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.

ABSTRACT Peak expiratory flow rate (PEFR) is a simple, reliable, and easily reproducible and measurable lung function test. It has not been formally assessed whether the PEFR values measured with peak flow meter are in close correlation with the values measured by digital spirometer. The present study is carried out to determine whether there is a significant difference between the PEFR values derived from digital spirometer and peak flow meter in patients with respiratory symptoms.

Predicted Values

Peak Expiratory Flow Rate (PEF) is a simple and reproducible indicator of ventilatory function.1 It is the maximal airflow sustained for at least 10 msec during a forced expiration after deep inspiration. PEF is easy to measure with the Wright Peak Flow Minimeter. Results from this simple lightweight instrument correlate well with those from the older, bigger model.2 Predicted values vary with age, sex and height in adults;3,4 in children they are related to height alone.4,5 It is usual to record the best of three readings.

Ventilatory Lung Function

Peak expiratory flow rate (PEFR) is the maximal expiratory flow rate sustained by a subject for at least 10 milliseconds expressed in Litre per minute (L/min). PEFR is a simple, reliable, reproducible and easily measurable ventilatory lung function test. This simple test had been measured by various types and shapes of instruments for long since, now mini- Wright peak flow meter is widely used to measure the of PEFR values. Mini-Wright peak flow meter is cheap, easily portable and reproducible device for PEFR even below the age 5 years. Different countries use their own nomogram or prediction equation to find out mean PEFR values of particular height. Similarly, the prediction equation for calculation of PEFR values of Bangladeshi boys and girls are 5.96XHeight-495 and 5.70XHeight-479 respectively. Peak expiratory flow rate is very useful tool for diagnosis, management and follow up of reversible airway diseases.

Background: Peak expiratory flow rate is the simplest , cost effective and easily available test to assess the respiratory function. PEFR is measured by a peak expiratory flow meter. Measurement of PEFR is most commonly used for asthmatic patients. To evaluate the effect of lower respiratory tract infection on peak expiratory flow rate in children. Methods: PEFR were measured in eighty children suffering from LRTI by peak flow meter . Height and weight were measured. PEFR was compared with the normal charts. mean PEFR was calculated and predicted percentage of PEFR was calculated.Results: Mean PEFR in pneumonia , para pneumonic effusion, bronchiectasis, and bronchitis was 187.2 , 187.6, 171.85 and 173.1 respectively. Mean PEFR was maximally reduced in bronchiectasis and bronchitis. Mean  PEFR was reduced in female children in comparison to males with LRTI. PEFR was decreased  more in children with severe clinical presentation and with malnutrition.Conclusions: In this study , most common LRTI was pneumonia followed by parapneumonic effusion. PEFR was maximally reduced in bronchiectasis and bronchitis. Undernourished children were more affected.
