Patient Selection

  • Does your patient frequently stop to catch their breath or go slowly while climbing stairs or doing other activities?
  • Does your patient have a Forced Expiratory Volume (FEV1) of 50% of predicted or less?
  • Has your patient been referred for a pulmonary function test and had abnormally high residual volume or total lung capacity?
  • Has your patient been referred for a lung CT scan and had findings of emphysema on the radiology report?

More than 3 in 4 patients would select a treatment with the clinical benefits and risk profile of the Zephyr Valve over current treatment.8

In a patient preference study, a detailed survey of 294 severe emphysema patients evaluated how they balance potential risks and benefits. The study concluded that patients with severe emphysema value access to an interventional treatment that offers benefits above and beyond their current medical management, despite the risks associated with these treatments.

You’re in the best position to identify patients who might benefit from Zephyr Valve treatment.

Key Patient Selection Criteria:

  • Confirmed diagnosis of COPD
  • Non-smoking or willing to quit smoking
  • FEV1≤50% predicted
  • Breathless despite optimal medical management (mMRC≥2)

Making a Referral

Patients who might benefit from Zephyr Valve therapy include:

  • Patients who are not responding to optimal medical management
  • Patients who prefer additional treatment options

Once Referred an Interventional Pulmonologist Will Confirm:

  • Diagnosis of severe emphysema
  • Presence of hyperinflation (RV≥175% predicted)
  • Confirmation the target lobe has little to no collateral ventilation
