Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Nasopharyngeal suction will be performed by physiotherapist with working experience more than 1 years. Besides, surgical mask \& enclosure tent will be adopted as the enclosure barrier device in this study.
Research Question
1. To assess the extent of the environmental contamination during coughing and simulated airway suction
2. To measure the air particle count during coughing and simulated open airway suction.
3. To evaluate how effective the enclosure barrier in reducing the air particle dispersion during open airway suction.
