UNASSIGNED: The quality of the spirometry is estimated with criteria of acceptability and repeatability. The repeatability criteria accepted by consensus is < 0.150 L.
UNASSIGNED: To know the repeatability in quality A spirometry.
UNASSIGNED: 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.
UNASSIGNED: 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).
UNASSIGNED: The repeatability obtained in spirometry with quality A validates the use of the repeatability criterion of 0.150 L.
UNASSIGNED: la calidad de la espirometría se estima con criterios de aceptabilidad y repetitividad. La repetitividad aceptada por consenso es < 0.150 L.
UNASSIGNED: conocer la repetitividad en espirometrías de calidad A.
UNASSIGNED: diseño transversal analítico. Se obtuvieron las variables demográficas y las 3 mejores curvas de espirometría con perfil normal, que sugiriera restricción y obstrucción bronquial de sujetos consecutivos de ambos géneros de 18 a 80 años. La repetitividad se analizó con la diferencia de medias (sesgo) y el coeficiente de correlación intraclase.
UNASSIGNED: se aceptaron 630 curvas de 210 sujetos. Edad grupal 60 ± 15 años. Predominio femenino 113 (53.8%), ocupación: servicios domésticos 61 (29%) y con enfermedad pulmonar obstructiva crónica 70 (33.4%). Las diferencias en las curvas fueron < 0.150 L. Las diferencias medias (sesgo) y el coeficiente de correlación intraclase (intervalo de confianza al 95%, IC 95%) del volumen espiratorio forzado en el primer segundo fueron: maniobra 1 frente a 2: −0.01 (0.13, −0.14), 0.997 (IC 95% 0.996, 0.998); maniobra 2 frente a 3: 0.00 (0.13, −0.13), 0.997 (IC 95% 0.996, 0.998), y maniobra 1 frente a 3: −0.00 (0.16, −0.17), 0.995 (IC 95% 0.994, 0.996). La capacidad vital forzada: maniobra 1 frente a 2: −0.01 (0.17, −0.18), 0.996 (IC 95% 0.995, 0.997); maniobra 2 frente a 3: 0.01 (0.17, −0.16), 0.997 (IC 95% 0.0.996, 0.998), y maniobra 1 frente a 3: −0.00 (0.18, −0.19), 0.996 (IC 95% 0.995, 0.997).
UNASSIGNED: la repetitividad obtenida en espirometrías con calidad A valida el uso del criterio de repetitividad de 0.150 L.
