Pursed lip breathing helps control shortness of breath, and provides a quick and easy way to slow your pace of breathing, making each breath more effective and is the rationale the nurse would use when teaching a client with chronic obstructive pulmonary disease (COPD) to use pursed-lip breathing.
Pursed lip breathing works by moving oxygen into your lungs and carbon dioxide out of your lungs. This technique helps to keep airways open longer so that you can remove the air that is trapped in your lungs by slowing down your breathing rate and relieving shortness of breath.
COPD causes the airways to collapse, thus through pursed breathing the pressure helps keep the airways open so that carbon dioxide that's trapped in the lungs can get out.
