What does altered respiratory state in RDS result from?

The altered respiratory state in Respiratory Distress Syndrome (RDS) primarily results from surfactant deficiency in the lungs. Surfactant is a substance produced by the epithelial cells of the alveoli that reduces surface tension, preventing the alveoli from collapsing and allowing for proper gas exchange during respiration. In conditions such as neonatal RDS, which most commonly affects premature infants, there is insufficient surfactant production due to the immaturity of the lungs. This deficiency leads to increased surface tension in the alveoli, making it difficult for the lungs to expand and resulting in atelectasis (collapse of the alveoli). Consequently, this impairs oxygenation and contributes to the clinical presentation of respiratory distress in affected infants.

While factors like amniotic fluid levels, surfactant overproduction, and the speed of labor may influence the overall health of an infant, they do not directly cause the altered respiratory state linked to RDS. The primary issue in RDS relates specifically to insufficient surfactant, making it the key factor in the development of the syndrome.
