Thefetal monitor is part of the overall observation of the baby. It tracks the heart rate of the baby and tells us a great deal about the health of the baby as well as if the baby is under any stress.
For a fetus over 32 weeks of gestation age we expect the heart rate to e faster than 15beats per minute above the baseline and last for more than 15 second but less than 2 minutes from the time the rate changes to the time it returns to the baseline rate. In a case where the fetus is younger than the 32 weeks we expect the heart rate to peat at more than 10beats and last for more than 10 seconds but less than 2 minutes.
In a case of prolonged acceleration, where the acceleration is more than 2 minutes and less than 10 minutes we want to monitor the beat to see that it does last more than 10 minutes. In that case that would be a change of the baseline. The acceleration could be identified as either episodic or periodic. The episodic acceleration are independent of any uterine activity while periodic would be firmly related to uterine contractions.
Clearly identifying acceleration of this kind with a fetal monitor is important, since it indicates unprompted fetal activity, stimulation of some kind or uterine activity. The acceleration may be symptomatic of umbilical cord occlusion due to baroreceptor-mediated response.
With either expected or unplanned fetal heart rate increase can show a decrease or lack of fetal metabolic academia as the heart rate is observed on the monitor must be the baby and not the money for correct analysis of the data. Occasional changes in the baby’s heart rate can be caused by the umbilical cord pressing on the baby causing it stress as is worse than episodic acceleration. If the heart rate speeds up then the situation can progress to further categories. When the heart rate increases because of birthing process and scalp stimulation is not clear if that is of any significance since the baby’s heart rate is not really in a state of acceleration. The main reason is that as he mother pusher her heart accelerates and the baby’s heart rate decelerates.
