What are normal Toco numbers?
|Duration of monitoring (min)||137||48.6 – 345.9|
|IUPC contractions||38.3||8 – 95|
|EHG contractions||37.7||8 – 94|
|Toco contractions||26.4||1 – 64|
How do you read a NST graph?
When you’re looking at the screen, the fetal heart rate is usually on the top and the contractions at the bottom. When the machine prints out graph paper, you’ll see the fetal heart rate to the left and the contractions to the right. Sometimes it’s easier to read printouts by looking at them sideways.
What do Toco numbers mean on Fetal monitor?
Cardiotocography (CTG) is a technical means of recording (-graphy) the fetal heartbeat (cardio-) and the uterine contractions (-toco-) during pregnancy, typically in the third trimester. The machine used to perform the monitoring is called a cardiotocograph, more commonly known as an electronic fetal monitor.
What is normal CTG?
Normal antenatal CTG trace: The normal antenatal CTG is associated with a low probability of fetal compromise and has the following features: Baseline fetal heart rate (FHR) is between 110-160 bpm • Variability of FHR is between 5-25 bpm • Decelerations are absent or early • Accelerations x2 within 20 minutes.
What Toco score is a contraction?
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 high do contractions get on Toco monitor?
During normal labor, the amplitude of contractions increases from an average of 30 mm Hg in early labor to 50 mm Hg in later first stage and 50 to 80 mm Hg during the second stage.
What should NST look like?
A non-stress test (NST) looks at your baby’s heart rate over time (usually 20 to 30 minutes, but sometimes up to an hour). The monitor has two sensors that are placed on your belly with two belts that go around your waist. One sensor detects any contractions you may be having, even those you might not feel.
How is biophysical profile scored?
The results are scores on five measurements in a 30-minute observation period. Each measurement has a score of 2 points if normal and 0 points if not normal. Some BPPs don’t include all the measurements. When all five measurements are taken, a score of 8 or 10 points means that your baby is healthy.
How high does Toco get during labor?
What is a contraction on Toco?
Women in labor are traditionally monitored with the tocodynamometer (TOCO), which is based on the pressure force produced by the contorting abdomen during uterine contractions. The contractions are measured by a pressure transducer placed on the patient’s abdomen.
What is an abnormal CTG?
An abnormal CTG has two or more features which are non-reassuring, or any abnormal features. Further information about classifying FHR traces: If repeated accelerations are present with reduced variability, the FHR trace should be regarded as reassuring.
What does a CTG show?
Cardiotocography (CTG) measures your baby’s heart rate. At the same time it also monitors the contractions in the womb (uterus). CTG is used both before birth (antenatally) and during labour, to monitor the baby for any signs of distress.
What are the different types of cardiotocography methods?
Cardiotocography (CTG) 1 Method. Simultaneous recordings are performed by two separate transducers, one for the measurement of the fetal heart rate and a second one for the uterine contractions. 2 Interpretation. A typical CTG output for a woman not in labour. 3 Accelerations. 4 Decelerations.
What kind of cardiotocography is used in labour?
Alfirevic Z, Devane D, Gyte GM, et al; Continuous cardiotocography (CTG) as a form of electronic fetal monitoring (EFM) for fetal assessment during labour. Cochrane Database Syst Rev. 2017 Feb 32:CD006066. doi: 10.1002/14651858.CD006066.pub3.
How are heart rate and uterine contractions measured in cardiotocography?
Cardiotocography sound Schematic explanation of cardiotocography: heart rate (A) is calculated from fetal heart motion determined by ultrasound, and uterine contractions are measured by a tocodynamometer (B). These numbers are represented on a time scale with the help of a running piece of paper, producing a graphical representation.
When is cardiotocography used in the third trimester?
Cardiotocography (CTG) is used during pregnancy to monitor the fetal heart and contractions of the uterus. It is most commonly used in the third trimester.
