Effect of Modified Air-pulse Stimulation on Tracheotomised Patients With Dysphagia After Stroke

Connected the oxygen humidification bottle to a fibreoptic endoscope, then inserted the terminal into the nasal cavity and the pulse sensation stimulation generated by oxygen was transmitted through the internal port of the fibreoptic endoscope to the anterior wall of the pyriform recess or to the folds of the arytenoepiglottis. (5 min once a day for 2 weeks)

The terminal airway of the air pulse was placed in the oral cavity, specifically in the patient's palatoglossal arch, pharyngeal posterior wall, tongue base, and other areas. The airbag was quickly squeezed to generate airflow and stimulate the mucosa.(5 min once a day for 2 weeks)
