Overview

Critical congenital heart disease (CCHD) screening uses a pulse oximeter to measure oxygen saturation, usually on the right hand and a foot. Low oxygen levels can be an early sign of certain serious heart defects. This screening does not detect every heart condition, but it can identify some critical problems early so newborns can receive prompt care.

Who Should Get This Screening

  • Newborns where the program is offered (often before discharge).

What to Expect

A small sensor is placed on the baby’s skin to measure oxygen levels. The test is painless and usually takes a few minutes. If results are abnormal, follow-up assessment (often including echocardiography) is arranged.

How to Prepare

Follow these tips to prepare for your screening

  • No special preparation.

Benefits

  • Early detection of some critical heart defects.
  • Non-invasive, painless, and quick.
  • Enables faster evaluation and treatment when abnormal.

Things to Consider

  • False positives can occur and may lead to additional tests.
  • False negatives are possible (it does not detect all congenital heart defects).
