Testing

Laryngoscopy: Using sounds to mimic VCD episode, a specialist can determine if an athlete has VCD.

All procedures are NON-invasive


CLINICAL EVALUATION

Detailed information is obtained from patient.


SPIROMETRY

Performed by Pulmonary Specialist.  This is the main test doctors generally use to diagnose asthma.  To help determine how well your lungs are working (pulmonary function), you take a deep breath and forcefully breathe out (exhale) into a tube connected to a spirometer. This records both the amount (volume) of air you exhale and how quickly you exhale. If certain measurements are below normal, it may indicate asthma has narrowed your airways.


LARYNGOSCOPY

Performed by a Specialist. This is a medical procedure that is used to obtain a view of the vocal folds and the glottis. Typically, a flexible scope is used to view movement of the vocal cords when a patient is symptomatic. Since VCD is usually not usually present after ceasing exercise, our specialist was able to mimic VCD using sounds created by my daughter while the scope was in place.  


What is Happening? The black areas in the illustration below show the amount of opening to allow for air to pass:
During normal breathing, the vocal cords are apart and optimum amount of air passes through.
During a VCD incident, the vocal cords come together during INHALATION and the opening is significantly reduced resulting in shortness of breath localized to the throat area.

“My lungs are perfectly fine, but I can’t breathe when I push myself in training and competition… I went to the doctor, and he thought it could be asthma, so he prescribed 2 inhalers…” Learn the Difference
