Discuss the importance of surfactant to the preterm infant's lungs.

-Deficient surfactant production causes unequal inflation of alveoli on inspiration and the collapse of alveoli on end expiration. -Infants are unable to keep their lungs inflated and therefore exert a great deal of effort to reexpand the alveoli with each breath.

A primary objective in the care of high-risk infants is to maintain respiration. Describe how the nurse should complete the respiratory assessment.

-Describe shape of chest (barrel/concave), symmetry, presence of incisions, chest tubes or other deviation. -Describe use of accessory muscles: nasal flaring or substernal, intercoastal or subclavicular retractions. -determine respiratory rate and regularity -auscultate and describe breath sounds: Stridor, crackles, wheezing, diminished sounds, areas of absence of sound, grunting, diminished air entry, equality of breath sounds -Determine whether suctioning is needed. -describe ambient oxygen and method of delivery; if intubated, describe size of tube, type of ventilator and settings, and method of securing tube. -determine oxygen saturation by pulse oximetry
