Airway clearance therapy is treatment that uses a number of airway clearance techniques to clear the respiratory airways of mucus and other secretions. [1] Several respiratory diseases cause the normal mucociliary clearance mechanism to become impaired resulting in a build-up of mucus which obstructs breathing, and also affects the cough reflex .
When used correctly some help maintain an open airway, like an oropharyngeal airway. Other devices help ventilate the patient so oxygen can be delivered to the lungs and circulated through the body. Oropharyngeal airways of various sizes Oropharyngeal airways (OPA) are curved pieces of plastic that help to maintain a patent airway in ...
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 ...
Mucociliary clearance has a major role in pulmonary hygiene. MCC effectiveness relies on the correct properties of the airway surface liquid produced, both of the periciliary sol layer and the overlying mucus gel layer, and of the number and quality of the cilia present in the lining of the airways. [3] An important factor is the rate of mucin ...
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 ...
Laryngoscopy should be performed in unresponsive patients if non-invasive airway clearance techniques are unsuccessful. [22] Laryngoscopy involves placing a device in the mouth to visualize the back of the airway. [22] If the foreign body can be seen, it can be removed with forceps. [22]
