Participant Flow

Neonates were enrolled between January and August, 2005. This was an open-label study with 2 treatment groups (Regimen 1 and Regimen 2). Eligible neonates were sequentially enrolled and stratified by GA into 2 strata for each regimen. For each regimen, enrollment in Stratum 1 (30 to 32 GA) was completed before enrollment in Stratum 2 (28 to 29 GA).

a/A ratio is a relative way to judge the lungs ability to transport O₂. It compares the partial pressure of O₂in the alveoli (A) to the partial pressure of O₂in the artery (a). It is calculated by dividing the partial pressure of O₂in the artery, abbreviated PaO2, by the partial pressure of O₂in the alveoli using the alveolar gas equation, abbreviated PAO2. A value of 0.80 or above is normal, a value of 0.60 or below may be incompatible with spontaneous breathing, and a value below 0.22 indicates severe lung disease.
