Fumigation is the process by which we can sterilize the enclosed area by injecting the chemical which will kill or destroy microbes present in the air. This process may be used in order to rid a home or other structure of insects such as termites or cockroaches, but it may also be used when products are being processed for export or import in order to rid the goods of exotic pests and organisms.
• It is very important to maintain good indoor air quality (IAQ) in OR to ensure health and safety for the patient and surgical team. A significant consideration in ORs is the control of aerosols, anesthesia gases and smoke. Aerosols are solid and liquid particles,
• It is very important to maintain good indoor air quality (IAQ) in OR to ensure health and safety for the patient and surgical team.
• A significant consideration in ORs is the control of aerosols, anesthesia gases and smoke. In OR, however the main sources have an indoor origin are the patient, the surgical team and equipment. The anesthesia gases dispersed in ORs are also considered as pollutants. The anesthesia gases are dispersed in the environment through problems in the equipment and from the exhalations of the patient. Some gases used in the surgery, for example, NO2 will continue to be exhaled by the patient for up to one hour after the surgery is finished. During surgery the highest concentration of gases is on the floor. However, with the movements of people these gases can be mixed with room air and inhaled by the surgical team.
• The concentration of gases in the OR is critical and needs to be controlled; otherwise the productivity and quality of the work of the surgical team can decrease, and in the medium and long term health problems may occur.
• Halothane gas, for example, has a high toxicity and can affect the central nervous system. The gas concentration is controlled by the air change rate in the OR by dilution to acceptable levels.
• The smoke can be generated by laser or electro surgery unit. “Research studies have confirmed that this smoke plume can contain toxic gases and vapours such as benzene, hydrogen cyanide, and Formaldehyde, bioaerosols, dead and live cellular material (including blood fragments), and viruses. At high concentrations the smoke causes ocular and upper respiratory tract irritation in health care personnel, and creates visual problems for the surgeon.
• In some critical situations the indoor air in OR will be ultra-cleaned, for example, for orthopedic surgery, traumas, implants, burn patients, and other situations where the patient is
immune compromised. Otherwise, when the surgery is septic, there should be also a higher control in the indoor environment, to protect the adjacent areas.
• In OR Air Conditioner duct system instilled.
• Duct mounted Ozone generators the released ozone combines with the mainstream air in the
