An investigation into the challenges and limitations of implementing universal pulse oximetry screening for critical congenital heart disease in asymptomatic newborns

Abstract

An investigation into the challenges and limitations of implementing universal pulse oximetry screening for critical congenital heart disease in asymptomatic newborns PULSE OXIMETRY SCREENING OF NEWBORNS have CCHD, requiring surgery or catheter intervention, in their first year of life. (9) Most newborns are discharged early if they appear asymptomatic and well. This is often the case with CCHD as the features of their condition are masked during the transition from foetal to "adult" circulation. There are approximately 20% of CHD cases presenting with life threatening illness in the neonatal period, but only a fraction of these newborns are referred for intervention, thus highlighting the importance of timely diagnosis, management and referral for survival. (6,10) Late detection is associated with circulatory collapse, resulting in shock and acidosis with an adverse effect ABSTRACT INTRODUCTION
