What is the time from the start of one contraction to the beginning of the next called?

The time from the start of one contraction to the beginning of the next is referred to as interval time. This term specifically describes the duration between contractions, which is important for monitoring labor progress. Knowing the interval time helps healthcare providers assess the frequency and regularity of contractions, which is essential for determining the stage of labor and managing delivery.

In the context of labor, understanding the interval time allows medical responders to make informed decisions regarding the management and assistance needed during childbirth. The measurement of this timing is crucial for recognizing patterns that indicate labor progression or potential complications.

Other terms, while related to labor, serve different purposes. For instance, Braxton Hicks contractions are often referred to as "false labor" and represent irregular contractions that do not indicate true labor. The refractory period generally applies to the recovery phase of muscle activity, not labor contractions. Contraction time usually refers to the duration of a single contraction, rather than the interval between contractions. Therefore, interval time is the precise term for what is being asked in the question.
