OBJECTIVES: To measure the Peak expiratory flow rate (PEFR) of healthy school children and to find out the correlation between PEFR values and anthropometric parameters, to create a nomogram of PEFR for children and formulate a regression formula for PEFR. METHODS: A cross-sectional study was conducted on healthy school children between the age group of 10 and 16 y, at three higher secondary schools selected in urban area of Jabalpur, Madhya Pradesh. After collecting baseline data, PEFR was measured using mini Wright peak flow meter...

Nebulized bronchodilator solutions are available in the United States as both nonsterile and sterile-filled products. Sulfites, benzalkonium chloride (BAC), or chlorobutanol are added to nonsterile products to prevent bacterial growth. Bronchoconstriction from inhaled BAC is cumulative, prolonged, and correlates directly with basal airway responsiveness. The multi-dose dropper bottle of albuterol sulfate solution contains 50 μg BAC per/2.5 mg of albuterol, which may be below or at the lower limit of the threshold dose for bronchoconstriction...

Exposure to iron dust and welding fumes is widespread and may increase the risk of lung inflammation. The aim of this study was to identify associations between exposure to iron/ welding fumes and the levels of inflammatory parameters and allergic mediators among 120 Egyptian males. Forty non-smoking and 40 smoking Egyptian welders as well as 40 healthy volunteers who were never exposed to welding fumes and non-smoking were enrolled in the study. Peak expiratory flow rates (PEFR) that were assessed at the shift of work in the working days revealed an impairment in lung function with the smoking workers showing the worse results, followed by the non-smoking ones as compared to the healthy volunteers...

BACKGROUND AND OBJECTIVE: To evaluate the utility of fractional exhaled nitric oxide (FeNO) in monitoring asthma control. MATERIALS AND METHODS: Steroid naïve nonsmoking asthmatics were recruited and followed for 6-8 weeks on standard treatment. Serial measurements of FeNO, peak expiratory flow rate (PEFR) variability, forced expiratory volume in 1 s (FEV1), bronchodilator reversibility (BDR), and asthma control test (ACT) score were measured at baseline and after 6-8 weeks of treatment...

BACKGROUND: Cough is an airway protective mechanism that serves to detect and forcefully eject aspirate material. Existing research has identified the ability of healthy young adults to suppress, or modify cough motor output based on external cueing. However, no study has evaluated the ability of people with Parkinson's disease (PD) and healthy older adults (HOAs) to up-regulate cough motor output. The goal of this study was to evaluate the ability of people with PD and healthy age-matched controls (HOAs) to volitionally up-regulate reflex and voluntary cough function with verbal instruction and visual biofeedback of airflow targets...

BACKGROUND: Maxillo-mandibular fixation (MMF) is a procedure still routinely practiced in developing countries. AIM: To determine the variations in pulmonary functions readings between cases treated under general anesthesia (GA) and those treated under local anesthesia (LA). METHODOLOGY: A descriptive hospital-based study of 106 patients was carried out from January 2011- December 2012. Information was obtained using a questionnaire and all study subjects had their baseline lung functions and their post-operative daily lung function parameters measured for the first week and then weekly for the next five weeks...

BACKGROUND: Asthma management guidelines recommend low-dose inhaled corticosteroids (ICS) as first-line therapy for adults and adolescents with persistent asthma. The addition of anti-leukotriene agents to ICS offers a therapeutic option in cases of suboptimal control with daily ICS. OBJECTIVES: To assess the efficacy and safety of anti-leukotriene agents added to ICS compared with the same dose, an increased dose or a tapering dose of ICS (in both arms) for adults and adolescents 12 years of age and older with persistent asthma...

BACKGROUND: The increasing importance of pulmonary function testing in diagnosing and managing lung diseases and assessing improvement has necessitated the need for locally derived reference equations from a sample of the general Nigerian population. METHODS: It was a cross sectional study in which we used linear regression models to obtain equations for reference values and lower limits of normal for spirometric indices in adult Nigerians from a sample of the general population aged 18-65 years (males) and 18-63 years (females)...

INTRODUCTION: The influence of obesity on cardio-respiratory efficiency in the various phases of menstrual cycle is not well understood until now. As majority of Indian women have a favourable attitude towards participation in sports it is significant to understand the variation in exercise performance during different phases of menstrual cycle to have an optimum performance. AIM: To evaluate the endurance capacity and cardio-respiratory responses in normal, obese and overweight female undergraduate students during different phases of menstrual cycle...

BACKGROUND: Asthma as a chronic health condition can be controlled when in addition to clinical care, adequate education and support is provided to enhance self-management. Like many other chronic health conditions improved self-management positively impacts the health-related quality of life (HRQoL). It can therefore be said that a well-structured pharmaceutical care delivery that addresses the issues related to patient education and support towards self-management stands a good chance of positively impacting asthma control...

OBJECTIVE: To assess the association of indoor environmental risk factors with respiratory function among adults in an acid rain-plagued city in China where coal use is frequent. METHODS: The subjects were randomly selected in the winter season. Information on selected home environmental factors was collected through administered questionnaires. Additionally, pulmonary function tests, including Forced Vital Capacity (FVC), Forced Expiratory Volume in 1 s (FEV1), FEV1/FVC and Peak Expiratory Flow Rate (PEFR) were also performed in participants...

BACKGROUND: Several studies investigated the effects of thoracocentesis on aspects of respiratory function without generally ensuring absence of coexistent lung pathology or homogeneity in initial size of the effusion. METHODS: We studied 90 patients aged 61.6±15.9 years (mean±SD) separated into a group A with small-sized or medium-sized effusion (A=56 patients) and a group B with large and massive one (B=34 patients). There was no significant lung lesion or cardiovascular pathology...

In this cross sectional study peak expiratory flow rate (PEFR) were estimated in pregnant women during the first trimester of pregnancy and in third trimester of pregnancy, to observe the alteration in airflow rate during pregnancy. This cross sectional study carried out in the Department of Physiology of Mymensingh Medical College, Mymensingh, Bangladesh from July 2014 to June 2015. For this purpose, total 300 women with age ranged from 18 to 35 years without any recent history of respiratory diseases were selected and divided into 100 healthy non pregnant women as control group and 200 normal pregnant women as study group...

BACKGROUND: We evaluated if incentive spirometry volume (ISV) and peak expiratory flow rate (PEFR) could predict acute respiratory failure (ARF) in patients with rib fractures. METHODS: Normotensive, co-operative patients were enrolled prospectively. ISV and PEFR were measured on admission, at 24 h and at 48 h by taking the best of three readings each time. The primary outcome, ARF, was defined as requiring invasive or noninvasive positive pressure ventilation...

The effects of tiotropium, an inhaled long-acting muscarinic antagonist, on lung function were investigated in current smokers and nonsmokers with asthma treated with inhaled corticosteroids (ICSs) and other asthma controllers: inhaled long-acting β2 agonists, leukotriene receptor antagonists, and/or theophylline. We conducted a double-blind, placebo-controlled study of an inhaled single dose of tiotropium in 9 asthmatics currently smoking and 9 asthmatics who have never smoked in a crossover manner. Lung function was measured before and 1, 3, and 24 h after inhalation of 18 μg of tiotropium or a placebo...
