Background
Definite IUP = gestational sac containing yolk sac
- Occurs ~5.5th week
- B-HCG below Discriminatory Zone = <1,500-3,000 mIU/ml
- Consider Transabd US for IUP: >6000 mIU/ml
Endometrial mantle
- normal size > 8 mm
Fetal Heart Rate
- normal 120-160
- Use M-mode to calculate
Estimated gestational age
- can be measured by crown rump length, femur length, biparietal diameter, etc.
- depends on gestational age and quality/type of image aquired
