pursed-lip breathing a breathing technique in which air is inhaled slowly through the nose and then exhaled slowly through pursed lips. This type of breathing is often used by patients with chronic obstructive pulmonary disease to prevent small airway collapse.
Breathing is the process by which oxygen in the air is brought into the lungs and into close contact with the blood, which absorbs it and carries it to all parts of the body.
