The airflow perturbation device (APD) has been developed as a portable, easy to use, and a rapid response instrument for measuring respiratory resistance in humans.
However, the APD has limited data validating it against the established techniques.
This study used a mechanical system to simulate the normal range of human breathing to validate the APD with the clinically accepted impulse oscillometry (IOS) technique.
The validation system consisted of a sinusoidal flow generator with ten standardized resistance configurations that were shown to represent a total range of resistances from 0.12 to 0.95 kPa·L−1·s (1.2–9.7 cm H2O·L−1·s).
Impulse oscillometry measurements and APD measurements of the mechanical system were recorded and compared at a constant airflow of 0.15 L·s−1.
Both the IOS and APD measurments were accurate in assessing nominal resistance.
In addition, a strong linear relationship was observed between APD measurements and IOS measurements (R2 = 0.999).
A second series of measurements was made on ten human volunteers with external resistors added in their respiratory flow paths.
Once calibrated with the mechanical system, the APD gave respiratory resistance measurements within 5% of IOS measurements.
Because of their comparability to IOS measurements, APD measurements are shown to be valid representations of respiratory resistance.
