What should the uterine contraction value be on fetal heart monitoring to indicate a contraction?
Generally, uterine contractions are considered effective when the contraction pressure measured by fetal heart monitoring exceeds 60 mmHg.
During pregnancy, oxytocin gradually accumulates in a woman's body. Around week 14 of pregnancy, when oxytocin reaches a certain level, irregular uterine contractions may occur. At this stage, the contraction pressure is typically below 20 mmHg and lasts for a short duration. However, before labor begins, contractions usually become regular and the contraction pressure often reaches approximately 60 mmHg. These are considered effective contractions, which help promote cervical dilation and facilitate fetal delivery.
Pregnant women need to monitor uterine contractions before labor onset. When contraction values indicate effective contractions, preparations for childbirth should be made promptly, and active labor management should begin.
