Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Subjects with a diagnosis of vocal cord dysfunction
Subjects with a confirmed or suspected diagnosis of vocal cord dysfunction (also called inducible laryngeal obstruction). Some subjects will have concomitant diagnosis of asthma.
Impulse Oscillometer
The tremoFlo C-100 Airwave Oscillometry System is intended to measure respiratory system impedance using the Forced Oscillation Technique (FOT).
Subjects with diagnosis of asthma
Subjects with physician-diagnosed asthma. Some subjects will have concomitant diagnosis of vocal cord dysfunction.
