Antepartum Flashcards
What week that the fetal movement has a passive unstimulated fetal activity commence
7 weeks
What is the goal of Antepartum assessment
Goals:
To prevent fetal death
To avoid unnecessary interventions
What week that fetal body movements are never absent for time periods exceeding 13 minutes
> 8 weeks
General body movements become organized and the fetus starts to show rest activity:
20-30 weeks
Fetal movement maturation continues until about ____, when behavioral states are established in 80 percent of normal fetus
Third trimester
36 weeks
4 states of behavioral states
State 1F, 2F, 3F, and 4F
The quiescent state with a narrow oscillatory bandwidth of the fetal heart rate
State 1F
Includes frequent gross body movements, continuous eye movements, and wider oscillation of fetal heart rate
State 2F
This states is analogous to rapid eye movement or active sleep in the neonate
State 2F
Includes continuous eye movements, absence of body movements and NO accelerations of fetal heart rate
State 3F
The existence of this state is disputed
State 3F
One of the vigorous body movement with continuos eye movements and fetal heart rate accelerations
State 4F
This state corresponds to the awake state in infants
State 4F
Fetuses spend most of their time
States 1F and 2F
The sleep awake cycles of infants are ____ of the maternal sleep awake state
