How to do pursed lip breathing:
1. Breath in (inhale) slowly through your nose for 2 counts.
2. Feel your belly get larger as you breathe in.
3. Pucker your lips, as if you were going to whistle or blow out a candle.
4. Breathe out (exhale) slowly through your lips for 4 or more counts.
Exhale normally. Do not force air out. Do not hold your breath when you are doing pursed lip breathing. Repeat these steps until your breathing slows.
