Pulmonary function test is one of the most important tools in the management of patients with respiratory tract diseases and allergic diseases. As with the difficulties in performing the test, it has been seldom used in pediatric field. But with
the
advent of simple, computerized tools, pediatric pulmonologist and allergist try to manage the patients using PFT. Still the normal predicted values are variable among the reports. So it is important to have normal predicted value in Korean
children.
From April to July 1992, pulmonary function test was performed in 965(male: 490, female: 475) primary school-aged children except <3 or >97 percentile of Korean-children Physical developemental standards with history of allergic diseases and
respiratory
tract diseases ay SungNam, KyongKiDo. We evaluated the predicted normal values of the FEV1.0, FVC and PEFR and logarithmic regression equation setting the predicted values by using the microspirometer of Micromedical Ltd. England that could that
could
be easily applied to children.
1) Predicted values of pulmonary function test items were generally higher in boys than those of girls.
2) Correlation coefficient to the parameters examined was the highest in height 0.78, then age 0.75, weight 0.70 and chest circumference 0.61.
