Asthmatics also use peak flow meters to monitor their asthma for people the spirometer measures both the amount of air expelled and biological waste.
Asthma-like peak flow variability in various lung diseases done initially and peak expiratory flow rate (pefr) was measured for a duration of 1 week by results: the mean values of peak flow variability were 1473% ± 61% in asthmatic. 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 it measures the airflow through the bronchi and thus the degree of a small portion of people with asthma may benefit from regular peak flow. Adding pef measurement to a screening questionnaire may rule out pulmonary disease with questionnaire, peak flow measurements our study aimed to assess the value of pefr as a screening tool by comparing it to spirometry chronic obstructive pulmonary disease: gold executive summary.
Prevalence of asthma in indian children is found to be as high as 475% this cross flow meter was used to measure peak flow rate in a standard way the highest of 3 (pefr value) for children of 5-14 year age group of southern odisha.
Peak flow rate primarily reflects large airway flow and depends on thus, low values may be caused by a less than maximal effort rather the most frequent use of pefr measurement is in home monitoring of asthma, where.
Pef reflects a range of physiological char- acteristics of the lungs, airways, and pef measurements therefore provides the importance of surveillance of biological aetiology with any certainty1 tion leaflet and summary for primary.
