Introduction: Pulmonary function test is a non-invasive test. It is measured by the spirometer and it gives an idea about the lung volume, lung capacities, rates of flow and gas exchange. Breathing exercise can increase lung function. The commonly performed breathing exercises are blowing bubbles, blow out whistle, pinwheels, Hoberman spheres etc. The aim of this study is to estimate lung function among healthy and blow out whistle beginners. Materials and methods: 60 Dental students consisting of 2 groups were involved in this study. Group 1: Control individuals (30). Group 2 individuals: blow out whistle beginners (30). Standardised RMS Helios spirometer was used. Age of 18-22, Healthy individuals and non-smokers were included in this study and smokers, alcoholic individuals, respiratory disorder individuals and post- COVID individuals were excluded from the study. Data was collected and analysed using paired ‘t’ tests. Significance is considered at P<0.05 level. Results: In this study FVC, FEV1, FEV3 were found to be significant and FEV1/FVC, FEF 25-75, PEFR were found to be insignificant. The post test values of FVC and FEV1 are comparatively higher than the pre test values. The pre test values of FEF 25-75 and  FEV3 are comparatively higher than the post test values. Conclusion: When this blow out exercise is performed there was a significant difference between healthy individuals and blow out whistle beginners. Significant increase in lung function is found. This recreational activity increases lung function which can be a preventive for many pulmonary diseases.

Objectives: Hajj is the world’s largest gathering to Makkah, Saudi Arabia. Wearing cotton made Ihram is a basic and an essential component of Hajj. The aim of this study was to investigate the lung functions among Hajj pilgrims who were wearing cotton towel ihram (ihram with fibers) compared to those who were wearing plain cotton ihram (ihram without fibers). Methods: Ninety male, non-smoker, Hajj pilgrim volunteers with age ranged 20-60 years were selected. Forty five of them wore cotton towel ihram and 45 wore plain ihram. A day before leaving for Hajj and wearing ihram (6th Dhu-al-Hijjah) lung function base line parameters of Hajj pilgrims were determined. Hajj Pilgrims continuously wear ihram from 7-10th Dhu-al-Hijjah. In the afternoon of 10th Dhu-al-Hijjah, after removal of ihram, all parameters were repeated and at the completion of Hajj when all pilgrims return to their homes at Riyadh, all parameters were recorded again. Results: Before wearing Ihram, anthropometric and lung function baseline parameters were recorded, no significant difference was found between the study population. After wearing Ihram on the 7th Dhu-al-Hijjah and its removal on the 10th Dhu-al-Hijjah significant decline in the lung function test parameters was observed among Hajj pilgrims who were wearing cotton towel ihram. Forced Vital Capacity (FVC) 4.30±1.18 vs. 5.03±1.41 (p=0.01); Forced Expiratory Flow 25% (FEF-25%) 4.39±1.94 vs. 5.69±2.84 (p=0.03); Forced Expiratory Flow-50% (FEF-50%) 2.93±1.65 vs. 4.07±2.08 (p=0.01); Forced Expiratory Flow-75% (FEF-75%) 1.02±0.70 vs. 1.66±0.94 (p=0.002) compared to those who were wearing plain ihram. Conclusions: Lung function test parameters were decreased among the Hajj pilgrims who were wearing cotton towel ihram compared to those who were wearing plain cotton ihram. The pattern of impairment of lung function shows an obstructive peripheral airway lung involvement. It is suggested to conduct further large sample size studies to confirm the present study observations and reach at better conclusions. doi: https://doi.org/10.12669/pjms.35.4.727 How to cite this:Meo SA, Iqbal M, Usmani AM, Almana AA, Alrashed AH, Al-Regaiey KA.

Background: Box breathing exercise is a technique of slow breathing rhythm also known as square breathing used universally. It increases the performance and concentration level, it also acts as a powerful stress relief. It is tested with a spirometer for the lung function test that measures the airflow of the upper and lower respiratory tract. This method builds up carbon dioxide in blood which calms down and regulates the ANS (Autonomic Nervous System), which enhances the cardio- inhibitory response of the vagus nerve that improves the mood. The main aim of the study was to analyze the effect of box breathing technique on lung function Materials and Methods: The present study was carried out among the participants at the age of 18-25 years from Saveetha Dental College. A total of 30 participants were included in this study (15 males, 15 females). The experimental training procedures consisted of 2 sessions of box breathing day and night for a period of 30 days. Participants were informed of the procedures of the box breathing technique. RMS Helios spirometer was used to measure lung volumes and capacities. Statistics analysis was done using SPSS software, paired t test. P value of less than or equal to 0.05 was considered significant statistically. Results: There was a significant increase among the participants FVC (Forced Vital Capacity), FEV1 (Forced Expiratory Volume), FIVC (Forced Inspiratory Vital Capacity) parameters after 2 sessions on each day of box breathing technique for a period of 30 days. Other parameters increased to 10% but not significantly. Conclusion: The present study illustrates the potential for box breathing practice to improve lung performance and reduce stress in healthy individuals. Despite the significant difference in FVC, FEV, FIVC levels supporting improved lung function, further investigation is needed to delineate mechanisms that underlie these benefits

Expiratory Flow

Background: Asthma remain the most common chronic inflammatory lung disease in childhood. Asthma management needs lung function assessment. Peak Expiratory Flow Rate (PEFR) is one of the lung function test. PEFR has been used as measure of ventilatory capacity for long mainly because of a simple, less tiring procedure than other lung function test. It is easy to use, inexpensive, portable, reliable can be used by patients, parents, home & clinic. There is no national nomogram on PEFR in Bangladesh. We always use the nomogram of other countries for diagnosis, management of Asthma. This study was taken to establish what is the normal pattern of PEFR in Bangladeshi children of rural and urban area and to construct nomogram of PEFR in healthy Bangladeshi children. Materials and methods : It is a cross sectional study conducted in different 6 schools (Urban & rural) in Chattogram District of both sexes (5-15 yrs old) in equal proportion of child. Study period was from April 2009 to November 2009 under supervision of Pediatrics Department of Chattogram Medical College. Sample was selected by non-probability technique. Data were collected by pretested questionnaire including exclusion criteria. Results: A total of 1424 healthy school children (Age 5-15 yrs) of equal sexes of both rural and urban school were included during study. The best of three PEFR of boys ranged from 90 to 750 I/min (Mean 291 I/min, SD 143) and in case of girls ranged from 80 to 540 (L/min (mean 236 L/min, SD 94.38). The positive correlation of PEFR with various anthrometric parameters specially height and observed difference with boys and girls. The most significant correlation was observed PEFR with height and also found different value of PEFR between rural and urban children. Conclusion : This study concluded that there is significant difference of PEFR between Bangladeshi boys and girls (5-15 yrs). Height is the best predictor of PEFR value than any other anthrometric parameters PEFR value of Bangladeshi Girls is lower than that of Boys and significant difference between PEFR values among urban & rural Bangladeshi children.

Abstract Introduction Patients affected by esophageal atresia (EA) often faced airway problems, due to multifactorial dynamics (tracheomalacia, gastroesophageal reflex disorder, etc.). The aim of this study was to longitudinally evaluate the lung function test (LFT) in those infants to explore how the LFT modifies at mid-term follow-up. Methods Retrospective evaluation of lung functions in infants treated for EA (2010–2017) was performed at three time points: 6 months, 12 months, and 24 months. Tidal volume (Vt), respiratory rate (RR), and time to peak tidal expiratory flow as a percentage of total expiratory time (tPTEF/te) were analyzed. ANOVA test was used as appropriate. Results During the study period 172 patients were treated for EA. Of those 50 infants (28%) underwent LFT at 6 months, 30 at 12 months, and 11 at 24 months. Tracheomalacia was present in 20 infants (42%). Both Vt (6,79 ml/kg vs 7,82 ml/kg vs 8,37 ml/kg—p = 0,001) and RR (49,7 a/min vs 40,6 a/min vs 34,0 a/min—p = 0,020) significantly improved, while there was no significant difference for tPTEF/te (0,25 vs 0,26 vs 0,29—p = 0,62) despite the data showing an improvement trend. Conclusion The preliminary data suggest that, although EA patients may present impaired LTF in early infancy, lung function seems to improve over time, showing normal pulmonary function test at 24 months. The presence of selection bias and the retrospective nature of the study limit our result. Nonetheless, evaluation of lung function is warranted in EA infants to early detect respiratory symptoms, ideally reducing the impact on short- and long-term pulmonary outcomes.

Introduction: The adverse health effects of air pollution have been observed in many epidemiological studies. The aim of this research was to study the effects of air pollution on pulmonary functions in schoolchildren in Tehran city. Materials and methods: Total number of 167 schoolchildren were selected to participate in this study. Data were analyzed using analysis of variance (ANOVA) and generalized estimating equation (GEE) to determine the relationship of air pollution and lung function tests. Results: The result of this study showed that there are statistically significant differences in value of air pollution between areas. The results present that concentration of O3, PM10, NO2 has a negative association with lung function tests but concentration of CO, PM2.5, and SO2 had no association with decreased lung function tests. Time variable of air pollution was not statistically significant effect on lung function test. Conclusion: In this study, we conclude that air pollution in Tehran city can be decreased lung function test indexes that may be affected by short-time exposure to air pollutant.

Background:Interstitial lung disease (ILD) in inflammatory rheumatic diseases (IRD) is associated with increased mortality. Moreover, the lung is one of the most effected organs on IRD. Consequently, screening methods were required to the detect ILD in IRD.Objectives:The objective of the following study is to evaluate the diagnostic value of lung function test, chest x-ray and HR-CT of the lung in the detection of ILD at the onset of IRD.Methods:The study is designed as a case-control study and includes 126 patients with a newly diagnosed IRD. It was matched by gender, age and the performance of lung function test and chest x-ray. The sensitivity and specificity were verified by crosstabs and receiver operating characteristic (ROC) curve analysis. The study cohort was divided in two groups (ILD group: n = 63 and control group: n = 63). If possible, all patients received a lung function test and optional a chest x-ray. Patients with pathological findings in the screening tests (chest x-ray or reduced diffusing capacity for carbon monoxide (DLCO) < 80 %) maintained a high-resolution computer tomography (HR-CT) of the lung. Additionally, an immunological bronchioalveolar lavage was performed in the ILD group as gold standard for the detection of ILD.Results:The DLCO (< 80 %) revealed a sensitivity of 83.6 % and specificity of 45.8 % for the detection of ILD. Other examined parameter of lung function test showed no sufficient sensitivity as screening test (FVC = Forced Vital Capacity, FEV1 = Forced Expiratory Volume in 1 second, TLC = Total Lung Capacity, TLCO = Transfer factor of the Lung for carbon monoxide). Also, a combination of different parameter did not increase the sensitivity. The sensitivity and specificity of chest x-ray for the verification of ILD was 64.2 % versus 73.6 %. The combination of DLCO (< 80 %) and chest x-ray showed a sensitivity with 95.2 % and specificity with 38.7 %. The highest sensitivity (95.2 %) and specificity (77.4 %) was observed for the combination of DLCO (< 80 %) and HR-CT of the lung.Conclusion:The study highlighted that a reduced DLCO in lung function test is associated with a lung involvement in IRD. DLCO represented a potential screening parameter for lung manifestation in IRD. Especially patients with suspected vasculitis should receive an additional chest x-ray. Based on the high sensitivity of DLCO in combination with chest x-ray or HR-CT for the detection of ILD in IRD, all patients with a reduced DLCO (< 80%) should obtained an imaging of the lung.Disclosure of Interests:None declared

Examination Stress

Background: Professional degrees are daunting to the learning group because of a modern curriculum that is dramatically different from high school curricula and other educational courses. It is more pronounced among first year students in educational institutions because of rivalry and demands from institution managers, academic staff and parents. Stress causes many detrimental effects in the body. Aim: The present study planned to evaluate the effect of examination stress on the changes in lung functions among dental college students. Materials and Methods: 20 normal students were selected and categorised into normal and stressed students. They were assessed for a lung function test using RMS helios 702 Spirometer. The parameters such as FVC, FEV1, FEV1/FVC, PEFR, FEF25-75 were assessed. Results: It is observed that there was a decrease in the values of FVC, FEV1, FEV1/FVC, PEFR, FEF25-75 in exam stressed students when compared to normal students. The values of FEV1/FVC and FEF25-75 were statistically significant. Conclusion: Thus, the study concluded an innovative finding that there was an inverse association with depressive symptoms in the pulmonary function test of exam stressed students which was shown by a statistically significant decrease in FEV1/FVC and FEF25-75. Exam is really a stressful experience and affects both male and female students. Awareness should be conducted among students about ill effects of stress. Decreased stress, increased lung function results in increased academic performance.
