|
What is the normal FHR
|
120-160 BPM
|
Faster than adults
|
|
|
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.
|
They must meet the 15 x 15 window to be considered accelerations.
|
|
|
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.
|
|
|
|
What are the Nursing Interventions for variable DECELS?
|
Position change, Oxygen, bolus of IV fluids, and close monitoring
|
|
|
|
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.
