Using vaporized hydrogen peroxide for anhydrous disinfection of gastrointestinal endoscopes

Figure 4 Log reductions of spores on bacterial carriers in the testing devices treated with various relative humidities (60%-90%), exposure dosage (24-45 mg/L/hour), relative humidities (0. 8-2.2 L/minute), and organic burdens. A and B: Log reductions of spores by vaporized hydrogen peroxide (VHP) under various relative humidities (RHs) (60%-90%); C and D: Log reductions of spores by VHP under various exposure dosage (24-45 mg/L/hour); E and F: Log reductions of spores by VHP under various FRs (0.8-2.2 L/minute); G and H: Log reductions of spores by VHP under various organic burdens. ^aP < 0.05; ^bP < 0.01; ^cP < 0.001; NS: Not significant; BC: Bacterial carrier; BSA: Bovine serum albumin.
