Generally, candidates who should be evaluated for Zephyr Valve Treatment are patients who:

1. • Have a confirmed diagnosis of COPD or emphysema
   • Have to stop to catch their breath often, even with taking their medication as directed
   • Have reduced lung function (FEV1≤50% predicted)

These are general criteria but only a Zephyr Valve trained physician can determine if you are a candidate. There is an evaluation process to determine if you are a candidate for the treatment. Find a treating center near you.

A simple set of tests are required to determine if you might be a good candidate for the treatment. These include pulmonary function testing (PFTs), a CT scan, ABG (a blood test), and a 6-minute walk test. Additional tests may include an echocardiogram and a perfusion scan.

Yes, you will need to quit smoking at least 4 months prior to receiving the Zephyr Valve Treatment and must refrain from smoking after the procedure. 

The procedure is for adult patients (18 years and older). A Zephyr Valve trained physician will determine if you are a candidate but there is no strict upper age limit.

Patients should not have this treatment if they do not meet certain criteria.  You will need to go through a number of tests to see if you qualify.  Some of the most common reasons why patients do not qualify are:

• Unable to have a bronchoscopic procedure.
• Have an active lung infection.
• Have an allergy to nitinol, nickel, titanium, or silicone.
• Have not stopped smoking.
• Have an air pocket (bullae) that is greater than 1/3 of the size of the lung.
• Have passages or channels in their lungs that bypass the normal airways (collateral ventilation).
• Primary symptoms are a result of another non-COPD/emphysema health condition.
