cardiotocograph

CTG-cardiotocograph-fetal heart rate and uterine contraction

-in 20min

1.            Normal baseline fetal heart rate

                -110-150 or

                -120-160

2.            Baseline Variability lowest to peak : 5-20 small boxes

3.            Fetal heart rate acceleration: at least 2 jump up in 20min

4.            Deceleration: abnormal ie fetal hypoxia

5.            Contraction

                -same time with deceleration=type 1 deceleration

                -contraction followed by deceleration=type 2 deceleration
