42
Q

Early Decelerations:

A

Occurs during contractions as the fetal head is pressed against the women’s pelvis or soft tissues. It is a gradual decrease in the fetal heart rate below the baseline starting with the beginning of the contraction and ending with the contraction. They mirror the contraction. Early decelerations are caused by fetal head compression which elicits a vagal response. They are not associated with fetal compromise and do not require intervention.

Q

Variable Deceleration:

A

Can occur at any time unrelated to contractions. They are an abrupt decrease in the fetal heart rate usually with an abrupt return to baseline. Any condition that impairs blood flow through the umbilical cord can result in variable decelerations.

Q

Late Deceleration:

A

Appearance is similar to early decelerations, the fetal heart rate gradually decreases after the contraction begins and returns to baseline after the contraction is over. They represent impaired exchange of oxygen and waste products in the placenta (uteroplacental insufficiency). Prolonged uteroplacental insufficiency can lead to fetal acidosis.
