Premature infants may develop respiratory distress and can land up in respiratory failure sometimes needing an intensive care for such infants. This may be due to:
(1) the sudden change from the uterine environment to the air
(2) the incomplete development of the lung surface
(3) inadequate production of surfactant
(4) mutations in the genes involved in lung formation
