Brief Summary:
The purpose of this study is to examine if infants are more likely to suffer from respiratory complications during their first year of life due to being born premature.

Condition or disease Intervention/treatment
Premature Lungs Other: Diffusion Capacity of the Lung for Carbon Monoxide (DLCO)

Detailed Description:
The overall objective of this study is to determine if infant respiratory morbidities after preterm birth are highly variable due to differential impairment of airway, parenchymal and vascular development that can be characterized as distinct physiologic phenotypes. If the nature and severity of these specific impairments of lung function are strongly associated with increased respiratory morbidities during infancy and that proteomic biomarkers can enhance the physiologic characterization of phenotype and prediction of late respiratory outcomes.

 Other: Diffusion Capacity of the Lung for Carbon Monoxide (DLCO)
Infant lung function testing


Outcome Measures

Primary Outcome Measures :
  1. Infant lung development measured by diffusion lung capacity (DLCO). [ Time Frame: By 5 months CGA. ]
    To characterize respiratory phenotypes through specific physiologic measures that quantify and identify predominant small airways, parenchymal and vascular dysfunction at 4 months CA and determine whether these phenotypes define risks for late respiratory morbidity during infancy.
