St. Luke’s Hospital at The Vintage Reduces Risk associated with Airborne Hospital Acquired Infections

To take additional steps in reducing risks associated with airborne hospital acquired infections, St. Luke’s Hospital at the Vintage (SLHV) is the first hospital in Greater Houston to take good air, mandated by current code, and turn it into the best air available by using advanced oxidation technology.
Nosocomial, or hospital-acquired, infections in the United States are from 20,000 to 80,000 deaths and cost an estimated $4 billion annually. Sources indicate that approximately 10 to 15 percent of nosocomial infections are from airborne pathogen transmission.1,2 Many people believe that by installing regular HVAC systems per regulatory requirements will result in sterile air , but this is not always the case. Various infectious particles can be less than 4nm in size, and are able to be re-circulated in an indoor space without being caught in the filters.3

SLHV has installed the Trane Catalytic Air Cleaning System, developed by Genesis Air. This air cleaning system uses photocatalytic oxidation to not only kill bacteria cells, mold spores, and viruses, but to also decompose the cells. The hospital is able to target the prevention of airborne infections in areas where the risk of infection is greatest by installing this advanced oxidation technology in the Emergency Department, Operating Rooms and C-section suites.

Another benefit of the Trane Catalytic Air Cleaning System is odor reduction. The system breaks down volatile organic compounds, such as formaldehyde, waste odor, tobacco odor, engine exhaust (heliports, emergency generators, ambulances, etc.) and other hydrocarbon molecules, by destroying molecular bonds.
