Abstract: ObjectiveTo investigate the disinfection effects of two different methods on the ventilator circuits. MethodsThe ventilator circuits which had been used by patients were disinfected by the artificial brushing method and the strict program of the full automatic cleaning-disinfecting machine,respectively.Samples from circuits were cultured after disinfection,and the numbers of bacterium colony forming unit (CFU) were counted. ResultsThe qualified rate of disinfection of the ventilator circuits by the strict program of the full automatic cleaning-disinfecting machine was 100％,which was significantly higher than that by artificial brushing method.50 samples disinfected by artificial brushing method were selected,among which 14 samples had pathogenic bacteria.100 samples disinfected by the strict program of the full automatic cleaning-disinfecting machine were selected and total bacterial count≤5 cfu/cm2. ConclusionsThe sterilization of the ventilator circuits with the full automatic cleaning-disinfecting machine is effective and safe,which can make the disinfection work more standardized.
