Document Summary
Non-stress test (nst) most widely used technique for antepartum evaluation of fetal well-being performed during the third trimester. It is a noninvasive procedure that monitors response of the fhr to fetal movement. Reactive: fhr is a normal baseline rate with moderate variability, accelerates to 15 beats/min for at least 15 seconds and occurs two or more times during a 20-min period. Non reactive: it does not meet the above criteria after 40 min. If this is so, a further assessment, such as a contraction stress test (cst) or biophysical profile (bpp), is indicated. A doppler transducer, used to monitor the fhr, and a toco transducer, used to monitor uterine contractions, are attached externally to a client"s abdomen to obtain tracing strips. Indications for the use of an nst during pregnancy. Assessing for an intact fetal cns during the third trimester. Ruling out the risk for fetal death in clients who have diabetes mellitus.
