What is the primary purpose of pursed lip breathing?

1. Increase respiratory rate

2. Enhance oxygen intake

3. Improve lung capacity

4. Promote carbon dioxide elimination

The correct answer is: Promote carbon dioxide elimination

Pursed lip breathing is primarily designed to promote carbon dioxide elimination, which helps regulate the balance of oxygen and carbon dioxide in the body. This technique involves inhaling through the nose and exhaling slowly through pursed lips, creating resistance that helps keep the airways open longer during exhalation. This extended exhalation allows for better removal of carbon dioxide from the lungs, thus enhancing overall respiratory efficiency. While increased respiratory rate and enhanced oxygen intake are beneficial byproducts of this breathing technique, the main focus is on effectively expelling carbon dioxide, which is crucial for individuals with respiratory conditions who struggle with the proper exchange of gases in their lungs. Improving lung capacity can be a potential benefit of practicing pursed lip breathing over time, but it is not the primary purpose of the technique.
