Evaluating the Use of a Device Called Impulse Oscillometry in Participants With Vocal Cord Disorders or Asthma

The Study of Impulse Oscillometry in Inducible Laryngeal Obstruction

NCT05246930•University of Rochester

Summary

This study will determine if airway resistance to airflow and pressure, measured by Impulse Oscillometry, is impacted in subjects with vocal cord disorders and whether these measurements are different when compared to subjects with asthma.
