Spirometry at adolescence.

Residual volume (RV), functional residual capacity (TGV) and total lung capacity (TLC) have been measured in 42 adolescents aged 16-22 years (22 young men and 20 young women) and in 60 children aged 12-15 years (29 boys and 31 girls) who were selected as having the same ranges of heights. TLC and TGV were related to height in each age and sex group; the slope of the regression curves did not differ between subgroups. RV was related to height in the boys and girls and not in the adolescents; however the number of subjects in each group was small. Relative to height the residual volumes of boys and girls were similar and in both sexes were larger than those for adolescents. Amongst the latter the values for young women were smaller than those for young men. The possible mechanisms are discussed.

Nitrogen single breath test, flow-volume curves and spirometry in healthy children, 7-18 years of age.

One hundred and forty school children, 75 boys and 65 girls, aged 7-18 years, underwent the following lung function tests: closing volume, slope of the alveolar plateau, maximal expiratory and inspiratory flows at 75, 50 and 25% of vital capacity, static and dynamic lung volumes. Lung volumes and maximal flows increase with height in an exponential way, the exponents varying between 2.6 and 3.1, while closing volume in per cent of vital capacity and the slope of the alveolar plateau decrease linearily with increasing height. Regression equations are given for each sex with height as determinant.

Office spirometry.

The practicality of the office spirometer as an effective, inexpensive diagnostic device is well established. It can be used in a matter of seconds by minimally trained office personnel. Two basic parameters can be quickly and accurately measured: forced vital capacity (FVC), a test of volume indicative of restrictive lung disease, and forced expiratory volume in one second (FEV1), a test of flow rate indicative of obstructive lung disease. The FEV1/FVC ratio is a valuable screening measurement that indicates the likelihood of progressive deterioration of pulmonary function.

[Comparison of the oscillatory measurement of airway resistance with plethysmography and spirometry in juvenile patients].

In 78 children (age 4 to 17 years, height 102 to 179 cm) with and without clinical signs of airway obstruction, spirometric and plethysmographic measurements were compared with the forced oscillation method for determination of resistance to breathing (Ros). Ros was measured with a recently developed apparatus (Siregnost FD5. Siemens) and showed a close correlation with resistance (r = 0.84; n = 78). The spirometric values did not, however, exhibit a definite relationship to Ros. This study demonstrates that airway obstruction in children can be equally well estimated by oscillatory and plethysmographic techniques. Compared with plethysmography, determination of Ros has the particular advantage of being better tolerated by young subjects.
