Abstract
OBJETIVO: Avaliar a confiabilidade intra-examinador e inter-examinadores da cirtometria (conjunto de medidas das circunferências de tórax e abdômen durante os movimentos respiratórios) e sua correlação com volumes pulmonares medidos por meio da pletismografia respiratória por indutância. MÉTODOS: Quarenta indivíduos saudáveis, com média de idade de 28 anos, foram avaliados. As medidas foram realizadas em decúbito dorsal em três momentos: em repouso, em inspiração máxima e em expiração máxima. Dois examinadores treinados, os quais foram cegados, realizaram as medidas. Utilizou-se o teste de Friedman para avaliar a confiabilidade intra-examinador e foram utilizados o teste de Wilcoxon e o coeficiente de correlação intraclasse para avaliar a confiabilidade inter-examinadores. A correlação entre os resultados da cirtometria e da pletismografia foi obtida por meio do coeficiente de correlação de Spearman. Para todos os testes, considerou-se um nível de significância estatística de 0,05. RESULTADOS: Os resultados mostraram confiabilidade intra-examinador adequada. Em relação à confiabilidade inter-examinadores, foram observadas diferenças estatisticamente significativas (de no máximo 2,8 cm) em todas os conjuntos de medidas.No entanto, por meio da análise do coeficiente de correlação intraclasse, observou-se que os examinadores foram responsáveis apenas por pequena parte da variabilidade (1,2-5,08%) observada entre as medidas. Quando as medidas da cirtometria foram comparadas aos volumes pulmonares medidos por meio da pletismografia respiratória por indutância, encontraram-se correlações de baixa magnitude (variação de r = 0,170-0,343). CONCLUSÕES: Os resultados deste estudo sugerem que a cirtometria constitui uma medida precisa, mas não acurada, para aferir volumes pulmonares.
ABSTRACT OBJECTIVE: To determine the intrarater and interrater reliability of cirtometry (measurements of the circumference of the chest and abdomen taken during respiratory movements) as well as its correlation with pulmonary volumes measured by respiratory inductive plethysmography. METHODS: A total of 40 healthy individuals were evaluated. The mean age was 28 years. The measurements were taken in the supine position at three different time points: at rest, at maximal inspiration, and at maximal expiration. Two trained investigators, each of whom was blinded as to the results obtained by the other, performed the measurements. The Friedman test was used to determine intrarater reliability, and the Wilcoxon test, together with the intraclass correlation coefficient, were used to determine interrater reliability. The correlation between the cirtometry measurements and the plethysmography results was obtained using Spearman's correlation coefficient. The level of significance was set at 0.05 for all tests. RESULTS: Intrarater reliability was satisfactory. Regarding interrater reliability, statistically significant differences (2.8 cm at the most) were found in all sets of measurements. However, through the analysis of the intraclass correlation coefficient, the investigators were found to be responsible only for a small portion of the variability (1.2-5.08%) found among the measurements. When the cirtometry measurements were compared to the volumes measured by respiratory inductive plethysmography, low correlations (range, r = 0.170-0.343) were found. CONCLUSIONS: The findings of this study suggest that, although cirtometry is a reliable measurement, it does not accurately measure pulmonary volumes.
