Health professionals’ views of newborn pulse oximetry screening in a midwifery-led maternity setting. “It's a good thing to do, but fund it!”

Congenital heart defects in infants are the commonest congenital abnormality but even critical lesions can be difficult to identify clinically in the first days after birth during the period of physiological transition and while the ductus arteriosus remains patent (Wren et al., 2008). Accordingly, clinical assessment of newborns with congenital heart disease (CHD) within the first 24 h often yields normal findings (Abu-Harb et al., 1994; Saxena et al., 2015). Failure to make an early diagnosis of critical CHD leads to clinical compromise prior to infants receiving major surgery and is associated with increased infant mortality (Eckersley et al., 2016; Franklin et al., 2002).
