Diagnostic Workup at Treating Center

The clinical team at the Zephyr Valve treating center will confirm patient eligibility with these tests:

  • Full Pulmonary Function Testing using Body Plethysmography
  • 6 Minute Walk Test
  • High Resolution CT Scan with specialized protocols
  • Echocardiogram
  • Arterial Blood Gas (optional)
