Neurally adjusted ventilatory assist (NAVA) relies on the patient’s electrical activity of the diaphragm (EAdi) for actuating the ventilator. Thus a reliable positioning of the oesophageal EAdi catheter is mandatory. We aimed to evaluate the effects of body position (BP), positive end-expiratory pressure (PEEP) and intra-abdominal pressure (IAP) on catheter(More)
Chromium concentrations in the air were measured in seven different workroom environments, where exposure to water soluble hexavalent or trivalent compounds was expected. Urinary excretion of chromium was measured before and after the same arbitrarily chosen working day. End-of-shift urinary chromium and its increase above pre-exposure levels were closely(More)
INTRODUCTION A reliable prediction of successful weaning from respiratory support may be crucial for the overall outcome of the critically ill patient. The electrical activity of the diaphragm (EAdi) allows one to monitor the patients' respiratory drive and their ability to meet the increased respiratory demand. In this pilot study, we compared the EAdi(More)
This communication deals with an aspect of occupational hygiene in a factory producing granite cutting diamond wheels by sintering, in moulds, of fine cobalt powder. The factory has been studied between 1988 and 1991; the Department of Preventive and Occupational Medicine of the Local Sanitary Unit of Reggio Emilia has followed the evolution of the local(More)
The lung uptake and excretion of cyclohexane were studied in five workers and three volunteers in a shoe factory. Air samples were collected from the breathing zones with personal samplers, and simultaneous samples of inhaled and alveolar air were collected with the aid of a Rhan-Otis valve. Cyclohexane was absorbed on activated NIOSH approved charcoal(More)
Fifty-six males workers exposed to rock wool during production, and 20 referents were examined. Exposure, evaluated by personal sampling, ranged from 0.05 to 0.74 fibres/ml (median 0.15). The subjects underwent a medical examination, chest X-ray according to ILO recommendations and pulmonary function tests. In all subjects the serum levels of type III(More)
Lung function tests were examined on 28 welders using high chromium alloyed electrode for two years. Respiratory function change seem to be related to the duration of employment as welders. On the contrary, obstructive disease and alveolo-capillary impairment were found with same prevalence in groups of workers differently exposed to chromium. It presumably(More)
Biological and environmental monitoring of chromium exposure was carried out on 20 welders working with special electrodes in the manufacture of tank-cars. The workers were divided in groups, according to the different degree of chromium accumulation, which was determined by renal clearance of diffusible chromium. A closed linear relationship between TWA(More)
