Persistent coughing can cause fatigue, particularly if it is not effective coughing. This technique helps patients to cough better and reduce fatigue.
The technique is best performed sitting down with a straight back and feet on the floor. The patient starts by taking several gentle but deep breaths. Then, placing one hand on their stomach, they can breathe in as normal while tightening the muscles in their chest and stomach and then exhale strongly with an open mouth while saying the word “huff.”
