Abstract:
OBJECTIVE To analyze the effect of nanometer light catalysis decontamination machine on air disinfection in the hyperbaric oxygen(HBO) chamber in the hospital.METHODS The nanometer light catalysis decontamination machine was used to disinfect the HBO chamber air at the time of thirty minutes after patients leaving the chamber when the HBO therapy was finished,then the amount of bacteria in the air was monitored before and 1,2 and 3 hours after disinfection,respectively.RESULTS After disinfection using nanometer light catalysis decontamination machine,the amount of bacteria in the chamber air decreased from 764-1989 CFU/m3 before disinfection to 31-268 CFU/m3.The mean ratio of natural bacteria dissolution was more than 80%.CONCLUSIONS Using nanometer light catalysis decontamination machine is a safe and effective method for air disinfection in the HBO chamber.
