Pulmonary function was measured in 35 patients (mean age 11.6 years) with simple complete transposition 4.4 years after intracardiac repair. A disturbance in the lung function (greater than 2 SD from the normal value) was found in 88% of the patients. A marked increase in static recoil pressure (P less than 0.001) was most frequent (in 66%). Static lung(More)
Lung volume, indices of lung elasticity and airway patency were measured in 74 patients, 9-21 yr old (15.0 +/- 2.5 yr) with atrial septal defect (secundum type) from 2-11 (5.1 +/- 2.5) yr after successful surgical correction. Clinical condition in all patients was classified as excellent. Heart surgery was performed at the age of 4-14.8 (9.9 +/- 3.0) yr.(More)
OBJECTIVE To test the effect of heart disease and heart surgery on lung function. DESIGN A pulmonary function study of children undergoing surgery for atrial septal defect (ASD). SETTINGS University hospital. PATIENTS 26 children tested before surgery (at mean (SD) age 11.8 (3.8) years) and 24 patients tested 1.8 (0.2) years after surgical correction.(More)
Lung function of 65 patients who had idiopathic interstitial pulmonary fibrosis (IIPF) that had been treated with prednisone was evaluated by tests of ventilatory function, lung mechanics, and gas exchange at rest and during exercise. Ages on initial investigation ranged from 5 to 20 years. In 35 of 65 patients the studies were repeated an average of four(More)
In the article we outlined the basic principles of some recent methods of lung function testing, suitable for the assessment of airway obstruction in children and adolescents. There is also a brief description of various methods, normal values expressed in a form of regression equations, significance of different methods for the assessment of airway(More)
We evaluated changes of maximum expiratory flow-volume (MEFV) curves and of partial expiratory flow-volume (PEFV) curves caused by bronchoconstrictor drugs and dust, and compared these to the reverse changes induced by a bronchodilator drug in previously bronchoconstricted subjects. Measurements of maximum flow at constant lung inflation (i.e. liters(More)
Static lung volumes, pressure-volume curves, airway conductance (Gaw) and maximum expiratory flow-volume curves were obtained in a group of healthy children and adolescents (age 6 to 17 years, body height 115 to 180 cm). Relating lung recoil pressure to maximum expiratory flow at the same lung volume level allowed the calculation of the conductance of the(More)
Static (Cst(L)), dynamic (Cdyn(L)), and "specific lung compliance (CL/TLC, CL/FRC) and the elastic recoil pressure of the lungs (Pst/(L)) were measured in 131 healthy children and the adolescents (age 6 to 17 years) from simultaneous recordings of esophageal pressure and lung volume. Esophageal elastance and vertical esophageal pressure gradients were also(More)
In a group of 173 healthy preschool children 3-6 years of age (body height, 90-130 cm; 102 boys and 71 girls) out of total 279 children examined, maximum expiratory flow-volume (MEFV) curves were recorded in cross-sectional measurements. The majority (62%) of preschool children were able to generate an MEFV curve as correctly as older children. From the(More)
