Abstract

OBJECTIVE

To assess concordance in the measurement of peak expiratory flow (PEF) and forced expiratory volume ino ne second (FEV(1)) between the portable device Piko-1 (Ferraris) and a pneumotachograph.

PATIENTS AND METHODS

Forced spirometry (Master Screen Jaeger) was performed according to ATS/ERS norms, selecting the best value of three curves, and three measurements with the Piko-1 were recorded the recommendations of the manufacturer.

RESULTS

Eighty patients between 5-18 years of age were studied. Based on the Bland-Altman method, the mean differences obtained were 9.82 (95%Cl: 2.43-17.21) for PEF and 0.17 (95%CL: 0.12-0.21 for FEV(1). The intraclass correlation coefficient was 0.96 (p <0,001; 95%Cl: 0.93-0.97) for PEV(1) and 0.93 (p<0,0001; 95%Cl: 0.89-0.95) for PEF.

CONCLUSIONS

Piko-1 offers FEV(1) measurements close to those obtained with forced spirometry, thus allowing more exact patient assessment in home-based follow-up emergency services, or hospital wards.

摘要

目的

评估便携式设备Piko-1（法拉利）与呼吸流速仪在测量呼气峰值流速（PEF）和一秒用力呼气容积（FEV₁）方面的一致性。

患者与方法

根据美国胸科学会/欧洲呼吸学会规范进行用力肺活量测定（Master Screen Jaeger），选取三条曲线中的最佳值，并按照制造商的建议使用Piko-1进行三次测量。

结果

研究了80名5至18岁的患者。基于Bland-Altman方法，PEF的平均差异为9.82（95%可信区间：2.43 - 17.21），FEV₁的平均差异为0.17（95%可信区间：0.12 - 0.21）。PEV₁的组内相关系数为0.96（p <0.001；95%可信区间：0.93 - 0.97），PEF的组内相关系数为0.93（p<0.0001；95%可信区间：0.89 - 0.95）。
