Mucus build-up can also cause infection, and inflammation, and repeated infections can result in damage to the airways, and the lung tissue. [1] [2] All airway clearance therapy involves the techniques of coughing, or huffing that need to be used in conjunction with another airway clearance technique. [3] Respiratory therapists make ...
Chest congestion is usually caused by excess mucus in the airways, says Meilan King Han, M.D., M.S., professor of medicine and chief of the Division of Pulmonary and Critical Care at the ...
Mucoactive agents are a class of chemical agents that aid in the clearance of mucus or sputum from the upper and lower airways, including the lungs, bronchi, and trachea. Mucoactive drugs include expectorants, mucolytics, mucoregulators, and mucokinetics.
If secretions are cleared from larger airways, airway resistance and obstruction should decrease. Clearance of secretions and improved ventilation of small airways should increase lung compliance. If clearance of secretions from both large and small airways occurs, it is reasonable to assume that the work of breathing and oxygen consumption ...
Chest wall oscillation is when devices are used in airway clearance therapy to clear excess mucus from lung airways (bronchi and bronchioles).It is principally used in the treatment of cystic fibrosis, but is gaining use in the treatment of other diseases, such as bronchiectasis, COPD, cerebral palsy and muscular dystrophy, in which excessive mucus can block airways due to excessive production ...
The mechanism of disease is breakdown of the airways due to an excessive inflammatory response. [3] Involved airways become enlarged and thus less able to clear secretions. [3] These secretions increase the amount of bacteria in the lungs, resulting in airway blockage and further breakdown of the airways. [3]
