El Nino is a climate cycle where the temperature of the Pacific Ocean changes because of movements of air and ocean currents. During this period, the trade winds in the south weaken, causing the warm water to move from the Western region to the Eastern region.
El Nino climate cycle begins when warm water in the western tropical Pacific Ocean shifts eastward along the equator toward the coast of South America.
Opposite of El Nino is La Niña when the waters of the tropical eastern Pacific are colder than normal and trade winds blow strongly than usual.
Assessment for surfactant level via lecithin/sphingomyelin (L/S) ratio in the amniotic fluid is a direct estimation of fetal maturity. The purpose of surfactant is to prevent the collapsing of the alveoli during expiration.
<h3>Lecithin Sphingomyelin Ratio</h3>
- Clinicians can evaluate fetal lung development using a number of techniques, including the Lecithin-to-Sphingomyelin Ratio (L/S ratio).
- Amniocentesis was used to obtain a sample of amniotic fluid for this biochemical test, which was first developed in the 1970s and used to assess the likelihood that the newborn will experience respiratory distress syndrome (RDS).
- The maturation of the pulmonary system advances with growing gestational age as fetal lung development happens gradually.
- Alveoli don't collapse during expiration thanks to the surfactant's impact. Phospholipids, proteins, and lipids are all components of the surfactant.
- The phospholipids' chemical makeup is significant. One phospholipid in mature surfactant is phosphatidylcholine, also known as lecithin.
