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 (or respiration, or ventilation) is the process of moving air into and out of the lungs to facilitate gas exchange with the internal environment, mostly by bringing in oxygen and flushing out carbon dioxide.
