The forced vital capacity, forced expiratory volume in one second, peak expiratory flow, mid-expiratory flow and maximum voluntary ventilation was measured in 632 healthy, normal children from Metropolitan city of Bombay using computerized spirometer. The children were between age range 6 years to 15 years and belong to high or middle and lower socio economic status. The pulmonary function data...

[Purpose] The aim of this study was to evaluate the changes in posture and respiratory functions depending on the duration of smartphone usage. [Subjects and Methods] Participants were randomly allocated to 2 groups: group 1 (subjects who used smartphones for <4 hours/day, n=25) and group 2 (subjects who used smartphones for >4 hours/day, n=25). The craniovertebral angles of all participants we...

BACKGROUND The objective of this study was to discuss the spirometric characteristics of anthracofibrosis which is a from of bronchial anthracosis associated with deformity. MATERIALS AND METHODS Forty anthracofibrosis subjects who were diagnosed with bronchoscopy were enrolled in this prospective study. Static and dynamic spirometry plus lung volumes and diffusion capacity were measured in t...

introduction: adenotonsillar hypertrophy is a typical cause of surgery in children. evaluation and identification of patients as potential candidates tonsillectomy is a primary concern for otolaryngologists. this study focuses on the results of pulmonary function tests (pfts) after tonsillectomy in children. materials and methods: this cross-sectional study examined 50 patients suffering from t...

Introduction: Forced expiratory value in one score  (FEV1)/ Forced vital capacity (FVC) was used in classical literature for primary classifications of pulmonary disorders. American Thoracic Society/ European Respiratory Society guidelines recommended using FEV1/VC instead of FEV1/FVC.The aim of study was determination of the extent of superiority of FEV1/VC over the FEV1/FVC. Materials and Met...

Forced expiratory volumes and flows (forced vital capacity (FVC), forced expiratory volume in one second (FEV1) peak expiratory flow (PEF), maximal expiratory flow at 25% (MEF25%), 50% (MEF50%) and 75% (MEF75%) of the FVC) have been measured in 909 healthy nonsmoking men and women, ranging in age from 18-86 yrs, who live on Eastern Adriatic islands (Yugoslavia). This area is essentially free fr...

The forced expiratory manoeuvre was first described by Tiffeneau and Pinelli working in Paris (France), in December 1947, who proposed measurement of the "pulmonary capacity usable on exercise" (capacité pulmonaire utilisable à l'effort) (CPUE), the maximal volume expelled in one second after a deep inspiration. It was intended to replace the measurement of the maximum breathing capacity, a dif...
