Fetal Heart Rate Monitoring Quiz

Study Notes

Definition: Fetal heart rate monitoring (FHRM) is a method of assessing fetal well-being during pregnancy and labor.
Methods:
- External monitoring: Fetal heart rate is measured using a Doppler ultrasound device or a tocodynamometer.
- Internal monitoring: Fetal heart rate is measured using a fetal scalp electrode.
Interpretation:
- Baseline heart rate: 100-160 bpm, with a normal variability of 5-25 bpm.
- Accelerations: Temporary increases in heart rate, indicating fetal well-being.
- Decelerations: Temporary decreases in heart rate, potentially indicating fetal distress.

Definition: A non-stress test (NST) is a method of assessing fetal well-being by monitoring fetal heart rate in response to fetal movements.
Procedure:
- The mother is asked to press a button whenever she feels fetal movement.
- Fetal heart rate is monitored using a cardiotocograph (CTG) machine.
Interpretation:
- Reactive: A normal test result, indicating a healthy fetus.
- Non-reactive: An abnormal test result, potentially indicating fetal distress or a need for further testing.

Definition: Fetal movement monitoring is a method of assessing fetal well-being by tracking fetal movements.
Methods:
- Kick counts: The mother records the number of fetal movements over a set period.
- Actography: Fetal movements are monitored using a device that measures fetal activity.
Interpretation:
- Normal: 10-15 movements per hour, indicating a healthy fetus.
- Abnormal: Fewer than 10 movements per hour, potentially indicating fetal distress or a need for further testing.

FHRM is a method to assess fetal well-being during pregnancy and labor
Two methods: external monitoring using Doppler ultrasound or tocodynamometer, and internal monitoring using a fetal scalp electrode
Baseline heart rate: 100-160 bpm with a normal variability of 5-25 bpm
Accelerations: temporary increases in heart rate, indicating fetal well-being
Decelerations: temporary decreases in heart rate, potentially indicating fetal distress

Definition: a method to assess fetal well-being by monitoring fetal heart rate in response to fetal movements
Procedure: mother presses a button when she feels fetal movement, and fetal heart rate is monitored using a CTG machine
Reactive test result: a healthy fetus, indicating normal fetal heart rate in response to movement
Non-reactive test result: an abnormal result, potentially indicating fetal distress or a need for further testing
