How long must a deceleration last to be considered prolonged?

A deceleration is classified as prolonged when it lasts for more than 2 minutes but less than 10 minutes. This definition is crucial for understanding fetal heart rate patterns and their implications during labor. Prolonged decelerations can indicate various potential issues, such as fetal distress or uteroplacental insufficiency, necessitating timely assessment and intervention by healthcare providers.

Recognizing this time frame allows practitioners to monitor the fetal heart rate closely, making informed decisions about the need for further evaluation or intervention to ensure the well-being of the fetus. By adhering to this specific duration, healthcare professionals can better interpret fetal monitoring data and respond appropriately to ensure optimal outcomes for both the mother and the fetus.
