Thoracoabdominal asynchrony: Two methods in healthy, COPD, and interstitial lung disease patients
Fig 6
Bland-Altman graph representing the agreement between OEP and RIP.
OEP: optoelectronic plethysmography, RIP: respiratory inductive plethysmography, ILD: interstitial lung disease, COPD: chronic obstructive pulmonary disease, L50 and L75: 50% and 75% of maximal load. Solid line: mean difference between the 2 methods, Dotted lines: upper and lower limit of agreement (mean ± 1.96 SD).
