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