The authors conclude: “Although the use of UVC light represents a departure from the standard HVAC design used in many IVF laboratories, the current study suggests that the use of UVC germicidal technology in the HVAC system serving the IVF laboratory may play a critical role in providing optimal ambient air towards improved clinical outcomes. The current study demonstrated that a clinically significant relationship existed between the replacement of the Ultra Violet C Emitters and the associated clinical pregnancy rates.”
Robert Scheir, Ph.D., president of Steril-Aire, Inc., states:“This new data provides scientific evidence of the germicidal benefits of UVC technology. The potential benefits are far-reaching: not only for the potential to improve CPR in IVF clinics, but also for enhancing infection control in hospitals and healthcare environments, and for maintaining better ambient air in medical and pharmaceutical manufacturing clean rooms.”
Scheir adds: “The study also confirms the importance of adequate UVC output and changeout frequency in achieving desired results. The study used high-output Steril-Aire UVC lamps with a changeout schedule of 6-9 months. In the 3 of 13 UVC replacement test quarters that did not result in improved clinical pregnancy rates, outside factors may have played a role in the outcomes. As long as the lamps were functioning properly and were changed on schedule, results were consistently positive. The message to anyone using UVC is that it is critical to select a device with adequate output and to replace the device consistently at required intervals to maintain that output. Otherwise, germicidal effectiveness will be diminished.”
