What is the primary goal of pursed-lip breathing?

The primary goal of pursed-lip breathing is to enhance exhalation. This technique involves inhaling through the nose and exhaling slowly through pursed lips, resembling a whistle or blowing out a candle. By creating a resistance during exhalation, this method helps to keep the airways open longer, which prevents the premature collapse of alveoli.

When the airways remain open longer, it allows for better gas exchange and helps to eliminate carbon dioxide more effectively. As a result, this technique is particularly beneficial for individuals with respiratory conditions like COPD, as it can improve ventilation and relieve shortness of breath. The proper management of exhalation through pursed-lip breathing can significantly increase the efficiency of the respiratory system, allowing patients to breathe more comfortably.
