Modern-day CTG was developed and introduced in the 1950s and early 1960s by Edward Hon, Roberto Caldeyro-Barcia and Konrad Hammacher. The first commercial fetal monitor (Hewlett-Packard 8020A) was released in 1968. [1] CTG monitoring is widely used to assess fetal well-being by identifying babies at risk of hypoxia (lack of oxygen). [2]
A nonstress test can be classified as normal, atypical, or abnormal. A normal nonstress test will show a baseline fetal heart rate between 110 and 160 beats per minute with moderate variability (5- to 25-interbeat variability) and 2 qualifying accelerations in 20 minutes with no decelerations.

A method of external (noninvasive) fetal monitoring (EFM) during childbirth is cardiotocography (CTG), using a cardiotocograph that consists of two sensors: The heart (cardio) sensor is an ultrasonic sensor, similar to a Doppler fetal monitor, that continuously emits ultrasound and detects motion of the fetal heart by the characteristic of the ...

Nuchal cord, when the umbilical cord is (tightly) around the neck of the fetus [2]; Entanglement of the cord [2]; Knot in the cord [2]; Cord prolapse, where the umbilical cord exits the birth canal before the baby, which can cause cord compression.
Intrauterine hypoxia can be attributed to maternal, placental, or fetal conditions. [12] Kingdom and Kaufmann classifies three categories for the origin of fetal hypoxia: 1) pre-placental (both mother and fetus are hypoxic), 2) utero-placental (mother is normal but placenta and fetus is hypoxic), 3) post-placental (only fetus is hypoxic).
Types 1 and 2 are classified as minor placental praevia as these typically result in minor antepartum haemorrhaging. Types 3 and 4 are referred to as major placental praevia due to the risk of heavy haemorrhaging in the case of a rupture due to the location of placental attachment. [7]
