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

Background: Obesity is a chronic disease characterized by excessive body fat that causes damage to the individual’s health and is associated with comorbidities such as diabetes and hypertension and vascular dysfunction. This cross-sectional study was carried out with the objective of evaluating the effect of obesity on lung function test in obese but otherwise healthy adults.Methods: It was a cross-sectional study carried out at tertiary care institute of Gujarat, India. It was conducted over a period of 5 months. A total of 240 adult healthy subjects of both sexes were selected randomly belonging to varying socio-economic status. The study subjects were divided into 3 categories (normal body mass index i.e. BMI, overweight, obese). BMI were calculated for the randomly selected subjects from each list till the desired number in each BMI group were attained. Four respiratory parameters viz. forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1), forced expiratory volume in 3 seconds (FEV3), and maximum voluntary ventilation (MVV) were used to assess their lung functions.Results: Two hundred and forty subjects (each group having n=80). The mean age of group I, group II and group III were 27.45±6.37, 28.18±6.42 and 28.98±6.74 respectively. Lung volumes showed significant difference in relation to the BMI. FVC and FEV1 show significant decrease. Group III verses group I (p˂0.001 and p˂0.017 respectively) FEV3 showed significant difference between group I and group III and between group II and group III (p˂0.001). MVV was significantly lower in group III when compared to group I.Conclusions: There is decline in pulmonary function in obese as compared to normal weight adults. These findings suggest deleterious effects on ventilatory mechanics caused by obesity, due to probable lung compression (reduction in the expiratory reserve volume i.e. ERV), leading to a compensatory increase in the inspiratory reserve volume (IRV) in an attempt to maintain a constant vital capacity (VC).

Background: Spirometry is an essential tool to evaluate lung function of health and disease. Adaptability of lung and chest among athletes can be assessed by lung function test (LFT). The quest of our study was to evaluate the lung function (LF) of highly trained Indian female weighting athletes, and intended to appraise the adaptation of LF among trained elite athletes.Methods: Top ranked Indian female professional weightlifters (study group, n=6) were recruited for this study. Three out of the six weightlifters were from top ten world ranking of 6th, 7th and 9th. Age matched controls (control group, n=6) were selected for this study. Maximum voluntary ventilation (MVV), vital capacity (VC), forced vital capacity (FVC), percentage of forced expiratory volume in first second (FEV1%) and ratio of forced expiratory volume in first second and forced vital capacity (FEV1/FVC%) have been evaluated as per the ATS/ERS guidelines.Results: Statistically higher significant values of VC and FVC were noted in study group, where as other values (MVV, FEV1% and FEV1/FVC%) found no significant difference between two groups.Conclusions: Power, strength and explosiveness of the skeletal muscles are vital domains in weightlifting sport. Weightlifting is such a sport doesn’t require much ventilatory efforts during training as well as competition. This study clueing that physiological adaptation/ improvement of the pulmonary function (PF) depends on the type of the sport being engaged by the athletes.

In 415 nonsmoking asthmatic children who were seen consecutively, asthma symptoms were more severe if the mother was a smoker than if she was a nonsmoker. This applied to both sexes but was more marked in boys than in girls. There were also other indications that sons were the more severely affected: the forced expiratory volume at 1 second, the forced expiratory flow rate during the middle half of the forced vital capacity, and the provocation concentration of histamine needed to result in a 20% decrease in the forced expiratory volume at 1 second were significantly decreased only in the sons, and lung function test results were significantly less in sons than in daughters of mothers who smoked. When the 415 children were stratified according to age, lung function improved significantly with increasing age in the children of nonsmokers; in children of smokers, by contrast, symptoms and lung function test results became progressively worse. As well, there was a correlation between these indications of asthma severity and the number of years the child had been exposed to the mother's smoke. It appeared that, compared with girls, boys were more sensitive to passive smoking, and that its adverse effect increased with age and with duration of exposure.

Background: Chronic consumption of khat affects many organ systems and leads to various health disturbances in the chewers. Few studies examined the acute effects of khat ingestion on lung function parameters. However, studies which assessed the long-term effects of khat chewing on pulmonary function parameters and oxygen saturation are lacking. Objective: The aim of this study was to assess the impact of chronic Khat chewing on pulmonary function parameters and oxygen saturation among chronic Khat chewers in Wolkite, Ethiopia. Methods: A community-based comparative cross-sectional study was conducted in Wolkite, Ethiopia from 1 June 2018 to 15 August 2018. A total of 324 participants, 162 khat chewers and 162 non-chewers were included in the study. The data were collected through face-to-face interview by trained data collectors. British Medical Research Council respiratory questionnaire was used to assess respiratory symptoms. A spirometer was used to assess various lung function parameters. Moreover, oxygen saturation of hemoglobin was measured using pulse oximeter. Data were entered into CSPro version 6.2 and analyzed using SPSS version 23. Results: This study showed statistically significant (p < 0.05) reduction in the mean values of forced vital capacity, forced expiratory volume in first second and maximum ventilation volume among khat chewers as compared to non-chewers. There was no significant difference in the mean values of other lung function parameters between the two groups. Similarly, there was no significant difference (p = 0.642) in mean oxygen saturation of hemoglobin (SaO2) across the two groups. Conclusion: It is evident from this study that long-term khat consumption is associated with decreased mean forced vital capacity, forced expiratory volume in first second and maximum ventilation volume. Hence, there is a need for further study to strengthen the current findings and to explore the mechanisms of khat chewing effect on lung function parameters.

Background Increased pulmonary blood flow may lead to abnormal lung function in children with left-to-right (L to R) shunt congenital heart disease. This condition has been linked to considerable mortality and morbidity, including reduced lung function. Objective To assess for lung function abnormality in children with L to R shunt congenital heart disease. Methods We conducted a cross-sectional study involving children aged 5-18 years and diagnosed with L to R shunt congenital heart disease at Dr. Sardjito Hospital from March to May 2017. Subjects underwent spirometry tests to measure forced expiratory volume-1 (FEV-1), forced vital capacity (FVC), and forced expiratory volume-1 (FEV-1)/forced vital capacity (FVC). Results Of 61 eligible subjects, 30 (49.2%) children had atrial septal defect (ASD), 25 (41%) children had ventricular septal defect (VSD), and 6 (9.8%) children had patent ductus arteriosus (PDA). Spirometry revealed lung function abnormalities in 37 (60.7%) children. Restrictive lung function was documented in 21/37 children, obstructive lung function in 11/37 children, and mixed pattern of lung function abnormality in 5/37 children. Pulmonary hypertension was found in 21 children. There was no significant difference in lung function among children with and without pulmonary hypertension (P=0.072). Conclusion Abnormal lung function is prevalent in 60.7% of children with L to R shunt congenital heart disease, of which restrictive lung function is the most common. There was no significant difference in lung function among children with and without pulmonary hypertension.

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: 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.

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.
