Late Deceleration Amplification Factor
Fetal heart rate (FHR) late decelerations associated with uterine contractions (UCs) are attributed to
reductions in oxygen supply from the mother. The
Late Deceleration Amplification Factor parameter
allows for greater control over the amplitude of late decelerations in conditions where they would be
expected, notably for the fetal patient with placental insufficiency. In addition, use of this parameter
allows the instructor to demonstrate late decelerations for the normal fetus in the cases of maternal
hypotension and uterine hyperactivity.
The Late Deceleration Amplification Factor is a multiplicative factor applied to the oxygen distribution
in the fetus. Values above 1.0 speed up the propagation of reduced oxygen levels from the placenta to
the fetal arteries.
Default : 1.0
Range: 1.0 – 5.0
Shoulder Dystocia
The Shoulder Dystocia parameter needs to be set to Enabled to activate the condition of Shoulder
Dystocia. When Enabled , fetal descent will be interrupted when the fetal head has been delivered and
restituted. “ Now in shoulder dystocia condition ” will be logged in the event log, and the numeric station
indicator in the Graphic widget will display >| .
When Shoulder Dystocia is Enabled , a specific maneuver can be selected that will resolve the
shoulder dystocia.
Default : Disabled
Shoulder Dystocia Resolution
The Shoulder Dystocia Resolution parameter determines what maneuver, if any, will resolve shoulder
dystocia. Six options are available: None, McRoberts, Suprapubic Pressure, Rotation of Posterior
Shoulder, Rotation of Anterior Shoulder, and Zavanelli. By default, shoulder dystocia resolution is set to
None.
The McRoberts option activates the automatic resolution of shoulder dystocia upon the detection of
the McRoberts maneuver performed correctly. Upon detection, ” McRoberts maneuver was performed ”
and “ Shoulder dystocia condition resolved ” will be logged in the event log. Once shoulder dystocia is
resolved, the fetus continues to be pushed, during the contractions, through the birth canal until
reaching the final position. At the final position, the fetus is released from the birthing mechanism and
is ready to be manually delivered.
The Suprapubic Pressure option activates the automatic resolution of shoulder dystocia when
suprapubic pressure applied. The right force needs to be applied for at least 5 seconds to resolve the
condition. Upon detection, ”
Suprapubic pressure was applied ” and “ Shoulder dystocia condition resolved ”
will be logged in the even log. Once shoulder dystocia is resolved, the fetus continues to be pushed,
during the contractions, through the birth canal until reaching the final position. At the final position,
the fetus is released from birthing mechanism and is ready to be manually delivered.
