The screening process, which is now offered in 47 states, involves checking the amount of oxygen in a baby's blood.
Before, the screenings were only mandatory in eight states including: New York, New Jersey and Connecticut.

CCHD was the cause of six percent of infant deaths. However, the hope is that number will continue to decrease due to the screenings.
