The aim of this study was to assess the feasibility and accuracy of a novel magnetic resonance-compatible (MRc)-spirometer. The influence of body posture, magnetic resonance (MR)-setting and image acquisition on lung function was evaluated. Dynamic MR imaging (dMRI) was compared with simultaneously measured lung function. The development of the MRc-spirometer was based on a commercial spiromete...

Severe alpha1-antitrypsin (AAT) deficiency predisposes to emphysema development. Highly variable rates of decline in lung function are reported in PiZZ individuals. The annual decline in forced expiratory volume in one second (FEV1; delta FEV1) was analysed in relation to smoking status in a cohort of 608 adult PiZZ individuals included in the Swedish national AAT deficiency register. Delta FEV...

Little is known about survival and clinical prognostic factors in females with chronic obstructive pulmonary disease (COPD). The aim of the present study was to determine the survival difference between males and females with COPD and to compare the value of the different prognostic factors for the disease. In total, 265 females and 272 males with COPD matched at baseline by BODE (body mass ind...

Current reference values for diurnal peak flow variation in healthy children (median 8.2%; 95th percentile 31%) are so high that considerable overlap exists with those of asthmatic children. These values have been obtained using written peak flow diaries, which are unreliable. The aim of the present study was to obtain reliable reference values for the variation in peak flow and forced expirato...

PURPOSE We report surgical results of lung cancer associated with postobstructive pneumonia. MATERIALS AND METHODS We report on morbidity and mortality, and we analyze the risk factors for them and the prognostic factors for overall survival of patients without mortality. RESULTS Morbidity developed in 13 of the 38 patients (34.2%). Mortality rate was 10.5%. Hemoglobin concentration before ...

OBJECTIVE(S) As not only few evidences but also contradictory results exist with regard to the effects of resistance training (RT) and resistance plus endurance training (ERT) on respiratory system, so the purpose of this research was therefore to study single and concurrent effects of endurance and resistance training on pulmonary function. MATERIALS AND METHODS Thirty seven volunteer health...

Lung function has been associated with mortality after adjusting for other risk factors; however, few studies have adjusted for physical fitness and reported separate analyses according to smoking status. In 1972-1975, spirometry, clinical and physiological parameters were recorded in 1,623 apparently healthy males aged 40-59 yrs. After 26 yrs of follow-up, the current authors investigated the ...

Mean lung density (dm) and radiologic (VLx) lung volume can be calculated using CT scan data. As many emphysematous patients are overdistended, the analysis of dm alone could be meaningless. However, lung mass (m) can be calculated as the product of dm and VLx. Twenty-four patients suspected of mild or severe emphysema as judged by roentgenographic and physiologic examinations as well as 16 hea...

background: the study was aimed to explore the association between arterial oxygen saturation (spo2) and spirometer parameters of disease severity in copd patients with a view to identify whether the pulse oximetry can be used as an alternative to arterial values in the clinical management of copd patients in a routine practice. materials and methods: thirty-one patients with copd were included...
