Peak Expiratory Flow Rate in Healthy Children from Tehran
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. Me...
متن کاملAudit of quality of diagnostic procedures for occupational asthma.
BACKGROUND Previous studies have reported deficiencies in the quality of the diagnosis of occupational asthma. A low quality of diagnostic procedures means that the occupational cause of asthma is less likely to be revealed. AIMS To assess the current quality of the diagnosis of occupational asthma before referral to a specialist occupational medicine centre. METHODS The quality of diagnost...
متن کاملImproving the quality of peak flow measurements for the diagnosis of occupational asthma.
INTRODUCTION Serial measurements of peak expiratory flow (PEF) are recommended in the evidence-based review list as the first stage in objective confirmation of occupational asthma. Different centres have reported widely different success in obtaining records of sufficient data quantity for diagnosis. We investigated different methods of instruction and determined the return rate and quality of...
متن کاملSerial measurements of peak expiratory flow and responsiveness to methacholine in the diagnosis of aluminium potroom asthma.
BACKGROUND Obstructive airways disease in aluminium potroom workers has been recognised for over 50 years. There is still controversy about whether this is true occupational asthma. METHODS A cross sectional survey of 379 potroom workers identified 26 subjects with symptoms suggestive of occupational asthma. Of these 26, 14 were considered by the plant physician to have occupational asthma an...
متن کاملDevelopment of an expert system for the interpretation of serial peak expiratory flow measurements in the diagnosis of occupational asthma
If asthma is due to work exposures there must be a relation between these exposures and the asthma. Asthma causes airway hyperresponsiveness and obstruction; the obstruction can be measured with portable meters, which usually measure peak expiratory flow, or sometimes forced expiratory volume in 1 second (FEV1). These can be measured serially (for instance 2 hourly) over several weeks at and aw...
