The lungs are some of the last organs to develop in your baby’s body during the prenatal stage. Some important parts of their lungs don’t develop until the end of pregnancy. Surfactant is a substance that helps reduce surface tension in their lungs. It doesn’t develop until the eighth or ninth month of pregnancy. If your baby is born prematurely, their lungs may not have time to develop fully. This can lead to a variety of breathing disorders.
If your baby has a breathing disorder, they may develop symptoms immediately after they’re born or days later. The symptoms can include:
Prematurity is the main cause of breathing disorders related to lung development. If your baby’s lungs aren’t fully developed by the time they’re born, they may have problems breathing. Congenital defects that affect their lung or airway development can also lead to breathing problems.
Many types of of breathing disorders related to lung development exist. They usually occur when a baby is born before their lungs have time to develop completely. The following types of breathing disorders can occur:
Apnea occurs when your baby stops breathing temporarily for 20 seconds. It can also happen if they stop breathing for less than 20 seconds and it occurs with bradycardia, or a slow pulse, and cyanosis, or bluish discoloration of the skin. It can occur if your baby is born prematurely and their neurological system is still immature. Their nervous system controls their breathing.
If your baby is born prematurely, and their lungs aren’t fully developed, they have an increased risk of getting pneumonia. Meconium is the earliest stool that your infant produces, sometimes in the womb. It’s possible for them to inhale meconium shortly after birth. This is called "aspiration." This can cause an infection in their lungs or lung inflammation. Pneumonia can occur due to an infection or meconium aspiration.
If your baby was born prematurely, their surfactant might not be fully developed. This can cause their lungs to collapse, making it difficult for them to breath. This condition is called respiratory distress syndrome. It’s most common in newborns, especially those born six weeks prematurely or more.
Babies born more than 10 weeks early are at the greatest risk of bronchopulmonary dysplasia. This condition can occur due to therapy your baby may receive if they have premature lung development. If your baby is born this early, they may need to receive oxygen and breathing help from a mechanical ventilator. This treatment is lifesaving. However, it can also scar your baby’s fragile lungs. This can make it even harder for them to breathe.
Your baby is at higher risk of breathing disorders if they’re born before their lungs have time to mature fully. The earlier your baby is born, the greater their risk of breathing problems.
Your baby’s doctor may diagnose them with a breathing disorder, based on observable signs and symptoms. Several diagnostic tests can also help them learn if your baby has a breathing disorder. For example, they may order:
Your baby’s treatment plan will depend on their specific condition and the severity of their symptoms. Their doctor may prescribe medications, oxygen therapy, or mechanical ventilation.
Medications for infant breathing disorders include the following:
Breathing problems may stop your baby from getting enough oxygen into their lungs. They may need oxygen therapy.
If your baby can’t breathe on their own due to lung problems, they may need help from a machine known as a ventilator.
If your baby’s breathing problems are due to a congenital defect, they may need surgery to correct the problem. Your baby’s doctor may also recommend home care, which may involve continued oxygen administration and respiratory therapy.
Your baby’s outlook will depend on several factors, such as:
If your baby’s doctor diagnoses them with a breathing problem, ask them for more information about their specific condition, treatment options, and outlook.
It’s not always possible to prevent your baby from developing breathing disorders. Avoiding premature delivery will lower their risk of developing breathing problems. If you’re pregnant, you can reduce your risk of premature delivery by following these tips for a healthy pregnancy:
