Felt by the mother as quickening
Fetal movement
18-20weeks of pregnancy and peaks at 28-38 weeks
Fetal movement
Minimum fetal movement in a day
10x a day
Left recumbent position after a meal and records how many fetal movements the mother felt over the next hour
Sandovsky method
Normal is twice every 10minutes or average 10-12x/hr
Sandovsky method
count to ten
Cardiff method
The mother records the time interval it takes for her to feel ten fetal movements - usually occurs within 1hr
Cardiff method
2 methods to determine fetal movement
Sandovsky
Cardiff
Normal FHR
120-160bpm
Can be heard and counted as early as the 10-11th week of pregnancy
FHR
Diagnose pregnancy as early as 6 weeks AOG
Ultrasound
It confirms presence, size and location of placental and amniotic fluid
Ultrasound
Establish presentation and position of the fetus; Predicts maturity by measurement of the biparietal diameter
Ultrasound
Recorded as early as 11th week AOG
Electrocardiography (ECG)
Substance produced by the fetal liver that is present in both amniotic fluid and maternal serum

What does it mean when increase in maternal serum AF happens?
Indicates open spinal

Trisomy 21
In triple screening, it is considered positive in what circumstance of the indicators?
The markers of all indicators are marked low
Determine the fetus’ chromosomal condition (10-12 weeks AOG)
