<prompt> Fetal hypoxia and acidosis are suggested by the following EXCEPTEarly decelerationLate decelerationVariable decelerationProlonged deceleration  <response>: Ans. a Early deceleration Ref. Williams obstetrics 22nd ed., p 452NONSTRESS TEST Accelerations defined as rise of acceleration to peak in 30 seconds - in FHR baseline are virtually always reassuring and almost confirm that the fetus is not acidemic at that time. Early deceleration is physiological not associated with fetal hypoxia or acidemia or low APGAR score. Peaksaccelerations are increase in FHR by _15 bpm for at least 15 seconds, it denotes healthy fetus. Deceleration is decrease in FHR below baseline by 15 bpm. Baseline variability of 5-25 bpm is a sign of fetal well-being. Reduced baseline variability is seen in:- Fetal hypoxia,- Sleep phase,- Congenital malformation and- Drug intake by mother like sedatives and antihypertensives.
