The aim of this study was to determine the cardiac and non-cardiac diseases in the Iranian healthy newborns using POX.
In this cross-sectional study we used right hand (pre-ductal) and either foot (post-ductal) POX to evaluate healthy term and near term neonates who were born from October 2017 to March 2018 (6-month period). The oxygen saturation (SPO2) was considered normal if SPO2 was 95% and the difference of pre-ductal O2 saturation and post-ductal POX ≤ 3%. SPO2 was considered abnormal if SPO2 was 0.05). Among them, 3 cases had cardiac disease (Transposition of the great arteries, ventricular septal defect/Pulmonary atresia, ventricular septal defect /Pulmonary hypertension and 3 had non-cardiac disease (Esophageal Stenosis, Hypoglycemia, persistent pulmonary hypertension / Sepsis), and 4 rest were healthy.

Findings showed routine POX screening along with clinical examinations could be applied especially in developing country for
