Pursed Lip Breathing
Pursed lip breathing is a technique designed to slow down exhalation, keep airways open longer, and improve the efficiency of gas exchange. It helps to reduce the work of breathing and alleviate shortness of breath, particularly in individuals with obstructive lung diseases.
- 1Relax your neck and shoulder muscles.
- 2Inhale slowly through your nose for two counts, keeping your mouth closed.
- 3Pucker or "purse" your lips as if you are about to whistle or gently blow out a candle.
- 4Exhale slowly and gently through your pursed lips for at least four counts, making the exhalation at least twice as long as the inhalation.
- 5Repeat this pattern, focusing on a slow, controlled exhalation.
Pursed-lip breathing (PLB) creates positive end-expiratory pressure (PEEP) in the airways by increasing resistance during exhalation. This back-pressure helps to keep small airways open, preventing their premature collapse, which is common in obstructive lung diseases like COPD. By slowing down the expiratory flow, PLB allows more time for gas exchange, reduces air trapping in the lungs, and decreases the work of breathing. This improved ventilatory efficiency can lead to a reduction in dynamic hyperinflation, lower respiratory rate, and a decrease in the sensation of dyspnea, thereby reducing sympathetic nervous system activation and promoting a sense of calm.
