Air Safety in Healthcare Settings
The National Institute of Health (NIH) released an article on March 17, 2020 titled “New coronavirus stable for hours on surfaces”. The article describes how the virus causing COVID-19 is stable for several hours on surfaces and in aerosols according to research being done at NIH, CDC, UCLA, and Princeton University published in The New England Journal of Medicine.
The scientists research found the SARS-CoV-2 virus could be detected in aerosols for up to three hours, up to four hours on copper surfaces, up to 24 hours on cardboard surfaces, and up to two to three days on plastic and stainless steel surfaces.
Out of all surfaces, aerosols are the most infectious. Aerosols can be breathed in easily when they are present in the environment, making the disinfection of aerosols in areas at high risk of spreading COVID-19 a top priority for reducing the number of COVID-19 infections; especially within a healthcare setting.
In fact, most general healthcare guidelines for reducing the spread of COVID-19 revolve around reducing contact with infectious aerosols such as:
- Avoiding close contact with sick people
- Stay at home when you are sick
- Cover your coughs and sneezes with a tissue, and immediately throw that tissue in the trash
Improving Safety through Air Quality
Air quality is one of the most simple and effective investments to make for improving safety for healthcare workers working on the front lines of the COVID-19 pandemic. Aerobiovac Canada is bringing some of the best technology in the world to Canada for removing the SARs-CoV-2 aerosols from the air with their Illuvia® HEPA-Ultraviolet Air Recirculation System.
Illuvia® is made to remove infectious diseases from the air in high traffic zones to create areas free of contaminants to reduce the possibility of patient infections. Peer reviewed scientific literature shows Illuvia® is capable of cutting air bacterial levels by over 50% in occupied operating rooms, and can produce a 41% reduction of bacterial air burden. The product does this through using a combination of a patented internal ultraviolet system, HEPA filtration, and contamination-collecting cartridge technology. Illuvia produces a disinfected, directed, and non-turbulent flow of air that has had particulate matter and microorganisms removed.
Studies of HEPA-Ultraviolet air recirculation range from laboratory testing, case studies, conference presentations, and peer-reviewed papers which have shown the technology is capable of:
- Reducing bacterial level 80 to 20 CFU/m3 in orthopaedic operating rooms
- Reducing bacterial levels 67% in general surgery operating rooms
- Reducing bacterial levels by 41% in routine care
- Reducing viable biological particle levels up to 80% in orthopaedic operating rooms
- Reducing the incidence of surgical site infections in joint procedures
- Reducing electrocautery smoke plume levels
- Reducing cardiac heater-cooler emissions
Is Reducing Infections by Improving Air Quality Worth the Investment?
The answer is obviously YES! The evidence is there, but is the motivation to reduce infections within the healthcare setting high enough to make the investment? For some places with either excellent foresight, or first hand experience dealing with infectious outbreaks, the investment in air quality improvement is already made.
Aerobiovac Canada is bringing the latest air disinfection to technology and they are reading to make Canadians, and Canadian healthcare workers, safer through their flagship Illuvia air disinfection product.
