

How do you find prolonged decelerations?

Prolonged deceleration: a visually apparent decrease of 15 or more beats per minute below the baseline. This decrease lasts at least 2 minutes but less than 10 minutes from onset to the return to baseline (≥10 minutes is con- sidered a baseline change).

What can you do for fetal bradycardia?

If a fetus is truly compromised, it is under perfused with oxygen. First-line management therefore, and to some extent regardless of the cause of the hypoxia, should be: reposition the mother to limit cord compression and improve her blood pressure, correct the maternal blood pressure as required; and.

Is fetal bradycardia curable?

Treatment and prognosis The lower the fetal heart rate, the worse the prognosis. Heart rates of <90 bpm in the first trimester are considered to have a dismal prognosis 3,8. Transfer to a tertiary center with cardiology support is often recommended.

What happens if baby’s heart rate is low?

In severe cases of sustained low heart rate, bradyarrhythmia can be life-threatening, putting the fetus at risk of non-immune hydrops (excess fluid in multiple areas of the body) and heart failure. Generally the slower the fetal heart rate, and the earlier it occurs in pregnancy, the worse the outcome for the fetus.

What causes fetal bradycardia?

The most common causes of intrapartum bradycardia include poor uterine perfusion, maternal hypotension (e.g. after epidural placement), umbilical cord prolapse or occlusion, rapid fetal descent, tachysystole, placental abruption, or uterine rupture.

How low can a baby heart rate go while sleeping?

With activity, the heart rate may get as high as 200 beats per minute. During sleep, the heart rate can occasionally drop as low as 30-40 beats per minute.

Can stress cause low fetal heartbeat?

Stress-related changes in a pregnant woman’s heart rate and blood pressure, along with chronic anxiety, can affect the heart rate of her developing fetus, a new study concludes.

Does low heart rate mean miscarriage?

A fetal heart rate below 70 beats per minute around 6-8 weeks usually predicts a miscarriage. A fetal heart rate below 90 beats per minutes is associated with a 86% miscarriage rate, and a fetal heart rate below 120 bpm is associated with an approximately 50% miscarriage rate.

What is a normal heart rate for a 5 week fetus?

At about five weeks gestation, your baby’s heart begins to beat. At this point, a normal fetal heart rate is about the same as the mother’s: 80–85 beats per minute (bpm).

How can I make my fetus heart stronger?

Pregnant women should have regular intake of diet rich in whole grains, leafy greens and lean proteins. However, in some cases, expecting mothers may emphasize rich mineral and nutrient foods. The most critical minerals that significantly impact the fetal heart development are calcium, copper, phosphorous and thiamine.

Does bed rest help baby grow?

Some doctors suggest bed rest for conditions like growth problems in the baby, high blood pressure or preeclampsia, vaginal bleeding from placenta previa or abruption, preterm labor, cervical insufficiency, threatened miscarriage, and other problems.
