Related to mucociliary clearance: mucociliary clearance rate

mucociliary clearance

the movement of the mucous covering of the respiratory epithelium by the beating of cilia: rapid, forward (effective) stroke and slow, return (recovery) stroke. In the nose, mucus is moved toward the pharynx. In the tracheobronchial tree, mucus is moved toward and through the larynx and swallowed.

The movement of the mucous covering of the respiratory epithelium by the beating of cilia: rapid, forward (effective) stroke and slow, return (recovery) stroke.

Besides facilitating bacterial adherence to epithelial cells, cigarette smoke decreases mucociliary clearance by the respiratory epithelium and induces inflammation that may cause epithelial injury, predisposing to colonization, he said (Clin.
Medical treatment of mucociliary clearance by pharmacological increase of CBF could be a basic therapeutic approach by eliminating the congestion of mucus secretion.
Second, pulmonary mucociliary clearance mechanisms are minimal in the alveolar region of the lungs.
As the patient's condition deteriorated progressively and he had difficulty in expectorating sputum, salbutamol, 0.5 g four times a day, driven by a jet nebulizer at 6 L of oxygen per ruin, was given to assist mucociliary clearance. His oxygen saturation remained normal without supplemental oxygen.
Normal airway clearance is accomplished by two major mechanisms: the mucociliary clearance system (MCS) and the ability to cough.
Airway clearance problems may be due to problems with loss of cough reflex, slowing of mucociliary clearance, and alterations in airway mediation, all due to the denervation.
Mechanical disruption of ciliated airways (eg, bronchoscopic examination, endotracheal intubation or prolonged coughing) causes mucociliary dysfunction.[32] Opiates, benzodiazepines and general anesthetics inhibit mucociliary clearance of the airways.[3]
