Particle Counts in Hospital Operating Theatre
Particle counting is the method of sampling the airborne particle concentrations in a controlled environment (operating theatre) by means of a laser beam scattering instrument and comparing the results to an international standards system. This enables a classification of the environment (theatre) to an international standard.
Microbiological contamination of air in the operating room is generally considered to be one of the risk factors for surgical site infections in clean surgery (Landrin Bissery & Kac, 2005).
Why all the concern about dust Particle?
Dust is a bacteria carrier; it must be controlled and removed by filtration. The dirt (dust) particles measuring 5 micrometre (µm) and less can stay airborne indefinitely and travel hundreds of feet from its source by natural air currents or ventilation systems then settle down in an open wound (Mills, 2003).
4 Reasons why we connduct particle count test?
- To protect the health and safety of patients and hospital staff.
- To ensure that the ventilation system are working correctly.
- To control over clean room activities both Personnel and process.
- To comply with National Core Standard requirements to conduct particle counts in operating theatres twice annually (every 6 months) and the results are kept for auditing purposes.
