Peak expiratory flow rate (PEFR) variability follows a specific pattern in asthmatics as well as in healthy individuals. There is scarcity of data for Indian healthy subjects. The PEFR (L/min.) was measured with Wright's portable peak flow meter at 05:00, 8:00, 11:00, 14:00, 17:00, 20:00 and 23:00 hours in 42 healthy, non-smoking adults of age group between 18-26 years. The variability of PEFR ...

Forty-six patients, known to suffer from asthma, attending an inner-city accident and emergency (A&E) department, were screened for the presence of chronic symptoms and their current treatment documented. The patients were asked if they knew their optimum peak expiratory flow rate (PEFR) or if they possessed a peak flow meter. The treatment being used by each of the 26 patients with evidence of...

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.  ...
