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.
Mouth breathing refers to the state of inhaling and exhaling through the mouth. A healthy individual normally breathes through the nose while resting or doing light exercise, and breathes simultaneously through both the nose and mouth during vigorous aerobic exercise, in order to supply sufficient oxygen.
