for better management of asthma it is essential that patients adjust their treatment according to the medical plan developed by the health care professionals. to achieve this goal, patients should assess the severity of their disease regularly. the purpose of this study was to determine the effect of regular measurement of peak expiratory flow and patient education on self management of asthma....

in the management and evaluation of asthma, simple instruments for measurements of peak expiratory flow rate (pefr) are necessary. the aim of this study was to determine normal pefr of the healthy children in babol, iran. this study was randomly done on 1050 students (primary and secondary schools) in babol. mini-wright peak flow meter was used for measurement of pefr. the range of age, weight ...

background: measuring peak expiratory flow rate has been suggested as an important tool in asthma management by all international guidelines.   objective: studies on various populations have shown considerable variations in normal values of peak expiratory flow rate. since reference standards for iranian children are not available, the present study was performed to establish these standards.  ...

conclusions negative pressure inspiration is significantly impaired by an unstable chest wall. restoring mechanical stability of the fractured ribs improves respiratory outcomes similar to baseline values. results a wide variation in the mean inspiratory volumes and peak flows were measured between specimens; however, the effect of a flail chest wall and the subsequent internal fixation of the ...

more than one percent of the labor force in each country consists of welders exposed to various damages caused by welding. the number of studies conducted in this field is low, especially in iran. in this paper, we tried to discover any temporary and reversible obstructive effect of welding fumes on the respiratory systems of welders. in this cross-sectional study, peak expiratory flow rates an...

introduction: ramadan is the 9th  islamic lunar month during which muslims avoid eating and drinking from sunrise to sunset.  the effect of ramadan intermittent fasting on asthma control is controversial.  the aim of this study was to investigate the effects of ramadan fasting on the spirometric variables and clinical symptoms on well-controlled asthmatic patients during ramadan. material and m...
