Expiratory Flow

INTRODUCTION: Peak expiratory flow rate (PEFR) is commonly used to monitor the progression of respiratory diseases as it gives good information about the status of airways. A good amount of research is going across the world to establish a local prediction equation. The joint task force of the American thoracic society and European Respiratory Society has promoted research in this regard. In India, data derived from the Caucasian population are still used for PEFR. OBJECTIVE: To verify the relationship between PEF levels and the variables age, sex, anthropometric and body surface area, and establish the regression equation for young Indian adults. METHODS:  A cross-sectional observational study was conducted in 15-25 years aged 1000 subjects from the Metropolitan region of Mumbai. Pearson’s correlation coefficient was used to understand the relation of anthropometric parameters and PEFR. Multivariate regression analysis was done for establishing a prediction equation (Alpha 5%).  RESULTS: Age and all anthropometric parameters were correlated with PEFR. The mean PEFR of the male population was 515 ml/sec, whereas, for females, it was 399 ml/sec, for PEFR highest correlation was observed with BSA (.696) followed by weight (.667), height (.630), age (.504) whereas BMI shown lowest correlation coefficient (.445). PEFR had the best significance with age, BSA, Height, and BMI. It had less significance with weight. In females, PEFR had the best significance with Height, weight, BMI, and Age. CONCLUSION: Gender-wise differences exist in PEFR. Hence gender-specific equations are needed for the estimation of PEFR.

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.

Expiratory Flow

Introduction: In diagnosis and treatment of respiratory diseases, the assessment of lung functions is of considerable importance. So, normal reference values for pulmonary function tests of any population need to be assessed. Objective: An attempt has been made in the present study to measure the peak expiratory flow rate (PEFR) in healthy Nepalese children and young adults. Material and methods: One hundred ninety six (196) students were selected by inclusion criteria from different schools and colleges in Pokhara Sub- Metropolitan City, Nepal. The anthropometric measurements and peak expiratory flow rate (PEFR) were measured by standard procedures. Result: The mean PEFR values of males and females are found to have 350.3 (±135.0) l.min-1 and 280.2 (±98.77) l. min-1 respectively. The PEFR values of Nepalese males of the present study are found to be higher as compared to their females' counterparts. It is interestingly noted that at preadolescence time, PEFR is almost comparable in both sexes but after puberty males attained significantly higher values than females. The trend of PEFR values with development of the age is also been noted. It is interestingly pointed out that PEFR values of Nepalese males in the present study increases significantly with the advancement of age up to 20 years of age and then after PEFR do not change. On the other hand, females showed significant PEFR increment with the advancement of age up to 15 years of age only and then after PEFR do not improve significantly. Conclusion: PEFR was found to be influenced significantly by height not by the weight. Finally, a prediction equation was established by which PEFR of Nepalese population of 5 to 25 years of age can be estimated from age or height.

Background: The increasing number of overweight and obese individuals is a serious health problem worldwide. Growing evidence had clearly and consistently evidenced that obesity is an essential and direct predictor of respiratory function. Aim and objectives were to observe body mass index (BMI) based variations in respiratory parameter in overweight and obese individuals.  Methods: The study was carried out on 320 (18-28 years) subjects in district Dehradun of Uttarakhand, India. Different anthropometric parameters and respiratory parameter was measured by proper procedures.  Results: The anthropometric parameters weight and height were found statistically significant (p<0.05) among all subjects. BMI based and gender-based comparison of respiratory parameter were found statistically significant (p<0.05). The correlation of BMI with peak expiratory flow rate (PEFR) was found statistically very highly significant. The correlation coefficient (r) between BMI with PEFR was found= -0.6, denotes partial negative correlation.Conclusions: Our study concluded that with increased BMI the PEFR decreases, which signifies that there is broncho construction due to various mechanisms like direct action of adipose tissue on the air ways via a decrease in luminal diameter of the air way and an increase in the probability of airway collapse.
