12 Überwachung der fetalen Herzfrequenz und des Kineto-CTGs mit Ultraschall
Verrauschte/fehlerhafte Signale und Ausfälle
Erläuterung Normales CTG. Das Signal fällt vorübergehend aus, wobei die fetale Kurve abgebrochen wird.
Behebung Das Ausmaß der Artefakte im CTG kann durch eine Neupositionierung des Aufnehmers oder
durch den Einsatz einer Kopfschwartenelektrode gemindert werden.

„... Among its disadvantages are the need for readjustment with maternal or fetal movements and the
following: the transducer may record the maternal pulse, it may be difficult to obtain a clear tracing in obese
women or those with polyhydramnios, artifact may be recorded, and there may be doubling or halving of
the fetal heart rate when it is outside of the normal range."
