Non stress test (NST) of a multigravida who is diabetic, shows late deceleration. All of the following are TRUE about late deceleration, EXCEPT:
Correct Answer: Head compression
Description: Late Deceleration: The fetal hea rate response to uterine contractions can be an index of either uterine perfusion or placental function. A late deceleration is a smooth, gradual, symmetrical decrease in fetal hea rate beginning at or after the peak of the contraction and returning to baseline only after the contraction has ended. In most cases, the onset, nadir, and recovery of the deceleration occur after the beginning, peak, and ending of the contraction, respectively. The magnitude of late decelerations is rarely more than 30 to 40 beats/min below baseline and typically not more than 10 to 20 beats/min. Late decelerations usually are not accompanied by accelerations. Ref: Cunningham F.G., Leveno K.J., Bloom S.L., Hauth J.C., Rouse D.J., Spong C.Y. (2010). Chapter 18. Intrapaum Assessment. In F.G.
