Does surfactant means to keep alveoli open and helps premature babies survive?

Quite often, surfactant is not fully present in premature babies which is why they tend to need extra breathing support when they are born.
If doctors are able to hold off on the imminent birth of a premature baby, they will give the mother injections of steroids to try & speed up lung development.
Surfactant reduces the surface tension of the lungs and allows them to expand, which is important for breathing.

What do some premature babies lack which causes the alveoli to stick together when the baby exhales?
surfactant
Which surfactant lacks in a new born baby?
I have never heard the surfactant called anything specific. Full term babies usually have surfactant (a mixture of lipids (fats) and proteins). Premature babies many times do not have enough surfactant to keep the alveoli of their lungs open, so artificial surfactant is put into the trachea, sometimes more than once.
The condition of newborns called respiratory distress syndrome is caused by?
RDS is caused by deficiency of surfactant a substance which lowers surface tension and prevents the alveoli from collapsing. It is common in premature babies.
What is a phosphlolipid that lowers the surface tension of the alveoli preventing them from collapsing?
The Great (Type 2) Alveolar cells secrete pulmonary surfactant and prevent the cells from collasping.
Will human premature babies die early?
It is possible, but medical advances have made it more likely that even premature babies will survive. Long term, a premature baby is no more likely to die young than a full term baby.
Why do premature babies have respiratory distress?
Respiratory Distress Syndrom (RDS) is most common in babies born before 34 weeks of pregnancy. Babies with RDS don't have a protein called surfactant that keeps small air sacs in the lungs from collapsing.
What is intra-alveolar hyaline membrane?
A pathological condition characterized by the combination of fibrin and cellular debris, found inside the alveolar sacks of the lungs. They are the result of leakage of blood components into the alveolar sacks. They inhibit gas exhange and result in systemic hypoxia, with possible death in premature babies and symptoms of acute respiratory distress syndrome in adults. For example, neonatal respiratory distress syndrome features intra-alveolar hyaline membranes. This disease occurs in premature births. The newborn has not produced sufficient surfactant and so most of the alveoli in his/her lungs collapse. The few remaining alveoli are given the entire blood supply of the lung. Overloading of the blood vessels causes high hydrostatic pressure and eventual leakage of blood components into the alveoli supplied by the blood vessel. As these components accumulate, intra-alveolar hyaline membranes start to form. The membranes hinder the gas-exchange that would normally take place in the alveoli, leading to systemic hypoxia. This is the most common cause of death in premature babies.
Why do premature babies need caring for?
Because there lungs might not be developed enough depending on how premature a baby is the more care it will need as it might not be strong enough to survive without help xx
How many premature babies are born each year?
937 Premature babies are born each year
Respiratory disorder in the neonate?
Respiratory distress syndrome (RDS) is a common respiratory disorder in neonates, especially premature babies. It is caused by immature lung development and lack of surfactant, resulting in breathing difficulties. Treatment may include oxygen therapy, mechanical ventilation, and surfactant replacement therapy.
