- n. A surface-active substance.
- n. A substance composed of lipoprotein that is secreted by the alveolar cells of the lung and serves to maintain the stability of pulmonary tissue by reducing the surface tension of fluids that coat the lung.
- n. chemistry A surface active agent, or wetting agent, capable of reducing the surface tension of a liquid; typically organic compounds having a hydrophilic "head" and a hydrophobic "tail".
- n. biochemistry A lipoprotein in the tissues of the lung that reduces surface tension and permits more efficient gas transport.

“A "surfactant," technically, is a type of wetting agent that lowers surface tension between liquids - but we recognize surfactants more commonly in such products as dishwashing detergent or shampoo.”
“In addition, Midwifes are not able to intervene correctly in Emergency situations, and can only provide improvised care until an EMS unit arrives - no cardiac monitor, no ventilator, no ability to place advanced lines and do advanced IV therapy and advanced medications such as surfactant on the neonate and it's impossible outside of an isolette to provide a thermoregulatory environment for a critically ill neonate, and conditions such as gastroschesis, oomphalacele, diaphragmatic hernia, CHD, and others can be undetected until the baby is born.”
