What do the numbers mean on a contraction monitor?
These are beats per minute (bpm), which are measured in increments of 10 with markings every 30 beats. The red indicator on the bottom tracing shows the strength of a contraction, measured in millimeters of mercury (mmHg). 6 The higher the number, the stronger the contraction.
How do you know if a contraction is CTG?
The fetal heart rate and the activity of the uterine muscle are detected by two transducers placed on the mother’s abdomen, with one above the fetal heart to monitor heart rate, and the other at the fundus of the uterus to measure frequency of contractions.
What is a good contraction number?
The intensity of Braxton Hicks contractions varies between approximately 5-25 mm Hg (a measure of pressure). For comparison, during true labor the intensity of a contraction is between 40-60 mm Hg in the beginning of the active phase.
How many Toco is a contraction?

Does CTG harm baby?
Are there any side-effects or complications from cardiotocography? CTG does not use any radiation; it is considered a very safe test. Depending on the machine used, it may prevent you from being able to move around freely during labour.
Why is a partogram important?
A partograph is a tool used to monitor labor and prevent prolonged and obstructed labor focusing on observations related to maternal, fetal condition and labor progress.
What does a partogram record?
The partograph is designed for recording maternal identification, fetal heart rate, colour of the amniotic fluid, moulding of the fetal skull, cervical dilatation, fetal descent, uterine contractions, whether oxytocin was administered or intravenous fluids were given, maternal vital signs and urine output.
