Area under the inspiratory flow-volume curve (AIN): Proposed normative values
Octavian C. Ioachimescu,

Abstract:Rationale
Area under expiratory flow-volume curve (AEX) has been shown to be a valuable functional measurement in respiratory physiology. Area under inspiratory flow-volume loop (AIN) also shows promise in characterizing upper and/or lower airflow obstruction.
Objectives
we aimed here to develop normative reference values for AIN, able to ascertain deviations from normal.
Methods
We analyzed AIN in 4,980 spirometry tests recorded in non-smoking, healthy individuals in the Pulmonary Function Testing Laborat… Show more
