- What is the normal FHR
- 120-160 BPM
- How is the Baseline FHR determined
- By reading a minimum of a 10 min. strip and analyzing the FHR between contractions
- What is considered fetal bradycardia
- A fetal heart rate below 120 BPM for at least 10 min.
- What are some causes of fetal bradycardia
- maternal hypotension, umbilical cord compression, drugs, fetal congenital heart block, fetal hypoxia
- What is considered fetal tachycardia
- FHR above 160 BPM for at least 10 min.
- What are some causes of fetal tachycardia
- maternal fever, drugs, fetal arrhythmia, fetal hypoxia
- Variability
- The differing rhythmicity in FHR over time. Shows up as a slight jitter in the wave.
- Does variability indicate a reassuring or non-reassurung FHR pattern.
- Reassuring
- Variability is considered to be one of the most reliable indicators of fetal-well being.
- TRUE
- Periodic changes are
- Fluctuations in response to contractions or fetal activity.
- Accelerations
- Temporary NORMAL increases in FHR usually due to fetal movement.
- Variable DECELS
- Shaped like U, V, or W, but often not consistent in shape. Caused by cord compression. FHR drops suddenly from baseline and often returns abruptly to baseline. MOST COMMON.
- What are the Nursing Interventions for variable DECELS?
- Position change, Oxygen, bolus of IV fluids, and close monitoring
- Early decelerations
- Look uniform in shape, resembling inverted uterine contractions. They are caused by head compression., are of short duration and considered benign.
- Late Decels
- FHR still down after contractionis over, slow return to baseline. Caused by uteroplacental insufficiency. Pattern is OMINOUS and requires IMMEDIATE INTERVENTION.
- Interventions for late DECELS
- Position change (left side usually best), oxygen, bolus of IV fluids, DC pitocin if running, notify MD, prepare for possible C-section, continue to monitor closely.
