What happens to the baby’s lungs during delivery what happens to them after delivery?

After delivery, as a baby breathes for the first time, the lungs fill with air and more fluid is pushed out. Any remaining fluid is then coughed out or slowly absorbed through the bloodstream and lymphatic system. Babies with TTN have extra fluid in their lungs or the fluid leaves too slowly.

Where does the fluid in baby’s lungs go after birth?

More fluid gets reabsorbed as they pass through the birth canal during delivery. The rest of the fluid is absorbed into the lungs after they are born and start breathing on their own. If the fluid isn’t absorbed fast enough or if they have too much fluid in the lungs, they can’t take in oxygen very well.
