Specifically, the baby may not yet have enough alveoli, which are the tiny air sacs that allow for gas exchange within the lungs, to oxygenate their blood properly. A lack of alveoli makes breathing very difficult and highly inefficient. </p><h2>How the immature lung is diagnosed</h2><p>Depending on how prematurely a baby is born, breathing problems may be due to an immature lung rather than a specific disease or complication of the lung. Because a baby’s lungs mature in the later stages of pregnancy, babies born extremely or moderately premature may have immature lungs that lead to breathing problems. </p><p>If an immature lung is suspected to be the cause of a premature baby’s breathing problems, a diagnosis is determined by ruling out other possibilities. This is called diagnosis by exclusion and it is done because the symptoms of an immature lung can be very similar to other lung conditions and complications. </p><p>X-rays will be taken, though often with an immature lung, while the volume of the lung may appear small, the inner surface of the lung will appear normal. Babies with immature lungs will often show the following signs:</p><ul><li>tachypnea, or rapid breathing, which may indicate that the baby is working harder to eliminate carbon dioxide from the blood by increasing the frequency of breaths. Carbon dioxide is tthey werete product of breathing.</li><li>indrawing, or powerful sucking in of the chest with each breath, exposing the ribs beneath the skin. Indrawing often looks as if the chest wall is collapsing inward with each respiration and can be mild to severe. </li><li>cyanosis, or a bluish tinge to the skin, which is a sign of a low amount of oxygen in the blood </li></ul><p>Blood gases will be tested and blood cultures will be done to check for infection.</p><p>The baby will be given surfactant replacement therapy, though because the problems go beyond a lack of surfactant, the therapy will often not improve breathing to any large degree. If no definitive diagnosis has yet been made, and the baby does not respond positively to surfactant therapy, it may be a sign of an immature lung. </p><p>More information</p><ul><li> <a href="/Article?contentid=1763&language=English">The immature lung</a> </li><li> <a href="/Article?contentid=1835&language=English">Treatment of the immature lung</a> </li></ul>Diagnosis of the immature lung in premature babies
