The quality of the spirometry is estimated with criteria of acceptability and repeatability. The repeatability criteria accepted by consensus is < 0.150 L.
To know the repeatability in quality A spirometry.
Analytical cross-sectional design. The demographic variables and the 3 best spirometry curves with normal, suggestive of restriction and bronchial obstruction profiles were obtained from consecutive subjects of both genders from 18 to 80 years of age. The repeatability was analyzed with the mean difference (bias) and the intraclass correlation coefficient.
630 curves from 210 subjects were accepted. Group age 60 ± 15 years. Female predominance 113 (53.8%), occupation: domestic services 61 (29%), and diagnosed with chronic obstructive pulmonary disease: 70 (33.4%). The differences in the curves were < 0.150 L. The mean difference (bias) and the intraclass correlation coefficient (95% confidence interval, 95% CI) of the forced expiratory volume in the first second were 1 vs. 2 maneuver: -0.01 (0.13, -0.14), 0.997 (95% CI 0.996, 0.998); 2 vs. 3 maneuver: 0.00 (0.13, -0.13), 0.997 (95% CI 0.996, 0.998), and maneuver 1 vs. 3: -0.00 (0.16, -0.17), 0.995 (95% CI 0.994, 0.996). Forced vital capacity: 1 vs. 2 maneuver: -0.01 (0.17, -0.18), 0.996 (95% CI 0.995, 0.997); 2 vs. 3 maneuver: 0.01 (0.17, -0.16), 0.997 (95% CI 0.0.996, 0.998), and maneuver 1 vs. 3: -0.00 (0.18, -0.19), 0.996 (95% CI 0.995, 0.997).
The repeatability obtained in spirometry with quality A validates the use of the repeatability criterion of 0.150 L.
通过可接受性和重复性标准评估肺量计检查的质量。经共识认可的重复性标准为<0.150升。
了解A类质量肺量计检查的重复性。
采用分析性横断面设计。从18至80岁的连续两性受试者中获取人口统计学变量以及3条最佳的具有正常、提示限制性和支气管阻塞特征的肺量计曲线。通过平均差异（偏差）和组内相关系数分析重复性。
接受了来自210名受试者的630条曲线。年龄组为60±15岁。女性占优势，有113人（53.8%），职业：家政服务61人（29%），被诊断为慢性阻塞性肺疾病：70人（33.4%）。曲线差异<0.150升。第一秒用力呼气量的平均差异（偏差）和组内相关系数（95%置信区间，95%CI）在第1次与第2次测量之间为：-0.01（0.13，-0.14），0.997（95%CI 0.996，0.998）；第2次与第3次测量之间为：0.00（0.13，-0.13），0.997（95%CI 0.996，0.998），第1次与第3次测量之间为：-0.00（0.16，-0.17）, 0.995（95%CI 0.994，0.996）。用力肺活量：第1次与第2次测量之间为：-0.01（0.17，-0.18），0.996（95%CI 0.995，, 0.997）；第2次与第3次测量之间为：0.01（0.17，-0.16），0.997（95%CI 0.996，0.998），第1次与第3次测量之间为：-0.00（0.18，- , 0.19），0.996（95%CI 0.995，0.997）。
A类质量肺量计检查所获得的重复性验证了0.150升重复性标准的应用。
