Fetal Heart Tones Strip Interpretation

Baseline = 145

Normal Range = Yes

Name ____________________________

Variability = Moderate

Accelerations present = Yes

Decelerations present = NO If yes, which variety? N/A Category = I Contraction pattern = Frequency = 2.5-4 minutes, Duration 70-80 seconds Any intervention needed = NO Notes: ________________________________________________________________

Baseline = 130

Normal Range = Yes

Variability = Moderate

Accelerations present = Yes

Decelerations present = NO If yes, which variety? N/A Category = I Contraction pattern = Frequency = 2-2.5 minutes, Duration 50-100 seconds Any intervention needed = NO Notes: ________________________________________________________________

Baseline = 195

Normal Range = NO

Variability = Moderate

Decelerations present = Yes If yes, which variety? Variable

Accelerations present = Yes

Category = II

Contraction pattern = Frequency = 3-3.5 minutes, Duration 80-140 seconds Any intervention needed = Yes Notes: Assess for maternal temp, most likely cause of fetal tachycardia. Cooling measures for mom including antipyretics. Fetal tachycardia can also be caused from stress. Think potential sepsis if ROM. Any other signs of infection? If contractions continue to be 120 seconds or longer or more than 5 in 10 minutes = uterine tachysystole, think uterine resuscitation and turn off any uterotonics.

Baseline = 150

Normal Range = YES

Variability = Minimal to Moderate

Decelerations present = Yes If yes, which variety? Variable

Accelerations present = NO

Category = II

Contraction pattern = Frequency = 2.5-3 minutes, Duration 80-90 seconds Any intervention needed = Possibly Notes: Assess cervical dilation and station, is the patient close to delivery? Attempt position change to relieve pressure on cord. Possible uterine resuscitation. If remote from delivery and variables happening greater than 50% of the time, consider amnioinfusion.

Baseline = 125

Normal Range = YES

Variability = Absent

Decelerations present = Yes If yes, which variety? Late

Accelerations present = NO

Category = III

Contraction pattern = Frequency = 3.5-4 minutes, Duration 100-120 seconds Any intervention needed = YES Notes: Action needed. Absent variability and late decelerations are consistent with fetal hypoxia and can lead to acidosis. If remote from vaginal delivery and unable to improve with uterine resuscitation measures and removing all uterotonics, prepare for cesarean delivery.

Baseline = 130

Normal Range = YES

Variability = Moderate

Accelerations present = Yes

Decelerations present = Yes If yes, which variety? Early Category = I Contraction pattern = Frequency = 3 minutes, Duration 120-140 seconds Any intervention needed = Possibly Notes: Head compression, assess patient to determine if delivery is imminent. Consider position changes.

Baseline = 105

Normal Range = NO

Variability = Minimal

Accelerations present = Yes

Decelerations present = NO If yes, which variety? N/A Category = Unable to determine Contraction pattern = Frequency = 2-3 minutes, Duration 90-110 seconds Any intervention needed = YES Notes: Maternal Vitals are available. Maternal pulse is 105, which is the same as the tracing. Go to the bedside and take radial pulse of mother while listening to fetal heart rate. Determine if the monitor is tracing maternal or fetal heart rate. Adjust fetal monitor to detect fetal heart rate.

Baseline = 125

Normal Range = Yes

Variability = Minimal

Accelerations present = No

Decelerations present = NO If yes, which variety? N/A Category = II Contraction pattern = Frequency = 3-4 minutes, Duration 80-110 seconds Any intervention needed = Possibly Notes: Assess any relevant clinical data. Assess the previous fetal heart tone strip, was it category I previously? Is the baby in a sleep cycle? Did mother recently have pain medication such as fentanyl?

Baseline = 130

Normal Range = Yes

Variability = Absent

Decelerations present = Yes If yes, which variety? Late

Accelerations present = Yes

Category = III

Contraction pattern = Frequency = 1.5 minutes, Duration 40-60 seconds Any intervention needed = Yes Notes: This pattern is consistent with an obstetric emergency; placental abruption. Assess any relevant clinical data. Perform uterine resuscitation and prepare for stat cesarean delivery. Prepare for possible hemorrhage protocol for mother. Newborn may require fluid resuscitation. Uterine tachysystole can also be caused by administration of uterotonics. Stop all medications if present.
