Impulse oscillometry system: association with pulmonary function in patients with COPD and healthy subjects.
Background: Spirometry is the gold-standard diagnosis test for COPD. However, the impulse oscillometry system (IOS) has proven to be effective for early detection of COPD and little is known about the association between the two techniques in the presence or absence of pulmonary disease.

However, the impulse oscillometry system (IOS) has proven to be effective for early detection of COPD and little is known about the association between the two techniques in the presence or absence of pulmonary disease. Objective: To investigate the association between lung function and lung mechanics using the IOS in patients with COPD and healthy subjects. Methodology: Eighteen patients with COPD and 18 healthy individuals performed spirometry and the IOS. Results: FEV1 and FEF25-75% correlated with X5Hz (r=0.74; r=0.63), and with R5Hz-R20Hz (r=-0.67; r=- 0.51), and FVC moderately correlated with most of the oscillometric parameters (R5Hz, Z5Hz, R5Hz – R20Hz, X5Hz and Fres) in the COPD group. Conclusions: Reactance is related to pulmonary airflow obstruction and peripheral resistance is associated with mean forced expiratory flow. Thus, IOS is a method that can complement spirometric findings in patients with COPD. Introdução: A espirometria é o padrão ouro para diagnosticar a DPOC. Contudo, o sistema de oscilometria de impulso (IOS) tem se mostrado eficaz no diagnóstico precoce da doença e pouco se sabe sobre a associação entre as técnicas na presença e na ausência de doença. Objetivo: Investigar a associação entre função e mecânica pulmonar utilizando o IOS em indivíduos saudáveis e com DPOC. Métodos: Dezoito indivíduos com DPOC e 18 saudáveis realizaram espirometria e IOS. Resultados: O VEF1 e FEF25-75% correlacionaram com X5Hz (r=0,74, r=0,63) e com R5Hz-R20Hz (r=-0.67, r=-0,51); a CVF correlacionou moderadamente com a maioria das variáveis oscilométricas (R5Hz, Z5Hz, R5Hz–R20Hz, X5Hz e Fres) no grupo com DPOC. Conclusões: A reatância está relacionada com a obstrução ao fluxo aéreo pulmonar e a resistência periférica está associada com o fluxo expiratório forçado médio. Portanto, o IOS é um método que pode complementar os achados espirométricos em pacientes com DPOC. pubtype: Academic Journal doctype: research tables/charts Journal Article ougenre: Article language: English refInfo: holdings: @attributes: islocal: N |
