SOLVED (Newest 2025) How many parts are there to the fetal heart tracing (FHT)? -

Correct Answers ✅There are 2 parts:

• Fetal heart rate

Can be measured internally or externally:

• Externally - measured with a doppler
• Internally - measured with a fetal scalp electrode (FSE)
• Tocodynamoter (Toco)

Measures mom's contractions

Can measured internally or externally:

• External - measured with a skin tensometer belt ('toco' belt)
• External shows the frequency of contractions
• Internally - measured with Intrauterine Pressure Catheter

(IUPC)

• Internal shows frequency and strength of contractions

The Display - Correct Answers ✅- Upper pane = baby (fetal heart tracing)

• Lower pane = mom (uterine activity)
• Fetal heart rate is displayed numerically and by increments

of 10 bpm (ascending order)

• Uterine pressure is displayed numerically in mmHG 1 / 2

• Red lines = intervals of 1 min
• Baseline of FHR is average FHR over 10 minutes, rounded to

the nearest 5 bpm. (will always end in 5 or 0) Baseline FHR - Correct Answers ✅the average FHR over 10 minutes, rounded to the nearest 5 bpm Reactive NST - Correct Answers ✅2 accelerations in a 20 min span along with moderate variability Acme - Correct Answers ✅resting period VEAL CHOP - Correct Answers ✅V- Variable C- Cord Comphression E- Early Decels H- Head Compression A- Accelerations O - OK L- Late Decels P - Placenta insufficiency

Variability - Correct Answers ✅Variability: Fluctuations in

the FHR of 2 cycles per min. or greater

• MOST important indicator of fetal oxygen status
• Variability is caused by the interplay between sympathetic

and parasympathetic systems
