Evaluation of a pulsed-xenon ultraviolet room disinfection device for impact on hospital operations and microbial reduction

Infect Control Hosp Epidemiol. 2011 Mar;32(3):286-8. doi: 10.1086/658329.


This study evaluated the use of pulsed-xenon ultraviolet (PX-UV) room disinfection by sampling frequently touched surfaces in vancomycin-resistant enterococci (VRE) isolation rooms. The PX-UV system showed a statistically significant reduction in microbial load and eliminated VRE on sampled surfaces when using a 12-minute multiposition treatment cycle.
