[New operating rooms: problems related with ventilation and air quality].

: Realizing the project of the new operating theatres, We bring out the importance of creating bright environments, rational and wide ways, a good indoor air quality, thermal comfort and occupational hygiene. Therefore for the first time We've installed an automatic system for permanent monitoring of gases, vapours and particles, associated with the study of ventilation, to evaluate the real condition of the mantenance and of staff behaviour.
