Web. Early decelerations in FHR are caused by head compressions (vagal stimulation), are uniform in shape, begin near the onset of a uterine contraction with its nadir at the same time as the peak of the contraction, and are benign.. . Variable decelerations are caused by umbilical cord compression and are nonuniform in shape. They are abrupt in onset … WebA large declaration can be dangerous for a number of different reasons; For any object to decelerate, a force is required and for heavy objects, large decelerations will require large forces; This is true according to Newton’s Second Law: F = ma. Where: F = force in newtons (N) m = mass in kilograms (kg) a = acceleration in metres per second ...
