I was elated when I saw the status on Cora's Story at Facebook that pulse oximetry has been voted YES to be added to the newborn screening.
For many children with a congenital heart defect it can be detected by the use of pulse oximetry. It is a non-evasive test that takes only a minute or two.
It does not detect ALL CHDs but it detects a lot more than would be detected without it. It also can detect the defects sooner than other methods.
