Surfactant

Surfactant: A fluid secreted by the cells of the alveoli (the tiny air sacs in the lungs) that serves to reduce the surface tension of pulmonary fluids; surfactant contributes to the elastic properties of pulmonary tissue.

Surfactant is normally released into the lung tissues where it helps lower surface tension in the airways. This helps keep the lung alveoli (air sacs) open. When there is not enough surfactant, the tiny alveoli collapse with each breath.

SurfactantA material normally produced in the fetal lungs in the last months of pregnancy, which helps the air sacs to open up at the time of birth so that the newborn infant can breathe freely.

Additives such as surfactants are also used in tampons to increase absorbency. Surfactants and fragrances may pose additional unnecessary health risks when used in feminine hygiene products.

An artificial lung surfactant is sometimes delivered through an endotracheal tube into the lungs of an infant at high risk for respiratory distress syndrome immediately after birth.

Betamethasone and dexamethasone cause an immature fetus's lungs to produce a compound called surfactant. A full-term baby's lungs naturally produce surfactant, which lubricates the lining of the air sacs within the lungs.

They have, however, discovered genetic alterations in surfactant proteins — substances in the airways and air sacs that protect the lungs and help them function normally — in people with other forms of idiopathic pulmonary fibrosis.
