Content: A routine physical examination, as performed during the first 24 hours of life in most institutions, is only 50 percent effective in detecting CHD. The pulse-oximetry test can help identify infants with low levels of oxygen in their blood and may help diagnose critical CHD before an infant becomes sick. The test has been recommended as a screening test for critical CHD by the: U.S. Department of Health and Human Services
American Heart Association
American Academy of Pediatrics
American College of Cardiology
It is important to note, however, that it is possible for a baby with CHD to have a normal pulse-oximetry reading. CHD cannot be completely ruled out by a normal pulse-oximetry reading. Who Should Be Screened? All infants should be screened. When Should Screening Be Performed? Pulse-oximetry screening should be performed after the infant turns 24 hours of age and before discharge from the nursery. If the infant was born prematurely, screening should be performed when medically appropriate to do so.
