Is your newborn in the NICU at Holtz Children’s Hospital in Miami? Newborns born very prematurely often need oxygen therapy or ventilation to help them breathe and survive. This study will help doctors understand how changes in oxygen and carbon dioxide levels while newborns are getting treatment affect how their lungs develop. While your newborn is in the newborn neonatal intensive care unit (NICU), researchers will record his or her oxygen and carbon dioxide levels, heart rate, and other measures. To participate in this study, your newborn must have been born prematurely between 23 and 28 weeks’ gestation, be less than 28 days old, and be receiving oxygen therapy. This study is located in Miami, Florida.
