The Zephyr Valve is proven to help emphysema patients breathe easier, do more, and enjoy life1

How the Zephyr Valve Works

The Zephyr Valve is the first minimally-invasive bronchoscopic treatment option in the United States for severe emphysema patients

Benefits & Risks

In a clinical study1, patients treated with the Zephyr Valve compared to patients on medication alone were able to:

Breathe easier due to improved lung function

Increase their exercise – they could walk farther

Do more daily life activities, such as walking, bathing, and gardening

Enjoy a better quality of life with more energy

Feel more confident leaving their home


Complications of the Zephyr Endobronchial Valve treatment can include but are not limited to pneumothorax, worsening of COPD symptoms, hemoptysis, pneumonia, dyspnea and, in rare cases, death.
