Cystic Fibrosis: Huff-Cough

What is huffing?

Huffing is similar to coughing. Instead of a forceful cough effect, air is let out steadily while whispering the word "huff," or as if trying to fog up a mirror. This "huff" forces the air and mucus from the small airways in the lung, making the cough more effective.

How do I huff?

  • A huff can be done after taking a large, medium, or small breath.
  • Sit with your back straight and your mouth slightly open.
  • Hold a tissue about two to three inches away from your mouth.
  • Take in a breath and hold for one to two seconds.
  • Breathe out steadily, exhaling as much air as you can with your mouth open.
  • Breathe out forcefully enough to move the tissue.
  • Use stomach muscles to help exhale.
  • Do two or three huff breaths followed by a forceful cough.

NOTE: If a "wheeze" sound is heard, you are breathing out too quickly. Breathe out more slowly.

What is an effective cough?

An effective cough is accomplished by taking a deep breath and holding that breath for one second, followed by a strong and forceful coughing effort.
