How does the test for fetal lung maturity work?
A doctor has provided 1 answer
Yes: Stress and duration in utero prepare the lungs to stay open using surfactant. Respiration not needed in utero, mom and placenta do the work. The amnio and ratio forecast how able the lungs are to deal with ambient atmosphere and pressure to respire normlly.
