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...
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...
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...
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...
The purpose of this study was to examine whether the resistance of the peak flow meter influences its recordings. One hundred and twelve subjects, (healthy nonsmokers and smokers and subjects with lung diseases) performed three or more peak expiratory flow (PEF) manoeuvres through a Fleisch pneumotachograph with and without a mini-Wright peak flow meter added in random order as a resistance in ...
Background & Aims: The purpose of the present study was to evaluate the effect of 8 weeks specific aquatic therapy on kyphosis angle and some pulmonary indices in male university students with kyphosis. Methods: A total of 15 males with increased normal thoracic Kyphosis (kyphosis 40 degrees, 20.70 ± 0.705 years old, height 175.5 ± 6.19 cm, weight 64.19 ± 8.23 kg) were selected. Before and afte...
The use of peak flow meters has been widely adopted for monitoring patients with asthma. The Working Party of the European Respiratory Society (ERS) has solely addressed technical and physiological issues relating to peak expiratory flow (PEF) (flow describes the rate of change of volume (volume rate), so that flow rate is equivalent to volume acceleration. Hence, PEF should be used in preferen...
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...
