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 describes the process of inhaling and exhaling air. The exchange of gases (oxygen and carbon dioxide) between living cells and the environment is a process known as respiration. The respiratory system, which controls breathing and respiration, consists of the respiratory tract and the lungs.
