Pursed-lip breathing
The American Lung Association describes pursed-lip breathing as inhaling through the nose and exhaling slowly through pursed lips. The technique is often used to slow breathing and can be taught in pulmonary rehabilitation settings.
Diaphragmatic breathing
Diaphragmatic or belly breathing focuses attention on movement of the diaphragm and abdomen. Some people find it easier to learn with instruction from a respiratory or rehabilitation professional.
Practice when stable
Techniques are usually easier to learn when a person is not in acute distress. If you have a diagnosed respiratory condition, ask your clinician or therapist how a technique fits your treatment plan.
Know the limits
Breathing exercises should never delay emergency care for sudden severe breathlessness, blue lips or face, chest pain, confusion or other alarming symptoms.
