A nonstress test (NST) is a screening test used in pregnancy to assess fetal status by means of the fetal heart rate and its responsiveness. A cardiotocograph is used to monitor the fetal heart rate and presence or absence of uterine contractions. The test is typically termed "reactive" (also "reassuring") or "nonreactive" (also "nonreassuring ...
Vibroacoustic stimulation is typically used during a nonstress test (NST). [ 1 ] [ 2 ] In 2013, the Cochrane Database of Systematic Reviews concluded that there was insufficient evidence from randomized trials to support its use to assess fetal well-being in labor. [ 3 ]
A contraction stress test (CST) is performed near the end of pregnancy (34 weeks' gestation) to determine how well the fetus will cope with the contractions of childbirth.The aim is to induce contractions and monitor the fetus to check for heart rate abnormalities using a cardiotocograph.
NST is typically monitored for at least 20 minutes. Signs of a reactive (normal) NST include a baseline fetal heart rate (FHR) between 110 and 160 beats per minute (bpm) and 2 accelerations of FHR of at least 15 bpm above baseline for over 15 seconds. Vibroacoustic stimulation and longer monitoring may be needed if NST is non-reactive. [28]
A biophysical profile (BPP) is a prenatal ultrasound evaluation of fetal well-being involving a scoring system, [1] with the score being termed Manning's score. [2] It is often done when a non-stress test (NST) is non reactive, or for other obstetrical indications. The "modified biophysical profile" consists of the NST and amniotic fluid index ...
Fetal distress, also known as non-reassuring fetal status, is a condition during pregnancy or labor in which the fetus shows signs of inadequate oxygenation. [1] Due to its imprecision, the term "fetal distress" has fallen out of use in American obstetrics.
Footage of a CTG test. Cardiotocography (CTG) is a technique used to monitor the fetal heartbeat and uterine contractions during pregnancy and labour.The machine used to perform the monitoring is called a cardiotocograph.
A companion 501(c)(6) organization, the American Congress of Obstetricians and Gynecologists, was founded in 2008 and became operational in 2010. [2] The two organizations coexist, and member individuals automatically belong to both. [3] Both are not-for-profit. [3]
