Movement, heart rate and “reactivity” of heart rate to movement are measured for 20-30 minutes. If the baby does not move, it does not necessarily indicate there is a problem; the baby could just be asleep. WebA nonreactive NST had a 77.8% positive predictive value (95% CI 49.0-100) in identifying the need for neonatal transfusion.
