Ctg variability definition
WebAug 3, 2024 · The computerised CTG developed by Dawes and Redman enables measuring the short-term-variation (STV) of the FHR, which cannot be assessed by the naked eye [6, 7]. STV is one of the best predictors for fetal acid-base status before labour. However, its value in the intrapartum period has not been realised. WebA CTG with a stable baseline, normal variability and accelerations is required at the start of monitoring for a confident evaluation of ST data. FIGO 2015 However, even in an …
