background and purpose: many workers are exposed to workplace hazards. many occupational diseases are preventable by personal protective devices (ppds). though many workers do not use ppds or their protection by ppds is not sufficient. this study was designed to assess the quality of ppds usage among industrial workers. materials and methods: in a cross-sectional study, 648 workers from four ma...
Background: The occupational exposure conditions such as dust concentration, exposure time, smoking status and use of respiratory protection device are effective on pulmonary function disorder. The aim of this study was to determine the risk of pulmonary function disorder in the workers exposed to silica dust in the stone crushing by using Cox regression model. Method: 117 of workers employ...
background the forced oscillation technique (fot) is a non-invasive means of measuring respiratory resistance and reactance. we tested our hypothesis that endotracheal intubation would cause more substantial preoperative increases in fot parameters than a supraglottic airway device (sgd). methods forty patients requiring general anesthesia and mechanical ventilation for transurethral bladder tu...
INTRODUCTION Mortality of severe acute respiratory distress syndrome in adults is still unacceptably high. Extracorporeal membrane oxygenation (ECMO) could represent an important treatment option, if complications were reduced by new technical developments. METHODS Efficiency, side effects and outcome of treatment with a new miniaturized device for veno-venous extracorporeal gas transfer were...
Idiopathic interstitial pneumonia frequently causes severe pulmonary restriction that in turn makes mechanical ventilation difficult. We report the case of a 44-year-old woman who developed a refractory severe hypercapnic respiratory failure (P(aCO(2)) 281 mm Hg, pH 6.77) despite mechanical ventilation with high inspiratory pressure and PEEP. A pumpless extracorporeal lung assist device, Noval...
The Extracorporeal CO2 removal device (ECCO2RD) is used in clinics to treat patients suffering from respiratory failures like acute respiratory distress syndrome (ARDS) or chronic obstructive pulmonary disease (COPD). The aim of this device is to decarboxylate blood externally with low blood flow. A mathematical model is proposed to describe protective ventilation, ARDS and an extracorporeal CO...
Respiratory acidosis can become a serious problem during protective ventilation of severe lung failure. A pumpless arteriovenous interventional lung assist (iLA) for extracorporeal carbon dioxide removal has been used increasingly to control critical respiratory situations. The present study sought to evaluate the factors determining the efficacy of iLA and calculate its contribution to gas exc...
BACKGROUND To evaluate barrier protective properties of Rhinosectan® spray, a medical device containing xyloglucan, on nasal epithelial cells (MucilAir). METHODS MucilAir-Nasal, a three-dimensional organotypic (with different cell types) airway tissue model, was treated with the medical device Rhinosectan® (30 µL) or with controls (Rhinocort-budesonide-or saline solution). The protective barr...
