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.<br />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.<br />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.<br />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.
