What is cardiotocography?
Cardiotocography is a type of medical test performed during pregnancy, which records contractions of fetal heart rhythm and uterus. Using a technological device called a cardiotocograph or an electronic fetal monitor (EFM), this obstetric test is commonly performed during the third trimester of pregnancy. When a cardiotocograph is used during the work process, it is referred to as a stress test.
Orvan Hess first launched preliminary research on the development of cardiotocography as early as the 1930s. At the end of 40. Hess joined with Dr. Edward Hurry to support his attempts to develop a form of technology that could notice the signals of a fetal heart. In 1957, both doctors used the first cardiotocograph to monitor the heart rhythm of the child in the uterus . Test processes have been improved during the 1960s and soon became a standard tool used in vans around the world.Line at work - while others record the contractions of the mother's uterus. Tests can be performed by internal or external methods. During internal testing, the catheter is placed in the uterus after a specific amount of dilatation. In external tests, a few sensory nodes are attached to the mother's stomach. Among them, internal measurements are considered to be a more accurate option.
Advances in technology have made it possible to store cardiotocography data on computers. In many cases, data is accessible through computer networks that allow remote mother and child observation. Cardiococography answers can also be printed and stored in the mother's medical files.
Cardiotocography is closely related to other fetal testing procedures. Biophysical Profile is done when the NEBRASS test indicates possible problems. Biophysical profile includes testing of fetal breathing, movement and tone, as well as the volume of amniotic fluid. Another diagnosisThe Sticky tool is a fetal stethoscope that is used to monitor fetal heart rhythm and is often used as a preliminary tool before prescribing cardiotocographic processes.
, which sometimes mentions the abbreviation CTG, cardiotocography can alert health workers to the possibility of fetal distress. With this technology, doctors and nurses can better measure the condition of the fetus and can carefully monitor any changes in heart rhythm that could signal complications. They can also measure the time between contractions to better determine the delivery time.
