How does sponatneous fetal movement influence FHR?
Variability
Accelerations
Tachycardia
Bradycardia
Definition 3 of 96
Visually apparent, usually symmetrical, gradual decrease and return of FHR associated with a
uterine contraction. The gradual FHR decrease is defined as one from the onset to FHR nadir of
≥30 seconds. The decrease in FHR is calculated from onset to nadir of deceleration. The nadir of
the deceleration occurs at the same time as the peak of the contraction. In most cases, the onset,
nadir, and recovery of the deceleration are coincident with the beginning, peak, and ending of
the contraction, respectively.
What is the NICHD definition of baseline rate?
What is the NICHD definition of an early deceleration?
What is the NICHD definition of normal uterine activity?
What is the NICHD definition of a prolonged deceleration?
