WheezoMeter® Correlation Study

Prospective Comparative Study of WheezeRATE™ (Wz%) Readings With Spirometry, Symptoms, and Auscultatory Findings in Children With Wheezing.

The primary goal of the study is to more firmly establish correlations between WheezeRate(Wz%) and other parameters used to assess wheezing and asthma including spirometry, provider's auscultation, and symptoms at the time of Wz% measurement.

Inclusion Criteria:

• Patients <= 12 years of age who have wheezing at the time of study as confirmed by the physicians' auscultation.

Control:

• Patients <= 12 years of age without history of asthma or other pulmonary conditions, and who are without wheezing on physical exam.

Exclusion Criteria:

• Medical problems that would contraindicate Wz% measurement.
