What is respiratory failure?

Respiratory failure happens when a person's lungs can't get enough oxygen to the blood. This is a severe problem that may need to be treated in intensive care.

Many organs such as the eyes, the brain, and the heart depend on a steady supply of oxygen they get from the blood. The doctor will try to get enough oxygen to those organs to keep them healthy.

Many things can cause lung failure. They include pneumonia and other serious infections. The doctor will look for the cause of the problem and then treat it if possible.

How is it treated?

To help your child's lungs get enough oxygen, the doctor may use a few devices. These vary in how much oxygen they give and how they help your child breathe. They are:

• A special face mask that delivers more oxygen. There are different kinds. A face mask with a bag on one end is called a non-rebreather mask.
• Special oxygen prongs called high-flow nasal cannula. It can warm and wet the oxygen it delivers, so getting high amounts of oxygen feels better to your child.
• A face mask that gives your child oxygen through a machine that changes the air pressure. This may help your child to breathe in and out. The machine may deliver CPAP (continuous positive airway pressure) or BiPAP (bilevel positive airway pressure).
• A ventilator that helps your child breathe or that breathes for them. It controls how much air and oxygen flow into the lungs. This machine requires a breathing tube in the windpipe. It can be uncomfortable, so your child may get medicine to help them relax or sleep. They also will get fluid through an intravenous (IV) tube.

Your child will get regular tests to see how much oxygen is in their blood. Tests also can show how well their lungs are working. These tests help the doctor adjust the machines and oxygen supply.

The doctor will watch your child closely.
