Reference values for respiratory system impedance using impulse oscillometry in healthy preschool children
Jye Hae Park, Jung Won Yoon, Youn Ho Shin, Hye Mi Jee, Young Sun Wee, Sun Jung Chang, Jung Hwa Sim, Hye Yung Yum, Man Yong Han
Clin Exp Pediatr. 2011;54(2):64-68.   Published online February 28, 2011
Purpose

The normal values for lung resistance and lung capacity of children, as determined by impulse oscillometry (IOS), are different for children of different ethnicities. However, reference values there is no available reference value for Korean preschool children have yet to be determined. The aim of the present study was to determine the normal ranges of IOS parameters in Korean preschool...

The quality control and acceptability of spirometry in preschool children
Hyun Kyong Seo, Sun Jung Chang, Da Woon Jung, Young Sun Wee, Hye Mi Jee, Ji Young Seo, Man Yong Han
Clin Exp Pediatr. 2009;52(11):1267-1272.   Published online November 15, 2009
Purpose : We examined the ability of preschool aged children to meet the American Thoracic Society (ATS) and European Resiratory Society (ERS) goals for spirometry quality and tried to find out the major factor for improving the rate of success of spiromety test in this age group. Methods : Spirometry was performed in 2-6 aged 155 children with chronic cough or...
Early stress hyperglycemia as independent predictor of increased mortality in preterm infants
Young Sun Wee, Gae Hyun Ahn, Eun Gyong Yoo, In Sook Lim, Kyu Hyung Lee
Clin Exp Pediatr. 2008;51(5):474-480.   Published online May 15, 2008
Purpose : Stress hyperglycemia is common in critically ill adult patients. It is known as a predictor of increased mortality, and intensive insulin therapy has been shown to improve the prognosis in such patients. We have investigated the relationship between early stress hyperglycemia and clinical outcomes in preterm infants. Methods : In this study, 141 preterm infants with a gestational age...
Reference values for respiratory system impedance using impulse oscillometry in school-aged children in Korea
Young Sun Wee, Hyoung Yun Kim, Da Wun Jung, Hye Won Park, Yoon Ho Shin, Man Yong Han
Clin Exp Pediatr. 2007;50(9):862-867.   Published online September 15, 2007
Purpose : The impulse oscillometry (IOS) is applicable to young children because it requires minimal cooperation and a non-invasive method to measure the mechanics of respiratory system. This study aimed to develop the reference values in school-aged children in Korea, using IOS which is a modification of forced oscillation technique (FOT). Methods : Measurements were performed in 92 previously untrained healthy...
