Disadvantage: requires accurate means, qualifications and experience of the doctor to achieve good results. Food cannot be seen as it passes through the pharynx because this organ constricts tightly when swallowing. 4.3. Assessment by capillary oxygen saturation Patients who swallow liquids measure SpO2 with their fingertips. The diagnosis was positive when SpO2 decreased 2% from baseline.
Advantages: non-invasive, easy to do, simple, fast, can be redone many times. Sensitivity 73-87%, specificity 39-87%. Disadvantages: affected by age, low reliability, respiratory pathology. 5. Methods of treating swallowing disorders caused by accidents, brain degeneration 5.1. Compensating technique Positioning technique
