Reference values for respiratory system impedance using impulse oscillometry in healthy preschool children
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...
متن کاملReference values for respiratory system impedance by using impulse oscillometry in children aged 2-11 years.
The forced oscillation technique makes it possible to evaluate the mechanical properties of the respiratory system with a minimum of cooperation. The method is therefore especially useful in children. Impulse oscillometry (IOS) is a commercially available version of this technique. There is, as yet, limited information on reference values for IOS in children. The aim of this study was to extend...
متن کاملValues of impulse oscillometry in healthy mexican children and adolescents.
BACKGROUND The impulse oscillometry system (IOS) is increasingly used to evaluate lung function, but individual results must be compared with appropriate reference values. We aimed to obtain such reference values in Mexican children and adolescents. METHODS Healthy subjects were recruited from kindergartens and schools after their parents signed a consent letter. Respiratory system impedances...
متن کاملReference Values of Lymphocyte Sub-Populations in Healthy Human Immunodeficiency Virus-Negative Iranian Adults
Background: Lymphocyte subsets enumeration is considered prominent in the management of primary and acquired immunodeficiency disorders. Because of local variations due to race, age, gender, and environmental conditions on lymphocyte subsets, and to improve the accuracy of interpretation of laboratory findings, reference intervals must be determined in every population. Objective: To establish ...
متن کاملLevels - Reference Values in Healthy Pakistani Adults
Hemoglobin A 2 (HbA 2 ) was quantitated in blood from 212 healthy Pakistani adults with an age range of 16 to 60 years. HbA 2 level was observed in the range of 1.20 to 3.80% with mean ± SD as 2.67 ± 0.66% for both sexes. The mean level for males and females was 2.67 ± 0.66% and 2.66 ± 0.69% respectively. These values showed no significant difference (P > 0.1) among both sexes. The coefficient ...
