Hae I. Yun, Brandon M. Wubben – This study demonstrates that POCUS using a non-piezoelectric ultrasound device was able to accurately rule in first trimester IUP in the emergency department at relatively low hCG levels, with no false positive IUPs identified. During the second and third trimesters, POCUS consistently detected fetal heart motion and had good accuracy for gestational age measurements compared to OB-US.
