The use of ultraviolet light systems is becoming more common in healthcare facilities. Ultra violet lights systems are used in other industries, but they are not appreciated. Let’s figure out this mystery.
UV light is produced by the sun. The most common forms are UV-A, UV-B, and UV-C which are both long wave light and not absorbed by the ozone layer. Modern science has been able to create UV-C lighting that can penetrate the cell wall of the microorganism, and alter the DNA structure so that it is unable to reproduce or transmit a disease.

UV-B causes production of vitamins D and D2 in the skin, sunburn happens at the wavelength of the UV-B bands, overexposure to UV-B radiation can cause skin cancer, and the use of UV-C can cause skin cancer. Night time cleaning of laboratories and meat packing facilities is done with the help of UV-C. Ultraviolet Germicidal Irradiation is a term used for UV-C.
The 4th leading cause of death in healthcare facilities in Canada is healthcare acquired infections. The built environment can contribute to the reduction of HAI’s by using traditional prevention and control strategies.
portable UV-C systems are one of the most popular ways to destroy organisms. A Canadian company called Sanuvox makes a twin unit that can be placed in the patient room with one unit on either side of the bed, and the corridor door closed, to cover off the shadow effect, and to prevent a patient from being seen. The UV-C lights can be turned off if there is no movement in the room, and can be activated remotely via smart phones and wireless applications. The distance from the light to the bed, wall, and the intensity of the bulbs are measured.
The distance is 5 feet. 6 feet. 7 feet. 8 feet. 9 feet. Pneumonia Seconds 18 24 30 42 48 60 VRE Seconds 30 36 42 54 66 78 MRSA Minutes 1.2 1.6 2.1 3.2 3.8 C diff Minutes
The patient room can be cleaned in less than 15 minutes. Thebathroom phone sanitizeris smaller than the other one so it would take less than five minutes to clean one of these units. The environmental services staff still have to clean the patient room in their usual manner and we still have to wash our hands.

The air of bothbacteria andviruses can be destroyed by placing another Sanuvox UV-C product in the heating and air conditioning system. The main unit can be placed in the ducts or inside. Stand-alone units can be placed in the bathroom of patients above the door to clean on a cycle basis. The patient with C diff. has their feces deposited onto the bathroom surfaces. The bathroom UV-C light will turn on when the door is closed and the patient is not in the room, and it will be free ofbacteria and viruses in 5 minutes. There are cases in the operating room.
York Air Conditioning is making a unit with UV-C lights. A typical configuration for high risk health-care application places the UV-C lights downstream from the cooling coil to deal with the micro-organisms and upstream of a high efficiency HEPA filter to eliminate airborne bacterial and viral contaminates. The York Solution UV-C system was developed with their partners.
The table shows the effectiveness of the York Solution UV-C system.
Air changes per hour are good for four single passes and six good passes.
Here are a few examples of real life. The clinical pregnancy rates were increased from 38.9 to 62.3 per cent after the In-vitro Fertilization Laboratory installed UV-C cleaning in their heating and cooling system. The Women’s & Children’s Hospital of Buffalo, NY reported that e UVGI eradicated microbes in the air conditioning system. The study found that there were significant reductions in VAP and antibiotic use in high-risk patients.
TRU-D Smart UVC has deployed two machines at JFK Hospital in JFK, New York and the ELWA Hospital in the Republic of Liberia. They are helping to clean healthcare environments. TRU-D is a new technology that is critical to creating and maintaining a pathogen-free environment for patients and healthcare staff.
UV-C is a real cleaning method. Use these systems to reduce HAI’s.
