ABSTRACT
BACKGROUND: Nasal continuous positive airway pressure is frequently used to support preterm infants with respiratory distress syndrome. Little is known about the hemodynamic changes that occur, particularly during the weaning phase when lung compliance has improved and most of the airway pressure can be transmitted to the heart and major blood vessels. METHODS: We conducted a prospective study on preterm infants (gestational age Subject(s)
