As a response, the syntocinon infusion rate is reduced (and then stopped); however, the fetal heart rate drops rapidly and remains low for >3 min. Clinical examination reveals a cervix which is 2 cm dilated, and a decision is made to proceed to Caesarean section immediately. WebElectronic fetal monitoring is used to record the heartbeat of the fetus and the contractions of the mother’s uterus before and during labor. FHR baseline usually ranges from 120-160 beats per minute (bpm); however, with fetal decelerations, the heart rate usually drops about 40bpm below baseline.

WebStudies on inter- and intra-observer variability have shown that the introduction of computer-assisted classifications of CTG readings has resulted in a more reliable categorization of CTG patterns overall 37, 46. The benefit of “online” CTG analysis is that asssessment can be done almost in realtime. WebTransient increases in the fetal heart rate called “accelerations” on the cardiotocograph (CTG) trace during the intra partum period have been considered as ‘hallmarks’ of fetal wellbeing during labour. Several CTG guidelines have classified the fetal heart rate acceleration as a ‘reassuring feature”.
