Interventional
Description of intervention(s) / exposure
A small nasal airflow oscillation device that plugs into the nose to create nasal pressure oscillations at 130 Hz has been developed. The purpose of this study is to assess the acceptability, safety, and possible efficacy of this small nasal airflow oscillation device in subjects suffering nasal congestion. The subject will be asked to wear the device in their nose on one occasion for 20 minutes. Participants will be asked to sit down quietly for twenty minutes. The participants will be monitored by research staff on a regular basis.
