Q

Why do individuals with paradoxical vocal fold motion often end up in the ER? How does this contribute to misdiagnosis?

A

Because symptoms mirror asthma attack or laryngospasm, often creating panic reaction
Patients go to ER and treated symptomatically before diagnosis is made
Patients dont respond to standard asthma therapy & end up testing negatively for asthma symptoms
