Impact of breath-detection algorithms on main MBW outcomes.

Relative difference (Spiroware–custom; mild (10%)) in main MBW outcomes (LCI, FRC, CEV) by age group (infants (0 to 2 years), pre-school age (>2 to 6 years), school age (>6 to 11 years), adolescents (>12 years)). Abbreviations: LCI2.5%: lung clearance index; FRC: functional residual capacity; CEV: cumulative expired volume.以Spiroware定制版方案（轻度偏差阈值为10%）计算的主要多次呼吸冲洗试验（Multiple Breath Washout，MBW）结局指标（肺清除指数（lung clearance index, LCI）、功能残气量（functional residual capacity, FRC）、累积呼出容积（cumulative expired volume, CEV））的相对差异，按年龄段（婴儿期：0~2岁、学龄前：>2~6岁、学龄期：>6~11岁、青少年期：>12岁）分组。缩写说明：LCI2.5%指肺清除指数（lung clearance index）；FRC指功能残气量（functional residual capacity）；CEV指累积呼出容积（cumulative expired volume）。
