Respiratory distress syndrome (RDS) occurs most often in infants who are born too early. RDS can cause breathing difficulty in newborns. If it is not properly treated, RDS can result in complications. This may include pneumonia, respiratory failure, chronic lung problems, and possibly asthma. In severe cases, RDS can lead to convulsions and death.

RDS occurs when infant's lungs have not developed enough. Immature lungs lack a fluid called surfactant. This is a foamy liquid that helps the lungs open wide and take in air. When there is not enough surfactant, the lungs do not open well. This will make it difficult for the infant to breathe.

The chance of developing RDS decreases as the fetus grows. Babies born after 36 weeks rarely develop this condition.
