Background: The present study (1) characterizes a physiologic phenotype of restrictive dysfunction due to airway injury and (2) compares this phenotype to the phenotype of interstitial lung disease (ILD). Methods: This is a retrospective study of 54 persistently symptomatic subjects following World Trade Center (WTC) dust exposure. Inclusion criteria were reduced vital capacity (VC), FEV 1 /VC . 77%, and normal chest roentgenogram. Measurements included spirometry, plethysmography, diffusing capacity of lung for carbon monoxide (D LCO ), impulse oscillometry (IOS), inspiratory/expiratory CT scan, and lung compliance (n 5 16). Results: VC was reduced (46% to 83% predicted) because of the reduction of expiratory reserve volume (43% Ϯ 26% predicted) with preservation of inspiratory capacity (IC) (85% Ϯ 16% predicted). Total lung capacity (TLC) was reduced, confi rming restriction (73%

“…The two main factors that constitute impedance are resistance (R) and reactance (X). It is measured between certain frequencies (5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20). When R and X are measured at 5 Hz, they are named R5 and X5.…”

Aim: The aim of this study was to evaluate the pulmonary functions of preschool children born late-preterm. Material and Methods:Children aged between 3-7 years who were born at 34 0/7 -36 6/7 weeks' gestation represented the target sample. Patients with a diagnosis of congenital cardiac, pulmonary and/or muscle diseases were excluded. Respiratory symptoms were evaluated using the modified asthma predictive index and International Study of Asthma and Allergies in Childhood criteria for children aged under and over 6 years, respectively. Skin prick tests were performed. Age-matched healthy controls were chosen according to the criteria proposed by the American Thoracic Society. Lung functions were evaluated using impulse oscillometry study in both groups. Data were recorded in the SPSS program.Results: A total of 139 late-preterms and 75 healthy controls participated in the study. The mean gestational week of the late-preterms was 35.3±0.9 weeks. The main admission diagnosis to neonatal intensive care unit was respiratory distress. In the postdischarge period, 54.1% were hospitalized for pulmonary infections at least once, and 57.8% were passive smoking currently. Aeroallergen sensitivity was detected as 25.8% in the late-preterm group; 34.5% and 15.1% were diagnosed as having asthma and non-asthmatic atopy, respectively. Impulse oscillometry study parameters of R5, R10, and Z5 were higher and X10 and X15 were lower in late-preterms than in controls (p<0.05). Late-preterms with and without respiratory distress in the postnatal period revealed no statistical differences for any parameters. Conclusions:Our findings suggest that presence of increased peripheral airway resistance in late-preterms as compared to term-born controls. (Turk Pediatri Ars 2017; 52: 72-8)

“…Impulse oscillometry might be useful as an indirect measure of airflow obstruction and helpful in persons not able to perform forced breathing maneuvers required during the spirometry test. The impulse oscillometry test has been used for many years to measure changes in the airways of children with lung problems such as asthma and cystic fibrosis [Song et al 2008;Komarow et al 2011;Shi et al 2012;Schulze et al 2016]. More recently, impulse oscillometry has been used to investigate lung problems in adults exposed to dust or chemicals, such as World Trade Center emergency responders and soldiers returning from deployment overseas [Oppenheimer et al 2007;Berger et al 2013;Weinstein et al 2016].…”
