| Summary: |
Even the best technical
and organizational methods will not prevent the
infection of the spot being operated on. The risks may
be caused for example by the microbial air pollution of
the operating theatre. Ways of air decontamination for
the purposes of air conditioning and ventilating used in
the operating theatre are both up-to-date and essential.
Decontamination methods involve filtration by means of
HEPA, ULPA, EU-13 filters with 99.99% effectiveness for
≤ 0.1 μm particles. The most suitable sterile air flow
is a displacing, vertical, ceiling system e.g. 3.2 x 3.2
m according with the requirements of the laminar air
flow (LAF) at the speed of 0.3-0.5 m/sec. The above
system should provide 1 cfu/m3 over the operating
theatre and „safe bio conditions” at 30-100 cfu/m3
during at least 3-hour work.
Decontamination by means of filtration is cost effective
both in production and in use: the cost of filters
exchanging, humidification, the problem of Legionella
pneumofila or the air cooling system. MFI (Multifunction
Ion Air Cleaning) does not show the abovementioned
limitations. The method makes use of the combination of
the ionising processes and electrostatic attraction of
particles > 0.003 um which include cells of bacteria,
fungi and some viruses. MFI technology used in Nanobio E
310 (Genano) working at 250 m3/h allows for eliminating
microorganisms from the air at ≤ 1cfu/m3. These
decontamination methods make it possible to achieve
appropriate microbiological standards when the appliance
is properly used. |
