Variable Decelerations Vs Late Decelerations Learn how to monitor fetal heart tone of early, late, and variable decelerations during labor. see examples, causes, and nursing interventions for each type of deceleration. Variable decelerations appear morphologically different from either early or late decelerations. they are characterized by a sudden, abrupt drop in the fht along with usually a similarly abrupt return to baseline.

Variable Decelerations Trialquest Inc Early decelerations are benign and uniform in shape. they begin near the onset of a uterine contraction, and their lowest point occurs at the same time as the peak of the contraction. late decelerations are also uniform in shape; however, their onset and return to baseline are gradual. Early decelerations appear to be a vagally mediated response to improve cerebral perfusion triggered by an intracranial baroreflex [58, 62]. late decelerations are brought about by the periodic reduction in perfusion of the intervillous space by uterine contractions. Variable decelerations are caused by direct umbilical cord compression, which leads to fetal hypertension and a subsequent decrease in fetal heart rate. late decelerations following the uterine contraction result from uteroplacental insufficiency. While early decelerations are usually normal, late and variable decelerations can point to a problem. early deceleration describes the symmetrical decreases and return to normal of the fetal heart rate that is linked to uterine contractions. the decrease in heart rate occurs gradually.

While early decelerations are usually normal, late and variable decelerations can point to a problem. early deceleration describes the symmetrical decreases and return to normal of the fetal heart rate that is linked to uterine contractions. the decrease in heart rate occurs gradually. Accurate historical information on fetal status and the frequency duration of contractions from earlier in labor. insight into the stresses on the fetus and its ability to tolerate those stresses. There are three basic types of decelerations: early decelerations, late decelerations, and variable decelerations. early decelerations are generally normal and not concerning . To facilitate separation of benign from potentially pathological decelerations, their categorization into early, late and variable has been practiced for half a century. Variability in the fhr during labor is a sign of fetal well being or fetal activity or both. the expected variability usually includes slight accelerations and decelerations. however, there are three main deceleration patterns that are important to monitor and differentiate.
