BACKGROUND The Global Initiative for Obstructive Lung Diseases (GOLD) defines COPD as a disease that is usually progressive. GOLD also provides a spirometric classification of airflow limitation. However, little is known about the long-term changes of patients in different GOLD grades. OBJECTIVE Explore the proportion and characteristics of COPD patients that change their spirometric GOLD gra...

BACKGROUND How different Global Initiative for Chronic Obstructive Lung Disease (GOLD) classifications of chronic obstructive pulmonary disease (COPD) predict mortality is unclear. OBJECTIVE To examine the association of spirometric GOLD grades and the new ABCD groups with mortality, and to compare their informativeness in relation to mortality. METHODS We studied 1540 people with post-bron...

Electronic spirometers offer the prospect of paperless home monitoring, but data quality is not automatically better than from conventional monitoring. The aim of this study was to determine the extent to which the quality and processing of self-recorded spirometric data from patients with asthma complied with international guidelines for spirometry. Data were from 33 subjects with poorly contr...

INTRODUCTION Spirometry is the basic method used to diagnose and monitor obstructive diseases. Spirometric tests are performed in more and more people of advanced age (more than 65 years old). The objective of the study was to assess the quality of spirometry (measurement of the flow-volume curve) in subjects of the aforementioned age group, with reference to applicable quality criteria specifi...

Ageing is a natural process. Senescence an expression used for the deterioration in vitality or lowering of biological efficiency that accompanies ageing. Respiratory system undergoes various anatomical, physiological and immunological changes with age. Lungs mature at age 20 to 25 years, then it decreases about 200 250cc every 10 years from Among elderly health problems, respiratory conditions...

BACKGROUND Recent studies have repeatedly shown weak correlations among lung function parameters, atopy, exhaled nitric oxide level (Feno), and airway inflammatory markers, suggesting that they are non-overlapping characteristics of asthma in adults. A study was undertaken to determine, using factor analysis, whether the above features represent separate dimensions of childhood asthma. METHOD...
