Which symptom is typically present in patients with COPD during respiration?

Patients with Chronic Obstructive Pulmonary Disease (COPD) often exhibit pursed-lip breathing as a common respiratory symptom. This technique involves inhaling through the nose and exhaling slowly through pursed lips, which helps to maintain airway pressure, prevent air trapping, and improve ventilation. The act of prolonging exhalation can help them expel trapped air in the lungs and facilitate better oxygen exchange.

Pursed-lip breathing is particularly beneficial for COPD patients as it aids in controlling the respiratory rate and decreasing the work of breathing. This method can also help manage feelings of breathlessness that are frequently experienced in COPD. By implementing this technique, patients can take fuller breaths and enhance their overall breathing efficiency, which is critical given the chronic airflow limitation associated with the disease.

Other symptoms like a regular breathing pattern, deep sighs, or a slow respiratory rate may not be characteristic of COPD. Patients typically present with an irregular and sometimes rapid respiratory pattern, especially during exacerbations, instead of a regular one.
