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...
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...
T he Wright peak expiratory flow meter was introduced in 1959 and provided a portable piece of equipment for assessing some aspects of lung function in the ambulatory care setting. The original device has been supplanted by the mini Wright peak flow meter (and a range of other devices) which have become relatively cheap but are reasonably reliable for home monitoring. So, with an available devi...
Although home recording of peak expiratory flow (PEF) is considered useful in managing asthma, little is known about the relationship of PEF variation to other indicators of disease activity. We examined the relationship of PEF variation, expressed in various ways, to symptoms, atopy, level of lung function, and airways hyperresponsiveness in schoolchildren with asthma. One hundred and two asth...
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....
Guidelines for asthma management advocate home peak expiratory flow (PEF) monitoring. It is commonly stated that PEF variability is a good proxy of bronchial hyperresponsiveness (BHR), a hallmark of asthma. However, this has hardly been tested longitudinally, as required to monitor asthma. This study assesses which PEF index correlates best with BHR longitudinally and whether the correlation im...
The aim of the study was to investigate the difference between encouraged self-recorded peak expiratory flow (PEF) with unobserved readings and to investigate any long-term changes in PEF self-recording. Patients were trained in the PEF technique and asked to keep 2-hourly PEF records until the next clinic visit. The patients PEF were then rechecked at the second clinic visit by a series of two...
Standardization of conditions for peak expiratory flow (PEF) monitoring is much more difficult in practice than for laboratory spirometry. Patients are usually asked to record PEF before medication. The aim of this study was to determine the effect of prior bronchodilator use on PEF outcome measures in a clinical trial. Electronic PEF records from 43 subjects with poorly controlled asthma were ...
Serial peak expiratory flow (PEF) assessment has been proposed in the clinical evaluation of asthma. In subjects attending the asthma clinic of a tertiary care hospital, we wanted to assess: 1) compliance in performing PEF; and 2) accuracy of a PEF-diary. Twenty adult asthmatic subjects, all using inhaled steroids, were asked to assess their PEF in the morning and evening with a VMX instrument ...
