Verified Answers.
What is the purpose of fetal surveillance before birth? - answer✔-MAXIMIZE
OXYGENATION
-maximize umbilical blood flow
-support maternal coping and labor progress
-maximize uterine blood flow
-maintain appropriate uterine activity
What is Electronic fetal monitoring? why do we care? - answer✔•tool for visualizing fetal heart
rate (FHR) patterns on a monitor screen or printed tracing
•Fetal well-being (oxygenation!) during labor is gauged by response of the FHR (fetal heart rate)
with & without UCs (uterine contractions)
What are the 5 essential components of FHR - answer✔-baseline FHR, variability, accelerations,
decelerations, and changes in FHR over time.
What is Intermediate feal monitoring - answer✔•Auscultation (IA) &
Palpation (of cx's)
What is continuous fetal monitoring - answer✔Electronic Fetal Monitoring (EFM)
internal and external
External Fetal Monitoring - answer✔•Non-invasive
-"Toco"-Transabdominal - Tocotransducer for u/c
Internal Fetal Monitoring - answer✔•Invasive - Membranes must be ruptured, cervix sufficiently
dilated and presenting part low
-Spiral Electrode for FHR
-Internal Uterine Pressure Catheter (IUPC) for uterine contractions
What are the normal and pathological mechanisms that influence fetal heart rate (FHR)? -
answer✔
What are the advantages of auscultation? Disadvantages? - answer✔NEED TO GET
What are the advantages of Electronic monitoring? Disadvantages? - answer✔NEED TO GET
What can Tocotransducer not do - answer✔cannot determine tone or contractions
only IUPC can see tone
What can you assess through palpation - answer✔-The frequency, duration, tone, and intensity of
contractions
•Mild or 1+ (easily dented)
•Moderate or 2+ (can slightly indent)
•Strong or 3+ (cannot indent uterus)
Peak intensity [FHR] - answer✔•mild, moderate, strong by palpation
•with IUPC - 50-75 mm Hg, up to 110 mm Hg with pushing
Resting tone [Intensity] - answer✔•want 5-15 mm Hg, up to 20 mm Hg (with IUPC)
Frequency [FHR] - answer✔•3-5 contractions averaged over 10 minutes (we want to see)
•> than 5 = "tachysystole" (or "hyperstimulation" which is old term)
Resting time [Frequency] - answer✔at least 30 seconds between contractions
Duration - answer✔•45-60 seconds in active phase
