The massive growth in Medical Science department is providing a comfort life to human life cycle. New techniques are emerging day by day for the diagnosis of various diseases. Many of the diseases are successfully detected and cured for adults. Apart from these diseases, there is also some issues which causes sudden death. One of such issue is lack of oxygen for fetus during third trimester of pregnancy. As we already know, oxygen is the required gas for the survival of living organisms. Cardiotocography is generated by recording fetal heart rate and uterine contractions signals simultaneously and it is technically obtained from the mother’s abdominal wall. Accurate interpretation of the FHR signals is particularly important because FHR signals carry vital information to help an assessment of fetal condition. Most pregnancy period complication leads fetus to a severe drawback that restricts correct growth that causes impairment or death. Predicting pregnancy risk levels before the occasion of complications encourage correct fetal growth. The CTG features that allow the clinician to recognize a fetus who may present with an antenatal insult such as chronic hypoxia, pre-existing non-hypoxic brain injury and fetal growth. This survey will briefly address the techniques leading to intrauterine hypoxia and their impact on the fetal cardiovascular system.
