Abstract
Objective This study aims to compare peak expiratory flow mea-surement by peak flow meter and electronic spirometer in healthy
elementary school children.
Methods This was a cross-sectional study performed in an el-
ementary school near Cipto Mangunkusumo hospital (SDN
Pegangsaan 01). The study group consisted of healthy children
aged 6-12 year old. Data regarding identity and history of illness
was taken in each subject. Routine physical examination was per-
formed and recorded. Each subject performed lung function tests
by means of electronic spirometer AS-7 as well as by Mini-Wright
peak flow meter. The subject should perform a minimum of three
maneuvers for each method where only the best result was re-
corded. Method comparison test to assess agreement between
two methods was employed in this study.
Results There were 10 males and 15 females enrolled in this study.
None of the subjects currently have any respiratory symptoms and
signs. This study found that the mean peak expiratory flow (PEF) by
spirometer was 226.8±73.13 L/min while by peak flow meter was
223.0±45.05. Mean difference between spirometer and peak flow
meter measurements is 6.2 with standard deviation of 60.82. These
values resulted in limits of agreement of -115.44 to +127.84 L/min.
Conclusions This study finds disagreement between electronic
spirometer and Mini-Wright peak flow meter in measuring peak
expiratory flow, therefore these two devices cannot be used
interchangeably. Mini-Wright peak flow meter still has a role in
home monitoring, but the physician should interpret the results
carefully.
