Abstract:
Objective To compare the effect of multifunction air disinfection machines with ultraviolet light disinfection and natural ventilation in the improvement of air quality in respiratory wards, so as to provide reference evidence for the effective control of hospital infection rates. Methods Four respiratory wards were divided into four groups, and the total number of air bacteria in these wards after three kinds of effective disinfection were compared.Results There was no significant difference about the total bacterial count among four groups before disinfection. 30 min after disinfection, there was still no significant difference, but the total bacterial count with different disinfection methods were statistically different after 60 min and 120 min.Conclusions Three kinds of disinfection all can effectively improve the air quality in wards. But the sterilization effect of air disinfection machines and ultraviolet light are better than natural ventilation, and the using environment of air disinfection is better than ultraviolet light disinfection.
