Abstract:
Purpose In this study, the authors aimed to determine reliability of the airflow perturbation device (APD) to measure respiratory resistance within and across sessions during resting tidal (RTB) and postexercise breathing in healthy athletes, and during RTB across trials within a session in athletes with paradoxical vocal fold motion (PVFM) disorder. Method Prospective, repeated-measures design. The APD measured respiratory resistance during 3 baseline assessments in 24 teenage female athletes, 12 with and 12 without PVFM. Control athletes provided data at rest and following a customized exerc

Abstract:
The airflow perturbation device (APD) has been developed as a portable, easy to use, and rapid-response instrument for noninvasively measuring respiratory resistance in humans. However, the APD has limited data validating it against established techniques; moreover, a method does not exist to standardize resistance measurement outputs between APD units. This study proposes a system that simulates the normal range of human breathing to validate the APD with the clinically accepted impulse oscillometry technique. Two respiratory resistance ranges were tested. The validation system consisted of a
