___ is one of the most important characteristics of the FHR.
variability
FACT:
If roughness is present in the baseline, short-term variability is present; if smoothness is present, it is absent.
FACT:
The presence of short-term variability typically indicates a well-oxygenated fetus
FACT:
Loss of variability may be associated with a poor outcome.
FACT:
Causes of decreased variability include fetal hypoxia/acidosis, drugs that depress the CNS, congenital abnormalities, fetal sleep, prematurity, and fetal tachycardia
FACT:
Fetal accelerations are transitory increases in the FHR above the baseline associated with SNS stimulation.
FACT:
Fetal accelerations provide evidence of fetal well-being and is generally considered reassuring and requires no interventions. Accelerations denote fetal movement and fetal well-being and are the basis for nonstress testing.
FACT:
A deceleration is a transient fall in FHR caused by stimulation of the parasympathetic nervous system.
___ are caused by fetal head compression.
early decelerations
FACT:
Early decelerations are not indicative of fetal distress and do not require intervention.
FACT:
Late decelerations are transitory decreases in FHR that occur after a contraction begins. The FHR does not return to baseline levels until well after the contraction has ended.
FACT:
Late decelerations imply some degree of hypoxia.
FACT:
Repetitive late decelerations and late decelerations with decreasing baseline variability are nonreassuring signs.
___ are associated with cord compression.
variable decelerations
___ are the most common deceleration pattern found in the laboring woman and are usually transient and correctable.
variable decelerations
Nonreassuring patterns include:
-Prolonged later decelerations
-Absent or minimal variability
-Bradycardia
-Tachycardia
-Prolonged variable decelerations lower than 60 bpm
