You asked: What is missing from the lungs of newborn babies with infant respiratory distress syndrome?

Expand Section. Neonatal RDS occurs in infants whose lungs have not yet fully developed. The disease is mainly caused by a lack of a slippery substance in the lungs called surfactant. This substance helps the lungs fill with air and keeps the air sacs from deflating.

What is missing in premature babies with infant respiratory distress syndrome?

If a baby is premature (born before 37 weeks of pregnancy), he or she may not have made enough surfactant yet. When there is not enough surfactant, the tiny alveoli collapse with each breath. As the alveoli collapse, damaged cells collect in the airways. They further affect breathing.

What happens in infant respiratory distress syndrome?

Newborn respiratory distress syndrome (NRDS) happens when a baby’s lungs are not fully developed and cannot provide enough oxygen, causing breathing difficulties. It usually affects premature babies. It’s also known as infant respiratory distress syndrome, hyaline membrane disease or surfactant deficiency lung disease.

Which liquid is deficient in infants with respiratory distress syndrome?

What causes respiratory distress syndrome in infants?

RDS is caused by the baby not having enough surfactant in the lungs. Surfactant is a liquid made in the lungs at about 26 weeks of pregnancy. As the fetus grows, the lungs make more surfactant. Surfactant coats the tiny air sacs in the lungs and helps to keep them from collapsing (Picture 1).

Does respiratory distress syndrome go away?

It can cause babies to need extra oxygen and help with breathing. RDS occurs most often in babies born before the 28th week of pregnancy and can be a problem for babies born before 37 weeks of pregnancy. RDS typically gets worse over the first 2 to 3 days. It then gets better with treatment.

Why do C section babies have breathing problems?

Babies delivered by C-section (without labor) are more likely to have this condition. This is because without the hormone changes of labor the fluid in the lungs is still there. The baby has to work to reabsorb it after birth. Babies of moms with asthma and diabetes may also be more likely to have this condition.
