Hospitals around the world are using ozone generators to clean
Decontaminate or sterilize operation room between surgeries.
Operation rooms are cleaned and then sealed airtight before
being filled with ozone which effectively kills or neutralizes bacteria.
It is very important to maintain good indoor
air quality (IAQ) in Operation Rooms to ensure health and safety
for the patient and surgical team. A significant consideration
in Operation Theatres is the control of aerosols, anesthesia
gases and smoke. Aerosols are solid and liquid particles.
• A significant consideration in Operation
Theatres is the control of aerosols, anesthesia gases and smoke.
In Operation Theatres, however the main sources have an indoor
origin are the patient, the surgical team and equipment. The
anesthesia gases dispersed in Operation Theatres 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.
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 Operation Room 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
Operation Theatre 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 Operation Room 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
• Controlled Ozone is injected in the
mainstream air in the return air duct. It is present in the
indoor space at the times at low concentration. When it
encounters chemical pollutants, it almost instantly oxidize them
and keeps the indoor air free of chemical pollutants VOC as
interferes with metabolism of cell multiplication of fungi
resulting in the reduction of fungi along which is responsible
for vide range of indoor related allergies.
• Use of Ozone Generator in Operation
Theatre Fumigation will reduce the electricity consumption &
also no long hour sterilisation before and after operation.
