Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

In a prospective, observational study the investigators compared resistance values measured using the airway perturbation device (APD) to impulse oscillometry and spirometry. The investigators also created reference equations for normal APD resistance ranges using the data from clinically normal volunteers.
