Pursed-lips breathing helps keep the airways open for longer, allowing more air to flow into and out of the lungs, thus increasing the chance for oxygen and carbon dioxide exchange, which lengthens the amount of time they can exercise. It also makes breathing easier in general, allowing the person to focus, slow their breathing, and stay calm.
The experts at the COPD Foundation recommend these four steps to practice pursed-lips breathing:
1.Breathe in through the nose (as if smelling something) for about two seconds.
2.Pucker the lips as if getting ready to blow out candles on a birthday cake.
3.Breathe out very slowly through pursed lips, two to three times longer than you breathed in.
4.Repeat.
