Objective This study aims to compare peak expiratory flow mea-surement by peak flow meter and electronic spirometer in healthyelementary school children.Methods This was a cross-sectional study performed in an el-ementary school near Cipto Mangunkusumo hospital (SDNPegangsaan 01). The study group consisted of healthy childrenaged 6-12 year old. Data regarding identity and history of illnesswas taken in each subject. Routine physical examination was per-formed and recorded. Each subject performed lung function testsby means of electronic spirometer AS-7 as well as by Mini-Wrightpeak flow meter. The subject should perform a minimum of threemaneuvers for each method where only the best result was re-corded. Method comparison test to assess agreement betweentwo 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 andsigns. This study found that the mean peak expiratory flow (PEF) byspirometer was 226.8±73.13 L/min while by peak flow meter was223.0±45.05. Mean difference between spirometer and peak flowmeter measurements is 6.2 with standard deviation of 60.82. Thesevalues resulted in limits of agreement of -115.44 to +127.84 L/min.Conclusions This study finds disagreement between electronicspirometer and Mini-Wright peak flow meter in measuring peakexpiratory flow, therefore these two devices cannot be usedinterchangeably. Mini-Wright peak flow meter still has a role inhome monitoring, but the physician should interpret the resultscarefully.

Background: In this era of globalization one of the growing industries is the construction industry and there are various occupational problems faced by the workers especially in Asian countries mostly in India; the problems are related to both physical and mental health. All the construction sites generate high concentration of dust particles from cement, silica, asbestos, concrete, wood, stand and stand that causes respiratory problems in the workers. PEFR is the maximum air that is generated after forceful expiration, after full lung inspiration. So if there is any accumulation of dust particles the PEFR decreases as the elasticity of lungs to recoil is distrusted due to the lodged particles. Material and Method: A descriptive observation study was carried out on 50 building construction workers. The purpose of the study was explained and informed consent was taken. The PEFR was measured using peak expiratory flow meter. The data was analyzed using standard statistical software. Result: The procedure of using peak flow meter that was carried out for 3 times and the highest value from the three was considered as peak flow rate, using statistical method mean and standard deviation were calculated. The mean of Peak Expiratory Flow Rate is 321.1 L/min. Conclusion: This study concluded that the peak expiratory flow rate is reduced in building construction workers those who are working for than 2 years on the construction sites. Key words: construction workers, occupation diseases, PEFR, peak expiratory flow meter.

Home-monitoring of peak expiratory flow rate using the mini-Wright peak flow meter is a useful technique for determining whether or not unexplained respiratory symptoms are caused by asthma. It is of particular value when airflow obstruction cannot be demonstrated at the time of consultation.

Expiratory Flow

Background: Peak Expiratory Flow (PEF) is a value test for lung function and can be conveniently measured by using relatively inexpensive and portable Peak Flow Meter, identifying and assessing the degree of airflow limitation of individuals. While PEFR is obviously related to factors like age, weight, height, race, gender, it may also be additionally affected by seasons and climate. The purpose of study being to observe seasonal variation in PEFR amongst school going children and to observe peak expiratory flow rate in school going children in urban and rural areas.Methods: This prospective and comparative study was carried out on total 600 children; with 300 each from rural and urban schools, of age group 10-14 years, both sexes. Peak expiratory flow meter was used for the measurements in the seasons of summer (April to June) and winter (December to February) of the year. The results thus obtained were compiled and analysed.Results: The mean PEFR value (Litres/min) during summers in the rural children was 243.50(S.D.=16.050) while during winters was 253.63(S.D.=16.934), highly significant (p<0.001);  mean PEFR summers in the urban  children was 241.50(S.D.=20.530)and during winters  was 249.93(S.D.=21.685), again highly significant (p<0.001).In both rural and urban groups PEFR values increased with increase in height and weight of the children which was found to be highly significant (p<0.001). Girls representation proportion in rural vs urban schools being 49% vs 45%; whereas boys being 51% vs 55% respectively.Conclusions: Peak expiratory flow rate decreased during summer season of the year in both rural and urban school attending children. In both the groups PEFR values had a direct correlation with height and weight of the children. Rural schools showed more girl student representation than their urban counterparts indicating more awareness for girl child education amongst rural population.
