The Whistle Watch is a peak flow meter designed to enable asthmatic children to check their respiratory status. Children are old enough to use WhistleWatch as soon as they can make it whistle. When set to 80% of the patient's best PEFR (Peak Efficiency Flow Rate) by a doctor or clinici...
BACKGROUND: Self-monitoring of symptoms or peak flow monitoring (PFM) is recommended for all asthma patients and is commonly included in asthma management plans. Limited data are available documenting PFM outcomes in school settings. METHOD: Three hundred twenty-three urban children with persistent ...
A Study was undertaken to establish the normal values of peak flow rate using Wright peak flowmeter at several Japanese chest clinics and laboratories. The subjects were 417 healthy children aged 6 to 15 years. Prediction equations and regression lines are presented for each sex. The predicted val...

Peak Flow Meters The peak expiratory flow (PEF), also called peak expiratory flow rate (PEFR) is a person's maximum speed of expiration, as measured with a peak flow meter, a small, hand-held device used to monitor a person's ability to breathe out air. PF120A for Adults Peak ...
Acute effects of Asian dust events on respiratory symptoms and peak expiratory flow in children with mild asthma. Randomized Trial of Interventions to Improve Childhood Asthma in Homes with Wood-burning Stoves Compared to a spirometer, the resistance of this flow meter causes less variability in meas...
In spite of the disease severity in adult populations and the age of children, the lowest generated PIFR values were within the range producing adequate performance of Pulvinal DPI (>20 L/min). We conclude that inspiratory flow rates generated through the Pulvinal inhaler can be adequate in ...
In this study, the relation between these agents and peak expiratory flow (PEF) variability was investigated in 148 children (7 to 11 years of age) from the Netherlands, of whom 50% had self- or parent-reported chronic respiratory...

National guidelines for the treatment of asthma call for measures of peak expiratory flow rate as a valid and reproducible measure of airway obstruction and a guide for treatment plans. They are infrequently done in the ED setting and a 2004 study showed that only 64% of children eligible for...
