A patient with complete spinal cord injury at C4-C5 demonstrates a weak cough. Which technique would MOST effectively augment coughing?

• A. Manual pushing against the upper abdomen
• B. Positioning the patient in prone
• C. Pursed-lip breathing
• D. Interrupting the expiratory air stream

Answer: (A)

When someone has a high cervical spinal cord injury, the ability to generate a strong cough is limited because the muscles used to force air out of the lungs are weak. The most effective way to boost coughing is to provide manual assistance that increases expiratory force. Applying quick, firm pressure to the upper abdomen during the exhalation phase raises intra-abdominal pressure, which pushes the diaphragm upward and adds a powerful expulsive push to the air leaving the lungs. This cooperative action between the therapist and the patient produces a higher peak expiratory flow, making it much easier to clear airway secretions. Other approaches don’t deliver that same mechanical boost. Positioning in prone isn’t reliably effective for enhancing cough force. Pursed-lip breathing can help with general airway control but doesn’t generate the strong expiratory thrust needed for an effective cough. Interrupting the expiratory air stream would hinder, not help, coughing.
