How many alveoli are present in lungs? Insufficient surfactant in the alveoli is one of the causes that can contribute to atelectasis (collapse of part or all of the lung). Without pulmonary surfactant, atelectasis is a certainty. The severe condition of acute respiratory distress syndrome (ARDS) is caused by a deficiency or dysfunction of surfactant. Insufficient surfactant in the lungs of preterm infants causes infant respiratory distress syndrome (IRDS). The lecithin–sphingomyelin ratio is a measure of fetal amniotic fluid to i…
