Peak expiratory flow monitoring in asthmatic children.
OBJECTIVE To correlate forced expiratory volume in 1 second (VEF(1)) and peak expiratory flow (PEF) with clinical parameters in children with moderate and severe asthma. METHODS This was a non-concurrent cohort study, carried out at a pediatric pneumology clinic, in Belo Horizonte, MG, Brazil, between March and October 2002. The study enrolled children aged 5 to 16 years, with persistent asth...
متن کاملPeak 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 کاملPeak expiratory flow (PEF) monitoring.
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...
متن کاملThe influence of breathhold on peak expiratory flow in normal and asthmatic children.
We have previously demonstrated a 10% reduction in peak expiratory flow (PEF) in healthy adults following a breathhold at total lung capacity (TLC). This fall was attributed to dissipation of airway wall viscoelasticity, increasing airway wall compliance (Caw). To investigate this phenomenon in children and to determine whether the effect of breathhold would be greater in asthmatics than in nor...
متن کاملCan peak expiratory flow measurements estimate small airway function in asthmatic children?
BACKGROUND Asthma is characterized in part by small airways dysfunction. Peak expiratory flow (PEF) measurement has been suggested by all international guidelines as an important tool in asthma management. The correlation between PEF and FEV(1) but not with forced expired flow at 50% of vital capacity (FEF(50)) is well-established. STUDY OBJECTIVE To determine the value of PEF measurement as ...
