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 ...
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.
A cardiac stress test is a cardiological examination that evaluates the cardiovascular system's response to external stress within a controlled clinical setting. This stress response can be induced through physical exercise (usually a treadmill) or intravenous pharmacological stimulation of heart rate.
The CST was the first antenatal surveillance test that was developed after the development of the cardiotocograph. [4] The oxytocin challenge test was first described in 1972 [11] and was standardised in 1975 when the parameters of contraction number and frequency were given. Historically, a CST was done after a non reactive NST.
Non-invasive Non-stress test: Use of cardiotocography during the third trimester to monitor fetal wellbeing. Third trimester Non-invasive Maternal blood pressure Used to screen for pre-eclampsia throughout the pregnancy. First, second and third trimester Non-invasive Maternal weighing
The stress test can result in three outcomes: Pass, Partly Pass and Fail, based on the comparison of the quantified risks to acceptable risk exposure levels and a penalty system. Phase 3: Decision, during which the results of the stress test are analyzed according to the goal and objectives defined in Phase 1. Critical events (events that most ...
Non-selective beta blocker: NSCC: Non-squamous-cell carcinoma NSCLC: non–small cell lung carcinoma: NSD: normal spontaneous delivery (see childbirth) NSE: neurospecific enolase: NSIP: Non-specific interstitial pneumonia: NSR: normal sinus rhythm: NST: non-stress test (see cardiotocograph) NSTEMI: non-ST-elevation myocardial infarction: NSU ...
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 ]
