Asthma (Diagnosis), Breathing, Lung Function Decreased, Obesity

Brief summary

This study will determine if airway resistance to airflow and pressure, measured by Oscillometry, is associated with abnormal findings on methacholine challenge testing and whether these findings are associated with body habitus,

Interventions

DEVICEOscillometer

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