What is one technique to help a patient with mucus expulsion?

Deep coughing is an effective technique for helping a patient expel mucus from the respiratory system. This method increases airway pressure and creates a strong force that can help dislodge mucus adhering to the airway walls. When performed correctly, deep coughing can enhance the clearance of secretions, making it especially beneficial for patients with conditions like chronic obstructive pulmonary disease (COPD), cystic fibrosis, or any illness involving mucus buildup.

Other breathing techniques, such as shallow breathing, typically do not generate sufficient force to clear mucus effectively and may not facilitate adequate airflow to the peripheral lung areas where mucus can accumulate. Pacing breaths may help with relaxation or managing breathlessness but do not directly target mucus removal. Holding the breath does not promote mucus clearance; instead, it can exacerbate respiratory issues by trapping air and secretions in the lungs. Therefore, deep coughing is undeniably the most appropriate choice for mucus expulsion.
