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

University of Rochester43 enrolled

Overview

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.

Study Type

OBSERVATIONAL
