Drug delivery from a Dry Powder Inhaler (DPI) is dependent on the peak inspiratory flow rate (PIFR) generated. Currently available methods for estimating PIFR from most DPIs are limited and mainly rely on subjective assessment. We aim to show that spirometric and Diskus™ PIFR and Inspiratory Vital Capacity (IVC) are related to the underlying respiratory condition and that spirometric PIFR can b...
Abstract Background: Tile workers are exposed to a lot of dusts and are susceptible to various pulmonary complications. This study was designed to evaluate the respiratory symptoms and lung capacities of tile workers. Methods: This was a retrospective, cross sectional study on 350 workers in different factory workshops. We assessed respiratory complaints and pulmonary function tests. Data wer...
It is a well-known fact that thoracoplasty places a severe strain on the patient, affecting in particular the interchange of gases. Stead and Soucheray (1952), of Minneapolis, studied these problems during the first 16 to 20 hours after thoracoplasty operations. It must suffice here to mention some of the principal data in their investigation. They found a substantial increase in the respirator...
BACKGROUND There have been few published studies on spirometric reference values for healthy children in China. We hypothesize that there would have been changes in lung function that would not have been precisely predicted by the existing spirometric reference equations. The objective of the study was to develop more accurate predictive equations for spirometric reference values for children a...
Introduction: Silica dust is one of the most dangerous substances in the workplaces inducing a respiratory disease. Inhalation of silica particles at high levels can cause silicosis, a special form of interstitial lung disease. One way to monitor and control the effects of silica dust on workers is the study of changes in spirometric parameters. This study aimed to investigate the changes in sp...
OBJECTIVES Korean regression models for spirometric reference values are different from those of other ethnic groups. The purpose of this study was to evaluate discordance in spirometric interpretations based on using Korean reference equations versus non-Korean reference equations. METHODS Spirometry was performed on 825 Korean male workers from April 2009 to November 2011. The spirometric p...
BACKGROUND To correctly interpret spirometric results, reference values should come from the same population. Current spirometric reference equations have been under scrutiny due to deficiencies to fit adequately for Chilean population, specially, for those aged over 65 years old. AIM To develop new spirometric reference values for Chilean adults, based on national studies in which spirometri...
