The Pulmonary Education and Research Foundation (PERF) is a 501(c)(3) not-for-profit organization that was formed from a passion to improve the outlook for patients with chronic obstructive pulmonary disease (COPD), through research into pulmonary rehabilitation and other patient-centered therapies. Over time, this purpose has adapted to include other diseases where shortness-of-breath and exercise intolerance are hallmark symptoms.

PERF publishes a free blog, and responds to reader’s questions and concerns, for those who experience breathing difficulties or exercise limitations.
