Secondary surfactant deficiency may occur in infants with the following:

Physical findings are consistent with the infant's maturity assessed by using the Dubowitz examination or its modification by Ballard.

Progressive signs of respiratory distress are noted soon after birth and include the following:

  • Tachypnea
  • Expiratory grunting (from partial closure of glottis)
  • Subcostal and intercostal retractions
  • Cyanosis
  • Nasal flaring
  • Extremely immature in neonates may develop apnea and/or hypothermia.
