results fifty-seven patients were enrolled; 35 patients (62.5 %) were male. the mean of etco2 and paco2 of patients were 41.49 ± 9.80 and 64.74 ± 9.76, respectively. the mean of paco2 was significantly more than the means of etco2 in patients with copd. the association between arterial bicarbonate and etco2 was weak and not significant (p = 0.136 and r = 0.04). conclusions capnography can be us...

conclusions these results showed the preventive effect of hydroethanolic extract of n. sativa on tracheal responsiveness of guinea pig model of copd, which was as effective as vitamin c. results the tracheal responsiveness to both methacholine and ovalbumin in guinea pigs with copd were significantly higher than those of controls (p < 0.001 for both cases). the tracheal responsiveness in the co...

background and purpose: despite the high prevalence of chronic obstructive pulmonary disease, there haven,t been definite curative treatment for the disease and focus of treatment has directed towards pulmonary rehabilitation as an effective non-drug treatments. this study were performed to determine the effect of motivational abdominal breathing device on breathing pattern and dyspnea of chron...

background :chronic obstructive pulmonary disease (copd) is a third leading cause of death.   methods : in this case control study, we prepared 5 cc bloods from the antecubital vein of 100 copd patients and 40 healthy individuals as control group. vascular endothelial growth factor (vegf) expression protein level was measured by elisa in both groups.   results : we found that concentration of v...

introduction:the overlap syndrome, consisting ofobstructive sleep apnea hypopnea syndrome (osahs) and chronic obstructvie pulmonary disease (copd) is a major problem in copd patients. oshas corresponds to the likelihood of systemic hypertension.the present study was aimed to evaluate the association between apnea-hypopnea index and diastolic blood presssure (dbp) in overlap  patients. materials...

background chronic obstructive pulmonary disease (copd) is a devastating disease.while there is no cure for copd and the lung damage associated with this disease cannot be reversed, it is still very important to diagnose it as early as possible. objectives in this paper, we propose a novel method based on the measurement of air trapping in the lungs from ct images to detect copd and to evaluate...

introduction: arterial gas derangement could change urinary sodium excretion in chronic obstructive pulmonary disease (copd) patients.there are very few and conflicting data in regards to the measurement of fractional excretion of sodium in copd patients. the main aim of this study was to assess the relationship between renal fractional excretion of sodium(fena) with arterial blood gas and spir...

the clinical copd questionnaire (ccq) has been developed to measure the health status of copd patients. the aim of this study was to translate ccq into the persian language and assess the validity and reliability of the translated version. we used a forward-backward procedure to translate the questionnaire. in a cross-sectional study 100 copd patients and 50 healthy subjects over 40 years old w...

abstract background: chronic obstructive pulmonary disease (copd) is currently the fourth cause of mortality worldwide. patients with copd experience periods of dyspnea, fatigue, and disability, which impact on their life. the objective of this study was to investigate the effect of short‑term inspiratory muscle training on exercise capacity, exertional dyspnea, and pulmonary lung function. mat...
