Asthma, Breathing, Mouth, Laryngeal Obstruction, Lung Function Decreased, Vocal Cord Dysfunction
Conditions
Brief 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.
Interventions
DEVICEImpulse Oscillometer
The tremoFlo C-100 Airwave Oscillometry System is intended to measure respiratory system impedance using the Forced Oscillation Technique (FOT).
