The Relationship

Background- To date there are very few studies evaluating the relationship between sedentary behaviour and pulmonary function in a population who works for more than half a day i.e. 6-8hrs continuously in front of technologies (mainly desk jobs) with no sign of physical activities. Hence the aim of the study was to evaluate the effects of a sedentary lifestyle on peak expiratory flow rate. METHOD- The study was conducted on 75 desk job workers, males and females of age group 30-45 years working for 6-8 hours without physical activity. Analysis of their lung function capacity was done by PEFR. RESULT-It is seen that there is a significant difference in the predicted and obtained values of PEFR in both genders. The mean predicted value of PEFR in females is 416.04±25.72 and the mean obtained value of PEFR is 284.7±72.84. In males the mean predicted value of PEFR is 542.6±23.33 and the mean obtained value of PEFR is 396.2±80.6. It shows that the sedentary lifestyle with physical inactivity affects the PEFR values CONCLUSION-Regular exercise in terms of physical activity is essential for every individual with a sedentary lifestyle to overcome health problems and improve their pulmonary functions.

Background: Cigarette smoking has remained a popular habit since ages. Most people are well aware of the deleterious effects of cigarette smoking yet continue to give a blind eye which dete­riorates overall public health. The purpose of the present study was to assess Peak Expiratory Flow Rate among smoking and nonsmoking staffs who work in Kathmandu Medical College. Methods: In this comparative cross-sectional study Peak Expiratory Flow Rate was obtained using Mini Wright’s Peak Flow Meter of 108 smokers and 108 nonsmokers in the age group ranging from 25-45 years. Those who never smoked or who have quit smoking for the past 2 years were grouped as nonsmokers and the smokers with history of smoking at least five or more cigarettes per day for at least two years were included in the study for measuring their Peak Expiratory Flow Rate. Data was collected, compiled and analyzed by using Statistical Package of Social Science (SPSS) software version16. Student ‘t’ test was used for group comparison. Results: The Peak Expiratory Flow Rate value was significantly reduced in the smokers (p value< 0.05). Mean Peak Expiratory Flow Rate was reduced with increasing age of the smokers. However, no significant difference was observed in Peak Expiratory Flow Rate with increase in the number of cigarettes smoked (p value> 0.05). Conclusions: In the study Peak Expiratory Flow Rate among smokers (367.13 ± 74.182) was lower than nonsmokers (471.39±60.842), which was statistically significant proving that cigarette smok­ing reduced peak expiratory flow rate.

The Relationship

1. As marked lability of bronchial obstruction is a risk factor for asthma severity, it may influence dyspnoea, the most common subjective complaint in asthma. We therefore studied the relationship between spontaneous dyspnoea and the degree of bronchial lability, as assessed by the daily variability in peak expiratory flow rate and the bronchial responsiveness to either carbachol or salbutamol, in 33 stable symptomatic asthmatic patients. 2. Three times daily, for 10 consecutive days, the patients rated the intensity of their dyspnoea on a visual analogue scale and immediately afterwards recorded their peak expiratory flow rate. Within the next 5 days, we determined the bronchial response by measuring the forced expiratory volume in 1 s and the specific resistance of airways to either carbachol or salbutamol according to baseline airway obstruction. 3. We characterized dyspnoea for each patient by using two parameters: (1) the relationship with underlying airway obstruction, as assessed by the correlation coefficient r between dyspnoea scores and corresponding values of peak expiratory flow rate (r DSc-PEFR), and (2) the intensity, as assessed by the mean visual analogue scale dyspnoea score adjusted for comparable airway obstruction. Bronchial lability was characterized by (1) variability in mean daily peak expiratory flow rate and (2) bronchial responsiveness to either carbachol (as assessed by the threshold dose and the slope of the dose-response curve) or salbutamol (as assessed by the threshold dose and maximal response). We assessed the relationship between dyspnoea and bronchial lability by correlating each of their respective characteristics. 4. We found large inter-subject differences in both characteristics of dyspnoea, r DSc-PEFR was unrelated to variability in mean daily peak expiratory flow rate and to all characteristics of bronchial responsiveness used, except for maximal salbutamol-induced increase in forced expiratory volume in 1 s (as a percentage of predicted). Adjusted visual analogue scale dyspnoea scores were unrelated to all characteristics of bronchial lability. 5. Our results suggest that spontaneous dyspnoea, as characterized by its intensity at comparable levels of airway obstruction and by its relationship with underlying airway obstruction, is poorly related to the degree of bronchial lability in stable symptomatic asthmatic patients.

Abstract Objective: To explore the association of handgrip strength and peak expiratory flow rate with site-specific bone mineral density T scores, and to study the correlation of body mass index and physical activity with the three parameters. Methods: The cross-sectional study was conducted in November 2018 at the Combined Military Hospital, Lahore Medical College and Institute of Dentistry, Lahore, Pakistan, and comprised healthy young adults. Data was collected using the international physical activity questionnaire. The subjects were grouped into low, moderate and high categories. Handgrip strength, peak expiratory flow rate, bone mineral density T scores and body mass index were measured for each subject. Data was analysed using SPSS 24. Results: Of the 102 subjects, 52(50.9%) were males and 50(49%) were females. There was a significant difference between the median values for all parameters of males and females (p<0.05). Bone mineral density and physical activity were moderately associated with handgrip strength and peak expiratory flow rate (p<0.05). Body mass index showed a moderate association with bone mineral density (p<0.05). Conclusion: Healthy young adults with better respiratory function and handgrip strength were found to have higher values of site-specific calcaneal bone mineral density. Subjects with higher reported levels of physical activity and a higher body mass index within a healthy range presented with improved values of bone mineral density, handgrip strength and peak expiratory flow rate. Key Words: Bone mineral density, Handgrip strength, Peak expiratory flow rate, Body mass index, Physical activity. Continuous...

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.

AbstractIntroduction:Although the efficacy of the administration of beta-adrenergic bronchodilators has been demonstrated, the best method available for the delivery of these drugs in the prehospital setting has not been defined. This paper compares the effects of administration of metaproterenol when administered by paramedics using either a metered-dose inhaler (MDI) or a hand-held nebulizer (HHN).Hypothesis:There is no difference in the effects produced in patients suffering from smooth bronchiolar muscle spasm by metaproterenol when delivered either by a standard metered-dose inhaler or with a hand-held nebulizer.Participants:Consecutive prehospital patients complaining of difficulty breathing with clinical evidence of bronchospasm and with a history of asthma, chronic obstructive pulmonary disease, or emphysema who were not in extremis.Methods:Prior to the administration of metaproterenol, a peak expiratory flow rate (PEFR) was obtained. This measurement was repeated five minutes following the conclusion of the administration of metaproterenol. Patients in Burbank, California, received the treatment using a standard metered-dose inhaler, and those in Madison, Wisconsin, received the drug using a hand-held nebulizer. Peak expiratory flow rates were compared using Student's t-tests with Bonferroni's correction. Statistical significance was set at p <0.05.Results:Data were collected from 36 consecutive patients by the paramedics of the Burbank Fire Department and from 32 consecutive patients by the paramedics of the Madison Fire Department. For the metered-dose inhaler group, the mean value for peak expiratory flow rate for the pre-treatment test was 95.4 ±88.1 1/min, and after treatment was 109.4 ±89.3 1/min (p <0.001). For the hand-held nebulizer group, the mean value for peak expiratory flow rate before the administration of the metaproterenol was 96.1 ±76.3 1/min and following the treatment was 149.1 ±92.9 1/min (p <0.001). The mean values for the differences between the control peak expiratory flow rate and the post-treatment peak expiratory flow rate for the metered-dose inhaler group was +14.0 ±27.4 1/min, and for the hand-held nebulizer group was +53.0 ±69.1 1/min (p <0.003).Conclusions:In the prehospital setting the administration of metaproterenol using a hand-held nebulizer is more effective than delivering the drug using a metered-dose inhaler. The hand-held nebulizer is easier to use and delivers a higher dose of the drug than is convenient using the metered-dose inhaler.

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 complications have a significant impact on morbidity and mortality after major abdominal surgery. One of the major causes of pulmonary dysfunction after such surgery is restricted breathing due to pain and diaphragmatic dysfunction.Methodology :  this study investigated the effects of pre operative breathing exercises training on the vital capacity and peak expiratory flow rate of upper abdominal surgery patients. The patient were divided into 2 groups, control and experimental. Patient in experimental group were given three supervised session of diaphragmatic deep breathing exercise daily. Spirometric and peak flow meter values of vital capacity and peak expiratory flow rate were obtained one day before and 1st , 3rd , 5th, and 7th day after surgery.Result and conclusion : The data obtained were analyzed in terms of descriptive(frequency, percentage, mean and standard deviation) and inferential statistics by using soft ware SPSS – 16.1 version. The analysis showed a significant difference in the pre and post training vital capacity and peak expiratory flow rate for experimental group compared to control group. So, diaphragmatic deep breathing exercise improves the pulmonary functions after the abdominal surgery.

Background: Asthma is an abnormality in the form of chronic airway inflammation which can be reduced by providing asthma-induced gymnastics and healthy lifestyle such as consuming alkaline water.Aims: The objective of this study is to examine a combination of alkaline water provision and asthma-induced gymnastics towards peak expiratory flow rate of asthma patients at Surakarta Lung Clinic, IndonesiaMethods: This research was a quasi-experimental pre-test-post-test design with control group. The number of respondents in this study was 30 respondents, divided equally into intervention group and control group. The control group was given asthma-induced gymnastics twice a week for 14 days with duration of 60 minutes, while the intervention group was provided with a combination of alkaline water pH9+ for 14 days as much as 1,200 ml/day and asthma-induced gymnastics 4 times a week for 14 days with a duration of 60 minutes.Results: There was a significant difference in the value of peak expiratory flow for 14 days in the intervention group and the control group (p < 0.001). There was an improvement in the average of peak expiratory flow rate values for each measurement in both groups, however, this study orchestrates that the intervention group has a higher improvement than the control group. The combination of alkaline water and asthma-induced gymnastics effectively and significantly improves the peak expiratory flow rate values at the Day 8 (p = 0.039) and the Day 14  (p = 0.012).Conclusion: The combination of alkaline water and asthma-induced gymnastics can be applied in nursing care management in patients with intermittent and persistent asthma.  Keywords: Alkaline Water, Asthma Gymnastics, Peak Expiratory Flow Rate, Asthma.
