introduction: chronic obstructive pulmonary disease (copd) patients are at increased risk of sleep-disorders. the concomitant occurrence of copd and obstructive sleep apnea hypopnea syndrome (osahs) is named overlap syndrome. this study aimed to evaluate the severity of osahs in overlap syndrome patients.materials & methods: this cross-sectional study was conducted on adult patients with forced...

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 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...

The six-minute walk test (6MWT) is a well-tolerated test which reflects daily activities and can be easily used in clinical practice. The 6MWT provides information about functional capacity, response to therapy and prognosis across a range of chronic cardiopulmonary conditions. Moreover, the 6MWT is sensitive to the common therapies used for chronic obstructive pulmonary disease, such as pulmon...

background: resistive inspiratory muscle training (rimt) is a well-known technique for rehabilitation of patients with chronic obstructive pulmonary disease (copd). incentive spirometry is another technique with potential viability for this application, but there is limited evidence in support of its efficacy in the rehabilitation of copd patients. aim: the objective of this study was to compar...

background: application noninvasive ventilation in the patients with exacerbation of chronic obstructive pulmonary disease (copd) reduced mortality. this case-control study was designed to compare efficiency and outcome of non-invasive (niv) versus invasive positive pressure ventilation (ippv) in respiratory failure due to copd methods: the patients were assigned to niv or ippv intermittantly.t...

conclusions the eccentric exercise therapy in the form of downhill walking had positive effects on functions and qol of studied case, especially had an augmenting effect on the thigh muscles size. case presentation the case was a 71- year-old woman suffering from chronic bronchitis and bronchiectasis for 30 years that has been faced with increased musculoskeletal disorders in recent months. the...
