| Research Abstract |
Pneumonia due to a silent aspiration occurred very often in the elderly patients, and its prevention has become an urgent and challenging issue. We developed an objective and convenient measurement system to assess cough reflex, phlegm expulsion, and swallowing muscle activity, which functioned as defending mechanisms of silent aspiration. In addition, we examined our system in terms of its usefulness. The system constitutes 1) a real-time integrated EMG meter to record swallowing muscle activities, 2) an IC recorder with throat microphone to record choking and swallowing sounds and audio occurred in cough reflex, 3) an analysis software which enables to analyze long-time EMG and sound data. By establishing our assessment method, we are able to take measures against an aspiration pneumonia caused by silent aspiration.
