NCT07356310

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,

Outcome Measures

Primary Outcomes (1)

  • Oscillometer

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

    Single measurement, approximately day 1

Study Arms (1)

Subjects with dyspnea referred for methacholine challenge testing

Subjects with dyspnea being evaluated for asthma who are referred for methacholine challenge testing

Device: Oscillometer

Interventions

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

Subjects with dyspnea referred for methacholine challenge testing
