FIG. 42.11 Ultrasound Parameters for the Biophysical Proile.
(A) Sonogram of amniotic luid pocket measuring 5.8 cm in vertical and
more than 1 cm across, an adequate amount to earn 2 points for amniotic
luid for the biophysical proile. (B) Fetal breathing motion is identiied
by observing the diaphragm (arrow) of the fetus in longitudinal view to
detect rhythmic inspiratory and expiratory movements. Two points are
given if the fetus has 30 seconds of continuous breathing movements
during the 30-minute exam. (C) Three-dimensional sonogram of fetus
in curled position. In the biophysical proile, points for fetal movement
are given if the fetus has at least three movements of the body or
extremities in the 30-minute period and points are given for tone if there
is at least one episode of lexion and extension. See also Videos 42.2
and 42.3.
is reported as the number of points earned over the total for the
study, which is 8 for an ultrasound BPP without NST. When a
score of less than 8 out of 8 is given, the parameter or parameters
for which no points were given should also be reported. For
example, if a fetus has normal amniotic luid volume with a
pocket of luid more than 2 cm vertical and 1 cm wide, demonstrates
adequate fetal movement and tone to obtain 2 points for
each, but does not demonstrate fetal breathing movement during
the 30-minute exam, that BPP would be reported as 6 out of 8
with 2 points deducted for lack of fetal breathing movement. In
