    Biophysical Profile
    • Biophysical Profile Use of real time US to visualize fetus amd observe responses to stimuli
    • Use point system of 0-2 2 being good
    • tests:FHR to nonstress test, breathing movements, gross body movements, fetal tone, amniotic fluid volume
  33. Chapter 6
    -Dx procedures
    Non stress Test
    • noninvasive procedure, doppler is used to monitor FHR and a tocotransducer used to monitor contractions when mom feels fetus move she pushes a buttin and then the trace is marked on the contraction sheet to determine FHR to Fetal movement
    • Findings:reactive:if FHR is a normal baselinerate with moderate variablity accelerates 15 bpm for at least 15secs and occurs 2 or more times in 20min period
    • Prep: semi fowlers position.
    • anticipate CST(contraction stress test)
    • , or BPP if nonreactive
  34. Chapter 6
    -Dx procedures
    Contraction stress test
    • nipple stimulated for 2-3 minutes which causes pituitary gland to release oxytocin, stop nipple stim when experiences contraction
    • -do not hyperstim uterus
    • =no late decelerations
    • =late decelerations
  35. Chapter 6
    -Dx procedures
    • The aspriation of amniotic fluid
    • preformed after 14 weeks
    • reasons:maternal age >35
    • previous birth with a chromosome abnormality
    • parent is acarrier of chromosomal anomaly
