Impact of obesity on pulmonary function of preschool children: an impulse oscillometry study

Question: Does obesity in preschool children affect lung function, and which obesity indices can predict such alterations?
Finding: Preschool children with obesity exhibit impaired lung function characterized by elevated total and peripheral airway resistance. Waist-to-height ratio was the strongest predictor of such changes.
Meaning: Early obesity prevention and treatment are needed. Monitoring waist-to-height ratio, body weight, and body mass index may help identify children at risk of altered lung function.

· Hypertension is defined as a blood pressure (BP) >90th (elevated) or 95th (hypertension) percentile in children by height, age, and sex and >95th percentile in neonates by age, birth weight, and sex.
· Although the oscillometric method can be used for screenings, the auscultatory method remains the gold standard. The hybrid method employs the auscultatory and electronic methods and can reduce bias.
· BP measurement mobile device applications have a potential for development.

A comparison between impulse oscillometry system and spirometry for spirometry for detecting airway obstruction in children

Hae Young Hur, Ji Hee Kwak, Hyoung Yun Kim, Da Wun Jung, Yoon Ho Shin, Man Yong Han

Clin Exp Pediatr. 2008;51(8):842-847. Published online August 15, 2008

Purpose : Measurement of forced expiratory volume in 1 second (FEV1) is usually difficult to obtain in children under six years of age because it requires active cooperation. This study evaluates the sensitivity of impulse oscillometry system (IOS) parameters for detecting airway obstruction in comparison with FEV1. Methods : We studied 174 children who performed the lung function and methacholine challenge...

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...

Indirect Measurement of Blood Pressure in Neonates Using an Automatic Noninvasive Oscillometric Monitor

Jung Hea Park, Hea Jin Choeh, Eun Sik Kang, Chong Sung Chung, Kyuchul Choeh

Clin Exp Pediatr. 1993;36(9):1211-1218. Published online September 15, 1993

The measurement of blood pressure in neonates is an important diagnostic procedure. But the measurement of blood pressure has not been performed routinely because of difficulty in measuring blood pressure and varable normal range according to measuring apparatus. Recently some accurate and convenient apparatus of measuring blood pressure have been introduced in neonatal care, so the reference values...
