Thegoal of intrapartum FHR monitoring is to assess the ___________________ during labor so that timely and appropriate steps can betaken when necessary to avoid fetal hypoxic injury. |
adequacy of fetal oxygenation |
|
|
Oxygen is transported by maternal and fetal blood alongthe oxygen pathway, which includes the maternal lungs, heart,vasculature, uterus, placenta, and ________________. |
umbilical cord |
|
|
Theconsequences of interruption of fetal oxygenation can leadsequentially to: |
1. fetal hypoxemia, 2. fetal hypoxia, 3. metabolic acidosis, 4. metabolic acidemia, and eventually 5. injury or 6. death. |
|
|
Theobservation of an FHR deceleration that reaches its nadir in lessthan 30 seconds (variable deceleration) suggests: |
compression of the umbilical cord |
|
|
Alate deceleration, by definition, reaches its nadir in: |
30 seconds or more |
|
|
Historically,late decelerations have been attributed to ____________, which suggests interruption of the oxygen pathway atthe level of the uterus or placenta |
uteroplacental insufficiency |
|
|
Aprolonged deceleration can result from interruption of the oxygenpathway at:___________. |
any point. |
|
|
ModerateFHR variability or accelerations reliably exclude _________________ at the time they are observed. |
fetal hypoxic injury |
