Swallowing Disorders Flashcards
4 phases of swallowing
1) Oral preparatory phase
2) Oral phase
3) Pharyngeal phase
4) Esophageal phase
Oral preparatory phase
Begins when food or liquid is consumed through diet and enters the oral cavity
When drinking liquids, the posterior tongue rises to meet the soft palate to ensure a proper seal, preventing leakage of liquid oral cavity contents
Processing of the bolus to render it “swallowable”
Oral phase
Refers to the propelling of food from the oral cavity into the oropharynx
Pharyngeal phase
Rapid sequence of overlapping events
Soft palate elevates, hyoid bone and larynx move upward and forward, vocal folds move to the midline, epiglottis folds backward to protect the airway
Esophageal phase
Tongue pushes backward and downward into the pharynx to propel the bolus down
Assisted by the pharyngeal walls, which move inward with a progressive wave of contraction from top to bottom
Upper esophageal sphincter relaxes during the pharyngeal phase of swallowing and is pulled open by the forward movement of the hyoid bone and larynx
Aspiration
Breathing fluid, food, vomit, or an object into the lungs
Silent aspiration
Aspirating food or fluids without coughing or choking and later developing pneumonia or other conditions
Penetration
Occurs when food or liquids enters the top of the airway
Residue/Stasis
Leftover material in the throat
What causes dysphagia?
Usually caused by another health condition
Conditions that affect the nervous system such as: stroke, head injury, or dementia
Cancer (mouth cancer, esophageal cancer)
Gastroesophageal reflux disease
Does everyone aspirate?
Everyone has the ability to aspirate
Normal to happen from time to time
Does everyone who aspirates get pneumonia?
No
Compensatory strategies for dysphagia
Chin tuck, head tilt, head turn, food hardening/softening
Restorative exercises for dysphagia
Take a deep breath and keep holding your breath as you place a small bite of food in your mouth and swallow
Then, cough to clear any remnants of saliva or food which may have gone down past your vocal cords
Lastly, exhale
Do people with normal swallowing occasionally penetration or aspirate?
Yes
