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.
