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

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.

Treatment and study plan

Impulse Oscillometer

Device

The tremoFlo C-100 Airwave Oscillometry System is intended to measure respiratory system impedance using the Forced Oscillation Technique (FOT).

Other names: THORASYS tremoFlo C-100 Airwave Oscillometry System

Primary outcomes

Mean respiratory system impedance

Time frame: Single measurement, approximately day 1

The oscillometer will collect an airway impedance measurement which is made up of multiple variables.
