is the passage of swallowed material below the vocal cords without coughing.
However, some episodes of aspiration do not bring about perceptible changes during clinical evaluation, which is called silent aspiration
The PAS score of our patient was 8, which means silent aspiration
(aspiration without cough reflex).
Thus, a score of 8 indicates the most severe condition: aspiration of material without a reflexive or conscious attempt to expel it, which is referred to clinically as silent aspiration
Absence of a cough response to stimulation with silent aspiration
is atussia; both conditions represent breakdown within airway defense mechanisms (Bolser, Gestreau, Morris, Davenport, & Pitts, 2013).
Silent aspirators could cause study results to appear more favorable because approximately 30%-40% of patients with stroke present with silent aspiration
, which is not identifiable on bedside screening (Courtney & Flier, 2009).
There also might have been children with silent aspiration
that was not recognized.
When subclinical events of gastric aspiration occur, it is described as "silent aspiration
" or "microaspiration."
This is known as silent aspiration
. Silent aspiration
may be suspected in individuals with a history of frequent respiratory problems, even without other signs of a cold (like nasal congestion or runny nose).
In particular, oral-motor therapists look for and work on oral defensiveness, texture sensitivity, jaw weakness, swallowing dysfunction, silent aspiration
, weak suck, and bottle dependence.
may then occur and the only sign of oropharyngeal dysphagia is then bronchopneumonia.
Two stroke subjects (S1 and S3) each had an average P-A Scale score of 8, indicating silent aspiration
. They also demonstrated dysphagia in other swallowing domains.
