who frequent are accelerations in normal pregnancy 2 accelerations per 20 min (15 beats
for 15 sec at least)
what is normal fetal HR 120-160 BPPM
decrease in fetal HR and a gradual return to baseline taking longer than 30 sec, nadir is after the
peak of the contraction late decel
abrupt decrease in the FHR by at lease 15 beats for at least 15 sec but less than 2 min
variable decel
what do variable decel indicate cord compression
