INTRODUCTION Prevention of pulmonary complications after coronary artery bypass graft is attended as a very important issue. The aim of this study was to evaluate the role of pulmonary rehabilitation before surgery for reducing the risk of pulmonary complications after surgery. METHODS In a randomized clinical trial, 60 patients undergoing heart surgery were randomly divided into two groups A...

BACKGROUND The diagnosis of COPD is dependent upon clinical judgment and confirmation of the presence of airflow obstruction using spirometry. Spirometry is now routinely available; however, spirometry incorrectly performed or interpreted can lead to misdiagnosis. We aimed to determine whether spirometry undertaken in primary care for patients suspected to have COPD was of sufficient quality an...

BACKGROUND Objective measurement of airflow obstruction by spirometry is an essential part of the diagnosis of asthma or COPD. During exacerbations, the feasibility and utility of spirometry to confirm the diagnosis of asthma or chronic obstructive pulmonary disease (COPD) are unclear. Addressing these gaps in knowledge may help define the need for confirmatory testing in clinical care and qual...

background the relationship between gastroesophageal reflux (gerd) and airway diseases is still a matter of debate. oscillometry is an objective, independent tool for the evaluation of airway resistance. the main purpose of this study is to comparespirometry and oscillometry results before and after treatment by a proton pump inhibitor (ppi) in a group of gerd patients who have no respiratory s...

introduction: adenotonsillar hypertrophy is a typical cause of surgery in children. evaluation and identification of patients as potential candidates tonsillectomy is a primary concern for otolaryngologists. this study focuses on the results of pulmonary function tests (pfts) after tonsillectomy in children. materials and methods: this cross-sectional study examined 50 patients suffering from t...

BACKGROUND We recently demonstrated that quality of spirometry in primary care could markedly improve with remote offline support from specialized professionals. It is hypothesized that implementation of automatic online assessment of quality of spirometry using information and communication technologies may significantly enhance the potential for extensive deployment of a high quality spiromet...

cement dust exposure is associated with increased respiratory impairment. as the major occupational hazard in the cement production industry is cement particles, our aim was to more thoroughly examine the acute effects of occupational exposure to cement dust on the respiratory system. a cross-shift study was conducted in a cement factory in iran. 100 high exposed workers from production and pac...

Chronic Obstructive Pulmonary Disease (COPD) is one of the most common chronic conditions. The current assessment COPD requires a maximal maneuver during spirometry test to quantify airflow limitations patients. Other less invasive measurements such as thoracic bioimpedance and myographic signals have been studied an alternative classical methods they provide information about respiration. Part...
