Huff cough

What is huffing?

Huffing is similar to coughing and a way to clear the lungs of mucus. Instead of a forceful cough, 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 into the larger airways of the lung, making the cough more effective. You may be instructed to perform huff cough along with other airway clearance methods.

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.
• With your mouth open, breathe out steadily, exhaling as much air as you can.
• 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?
