A Simple Heart Test for Newborns
One in 100 newborns has a malformed heart. It's the most common birth defect. Now, a federal advisory panel recommends a simple and painless test for all newborns to detect such defects before the babies are released from the hospital.
Pulse oximetry measures the amount of oxygen in the blood via a small light sensor taped to a baby's wrist, hand or foot. It's inexpensive ($5-$10), fast (five minutes) and can detect a life-threatening condition otherwise difficult to find in a physical exam. An infant's cardiovascular system might appear normal in the first few days after birth, even though it continues to mature.
According to WebMD, only two states -- Maryland and New Jersey -- legally mandate the test. Some hospitals elsewhere do it voluntarily, but it's not in widespread use.
The federal panel's advice has been endorsed by the American College of Cardiology, the American Heart Association and the American Academy of Pediatrics.
If you're expecting, and you don't live in Maryland or New Jersey, make sure your hospital knows you want the test to be performed before your bring junior home. The chances of heart problems are low, but it's better know if there is one -- and to address it -- before it presents far from where it can be treated.
