Information

WHY IS A MECHANICAL VENTILATOR USED?

A ventilator is used to provide breathing support for ill or immature babies. Sick or premature babies are often not able to breathe well enough on their own. They may need help from a ventilator to provide "good air" (oxygen) to the lungs and to remove "bad" exhaled air (carbon dioxide).

HOW IS A MECHANICAL VENTILATOR USED?

A ventilator is a bedside machine. It is attached to a breathing tube that is placed into the windpipe (trachea) of sick or premature babies who need help breathing. Caregivers can adjust the ventilator as needed, depending on the baby's condition, blood gas measurements, and x-rays.

WHAT ARE THE RISKS OF A MECHANICAL VENTILATOR?

Most babies who need ventilator assistance have some lung problems, including immature or diseased lungs, which are at risk for injury. Sometimes, delivering oxygen under pressure can damage the fragile air sacs (alveoli) in the lungs. This can lead to air leaks, which can make it difficult for the ventilator to help the baby breathe.

Long-term damage may also occur because newborn lungs are not yet fully developed. This can lead to chronic lung disease that is called bronchopulmonary dysplasia (BPD). This is why caregivers closely monitor the baby. They will try to "wean" the baby from oxygen or decrease the ventilator settings whenever possible. How much breathing support is given will depend on the baby's needs.
