“…As for the feasibility of RO and spirometry, there are two studies that can be directly compared with our own. Gunawardana et al, 31 in a small sample (47 patients), clinically similar to ours (children 5 to 16-year-old with wheezing or asthma) and using the same RO commercial equipment, found a much greater difference (98% vs. 68%) in the probability of obtaining valid RO and spirometry, and also a somewhat greater correlation between RO and oscillometry results…”

Objective The purpose of this study was to describe the feasibility of respiratory oscillometry (RO) in schoolchildren with asthma, and the concordance of its results with those of spirometry, to determine its clinical usefulness. Methods RO and spirometry were performed in 154 children (6 to 14‐year‐old) with asthma, following strict quality criteria for the tests. Their feasibility (probability of valid test, time of execution, number of maneuvers needed to achieve a valid test, and perceived difficulty) was compared. The factors that influence feasibility were analyzed with multivariate methods. FEV1, FEV1/FVC, FVC and FEF25‐75 for spirometry, and R5, AX and R5‐19 for RO, were converted into z‐scores and their concordance was investigated through intraclass correlation coefficients (ICC) and kappa indices for normal/abnormal values. Results There were no differences in the probability of obtaining a valid RO or spirometry (83.1% vs. 81.8%, p = 0.868). RO required a lower number of maneuvers [mean (SD) 4.2 (1.8) versus 6.0 (1.6), p < 0.001] and less execution time [5.1 (2.7) versus 7.6 (2.4) minutes, p < 0.001], and patients considered it less difficult. Age increased the probability of obtaining valid RO and spirometry. The concordance of results between RO and spirometry was low, and only between zFEV1 and zAX could it be considered moderate (ICC = 0.412, kappa = 0.427). Conclusion RO and spirometry are feasible in children with asthma. RO has some practical advantages, but the concordance of its results with spirometry is low.

IntroductionThis study compares home‐based oscillometry and spirometry for characterizing respiratory system disease in school‐aged children with bronchopulmonary dysplasia (BPD) in clinical research. We hypothesized higher rates of successful completion and abnormal cases identified through oscillometry, with correlations between device measurements.MethodsParticipants 6–12 years old with BPD in the ongoing Air Quality, Environment and Respiratory Outcomes in BPD (AERO‐BPD) study performed oscillometry followed by spirometry at two separate home visits. Parameters measured included airway resistance at 5 Hz(R5), resistance from 5 to 19 Hz(R5‐19), resonance frequency(Fres), reactance at 5 Hz(X5), area under the curve between Fres and X5(AX), forced expiratory volume in 1 second(FEV1), forced vital capacity(FVC), and FEV1/FVC. Descriptive statistics identified the proportion of successful tests, correlation in measurements, and rate of lung disease for each device.ResultsAmong 76 subjects with 120 paired observations, 95% and 71% of participants successfully performed oscillometry and spirometry, respectively, at home visit one. 98% and 77% successfully performed oscillometry and spirometry, respectively, at home visit two. Odds ratios favored oscillometry (range 5.31–10.13, p < 0.01). FEV1 correlated with AX (correlation coefficient r = −0.27, p = 0.03); FEV1/FVC with AX (r = −0.32, p = 0.02); and FEV1/FVC with R5 (r = −0.37, p = 0.01). AX exhibited the highest prevalence of abnormality at 25%; other oscillometry parameters ranged from 5%–22%. Forty‐five to sixty‐four percent of participants had abnormal spirometry. Oscillometry assessments had significantly lower odds of capturing lung disease (odds ratios 0.07–0.24, p < 0.0001).ConclusionsSchool‐aged children with BPD demonstrated higher success rates in field‐based oscillometry than spirometry. Spirometry exhibited higher rates of abnormality than oscillometry. Moderate correlation exists between device measurements.
