Air filtration and prevention of aspergillary pneumopathies. Preliminary comparative study of two mobile units for bacteriological air purification with recycling.
Two mobile units for air filtration with recycling designed to reduce the aerobiocontamination of hospital rooms were tested. Their efficacity was evaluated by measurement of particle retention and by quantitative determination of the reduction of aerobiocontamination in rooms occupied by patients. Results show a significant improvement in the aerobiocontamination of test rooms as compared to control rooms. It is thus reasonable to suppose that these systems may provide a practical solution to the problems posed by hospitalization in ordinary rooms of patients subjected to aplasive chemotherapy. A randomized clinical trial is in progress.
