In the VEAL CHOP mnemonic, which deceleration corresponds to head compression?

• A. Variable decelerations
• B. Early decelerations
• C. Accelerations
• D. Late decelerations

Answer: (B)

In fetal heart rate monitoring, certain decelerations are linked to specific intrapartum events, and the VEAL CHOP mnemonic helps you connect them. Head compression during contractions triggers a vagal response that slows the fetal heart rate in a pattern that starts with the onset of a contraction and returns to baseline by the end, with the deepest point (the nadir) aligned with the peak of the contraction. This pattern is known as an early deceleration and is typically reassuring, reflecting normal head compression rather than fetal distress. By contrast, variable decelerations are due to cord compression and can occur at any time with abrupt drops, late decelerations occur after the contraction peaks and point to uteroplacental insufficiency, and accelerations are brief increases in heart rate associated with fetal movement and are also reassuring. So head compression corresponds to early decelerations.
