Decadent fetal lung maturity ratio adult videos
This is especially important for premature babies trying Fetal lung maturity ratio expand their lungs after birth. Surfactant is a mixture of lipids, proteins, and glycoproteinslecithin and sphingomyelin being two of them.
Lecithin makes the surfactant mixture more effective. The lecithin—sphingomyelin ratio is a marker of fetal lung maturity.
The outward flow of pulmonary secretions from the fetal lungs into the amniotic fluid maintains the level of lecithin and sphingomyelin equally until 32—33 weeks gestation, when the lecithin concentration begins to increase significantly while sphingomyelin remains nearly the same.
As Fetal lung maturity ratio, if a sample of amniotic fluid has a higher ratio, it indicates that there is more surfactant in the lungs and the baby will have less difficulty breathing at birth. An L—S ratio of 2.
If preterm delivery is necessary as evaluated by a biophysical profile or other tests and the L—S ratio is low, the mother may need to receive steroids such as betamethasone to hasten the fetus' surfactant production in the lungs.
An amniotic fluid sample is collected via amniocentesis and the sample is spun down in a centrifuge at rpm for 3—5 Fetal lung maturity ratio. Thin layer chromatography TLC is performed on the supernatant, which separates Fetal lung maturity ratio the components.
Lecithin and sphingomyelin are relatively easy to identify on TLC and the predictive value of the test is good. From Wikipedia, the free encyclopedia. Cardiotocography Fetoscopy Fetal scalp blood testing Fetal scalp stimulation test.
