While conventional spirometry is associated with strenuous "forced" maximal respiratory maneuvers and infection control implications, oscillometry not these issues. However, portability, convenience of use, interpretation remain common limitations to both techniques. This study tested the concordance agreement between resistance measurements obtained from handheld portable REOM device (Reo-f, Reo-s) those (R19, R5) in PFT-confirmed "mild" (GOLD 1) "very severe" 4) COPD. Unadjusted adjusted (Spearman correlation) (Bland-Altman tests) served as co-primary outcomes.
