Endobronchial valve therapy is a treatment option for severe chronic obstructive pulmonary disease (COPD). Endobronchial valves are one-way valves placed in the lungs. The valves help to reduce rapid breathing (hyperventilation) and allow air trapped in the lungs to come out. This helps the healthier parts of your lungs work better. This therapy can improve lung function and quality of life.

This procedure is done in a hospital. You will get medicine to relieve pain and help you sleep. Some people find that they don't remember having the procedure because of the medicine.

The doctor gently moves a small tube, or bronchoscope, through the nose or mouth and down to the lungs. The scope is also a small video camera. It lets the doctor see the lungs. This helps the doctor place endobronchial valves where they're needed in the lungs.

The procedure usually takes 30 to 60 minutes.

Risk factors for this procedure may include your past health and the severity of COPD.

Risks may include:

• A collapsed lung.
• Infection.
• Bleeding.
• Pain.

You may stay in the hospital for a few nights.

You should be back to your usual routine after 2 to 3 weeks. You may notice less shortness of breath.
