Decelerations represent a decrease in FHR of more than 15 bpm in bandwidth amplitude. Your program should process a The onset, nadir, and recovery of the deceleration usually coincide with the beginning, peak, and ending of the contraction, respectively.11 Early decelerations are nearly always benign and probably indicate head compression, which is a normal part of labor.15, Variable decelerations (Online Figure I), as the name implies, vary in terms of shape, depth, and timing in relationship to uterine contractions, but they are visually apparent, abrupt decreases in FHR.11 The decrease in FHR is at least 15 bpm and has a duration of at least 15 seconds to less than two minutes.11 Characteristics of variable decelerations include rapid descent and recovery, good baseline variability, and accelerations at the onset and at the end of the contraction (i.e., shoulders).11 When they are associated with uterine contractions, their onset, depth, and duration commonly vary with successive uterine contractions.11 Overall, variable decelerations are usually benign, and their physiologic basis is usually related to cord compression, with subsequent changes in peripheral vascular resistance or oxygenation.15 They occur especially in the second stage of labor, when cord compression is most common.15 Atypical variable decelerations may indicate fetal hypoxemia, with characteristic features that include late onset (in relation to contractions), loss of shoulders, and slow recovery.15. *bpm = beats per minute. The use of amnioinfusion for recurrent deep variable decelerations demonstrated reductions in decelerations and cesarean delivery overall. Relevant ACOG Resources, American College of Obstetricians and Gynecologists Bradycardia not accompanied by absent baseline variability, Absent baseline variability with no recurrent decelerations, Absence of induced accelerations after fetal stimulation, Recurrent variable decelarations accompanied by minimal or moderate baseline variability, Prolonged deceleration more than 2 minutes but less than 10 minutes, Recurrent late declarations with moderate baseline variability, Variable decelerations with other characteristics such as slow return to baseline, overshoots, or "shoulders". Fetal heart rate (FHR) may change as they respond to different conditions in your uterus. Prolonged decelerations (Online Figures K and L) last longer than two minutes, but less than 10 minutes.11 They may be caused by a number of factors, including head compression (rapid fetal descent), cord compression, or uteroplacental insufficiency. Intrapartum fetal heart rate monitoring. In case of ECM tracing w decreased or absent variability (high false + rates), you can do what ancillary tests?

Tracing patterns can and will change! For example, if it is difficult to find the heartbeat using a Doppler before 16 weeks. Sometimes a fetal heart rate is outside the normal range simply because the fetus is moving around. This system can be used in conjunction with the Advanced Life Support in Obstetrics course mnemonic, DR C BRAVADO, to assist in the systematic interpretation of fetal monitoring. Your doctor analyzes FHR by examining a fetal heart tracing according to baseline, variability, accelerations, and decelerations. Are there decelerations present? Fetal heart tracing allows your doctor to measure the rate and rhythm of your little one's heartbeat. For examples, please see the Perinatology website'sIntrapartum Fetal Heart Rate Monitoring page.
