What should be the follow-up protocol if a newborn's CCHD screening results in a percentage between 90-94%?

The follow-up protocol for a newborn's Critical Congenital Heart Disease (CCHD) screening indicating an oxygen saturation percentage between 90-94% typically involves a re-check in one hour. This procedure allows healthcare providers to establish whether the initial reading was accurate or if it was a transient issue. Monitoring the newborn in this way is crucial because a percentage in this range may suggest potential heart abnormalities, and a repeat assessment can provide clarity on the baby's condition.

If the repeat screening shows that the oxygen saturation has improved to above 95%, this would indicate a low likelihood of significant heart disease, allowing for reassurance and continued monitoring. If the results remain low, further evaluation or consultation may be warranted but initially requires this follow-up to determine the appropriate next steps. This approach balances the need for caution with the understanding that some readings may improve without immediate intervention.
