TTN (Transient Tachypnea of Newborn)

Medically reviewed by Last updated on May 6, 2024.

What is TTN?

TTN is fast and hard breathing that begins within the first hours after birth and then goes away. TTN happens when there is extra fluid in your baby's lungs or the fluid is slow to clear from his or her lungs. Your baby breathes faster and harder as he or she tries to get oxygen into his or her lungs. TTN usually goes away on its own within a few days of treatment in the hospital.

What causes TTN?

Your baby's lungs are filled with fluid while he or she is in the womb. All of your baby's oxygen comes from the blood vessels of the placenta. Fluid begins to clear from your baby's lungs as his or her due date gets close. More of it clears as your baby moves down the birth canal. The rest is cleared when your baby takes his or her first breaths after birth.
