The parameters for a fetal monitor typically include the following:Fetal heart rate (FHR): This parameter measures the heartbeat of the baby. The normal range for a fetal heart rate generally falls between 110-160 beats per minute.Uterine contractions: The monitor may also measure the frequency, duration, and intensity of contractions during labor. This helps healthcare providers assess the progress and efficiency of labor.Maternal heart rate and blood pressure: Monitoring the mother’s heart rate and blood pressure provides important information about her overall health during labor and delivery.Oxygen saturation: Some advanced fetal monitors also measure the oxygen saturation level in the baby’s blood. This parameter helps in assessing the baby’s well-being and oxygen supply.
So what is fetal heart rate?
The Fetal Heart Rate (FHR) parameter in a fetal monitor measures the baby’s heartbeat. It is usually displayed as a graph or numerical value on a monitor screen. To read fetal heart rate on a monitor, here’s what you need to know: FHR pattern: The FHR pattern can be categorized as baseline, variation, acceleration, deceleration, and any other variation. These patterns indicate the baby’s overall health and well-being. Baseline Heart Rate: Baseline heart rate is the baby’s average heart rate during periods of no acceleration or deceleration. Usually measurements are taken for at least 10 minutes. A normal baseline fetal heart rate ranges from 110-160 beats per minute. Baseline can also be classified as tachycardia (heart rate above 160 bpm) or bradycardia (heart rate below 110 bpm). Variability: Variability refers to fluctuations in an infant’s heart rate from baseline. It indicates the control of the fetal heart rate by the autonomic nervous system. Moderate fluctuations (6-25 bpm) are considered normal and indicate a healthy baby. Absent or minimal variation may indicate fetal distress. Acceleration: Acceleration is defined as a temporary increase in fetal heart rate, lasting at least 15 seconds, above baseline by a certain amount (eg, 15 bpm). Acceleration is a reassuring sign of fetal health. Deceleration: Deceleration is a temporary decrease in fetal heart rate relative to baseline. Various types of deceleration may occur, such as early deceleration (reflecting contraction), variable deceleration (variing in duration, depth, and timing), or late deceleration (occurring after peak systole). The pattern and character of the deceleration can indicate fetal distress. It is important to remember that interpreting FHR requires clinical expertise. Healthcare providers are trained to analyze patterns and recognize any signs of potential problems.
