Operating airspace and breathing zone purification using a mobile air purifier in theatre

A mobile laminar airflow unit to reduce air bacterial contamination at surgical area in a conventionally ventilated operating theatre.

The aim of this study was to evaluate the efficacy of a mobile laminar airflow (LAF) unit in reducing bacterial contamination at the surgical area in an operating theatre supplied with turbulent air ventilation. Bacterial sedimentation was evaluated during 76 clean urological laparotomies; in 34 of these, a mobile LAF unit was added. During each operation, settle plates were placed at four poin...

Airspace configuration using air traffic complexity metrics

Flow regulation is a critical process in air traffic management, ensuring that the incoming traffic does not exceed the ability of air traffic controllers to handle it safely and efficiently. Currently, the european Flow Management Positions (FMP) use flight counts and sector capacities to assess the traffic load and build predicted opening schemes. These schemes, made of predefined airspace co...

Explosions in the operating theatre.

Explosions in operating theatres do not occur frequently, but unless there is constant care and watchfulness, such catastrophies can descend with tragic suddenness, and may result in loss of life or limb. Those who work in operating theatres tend to forget the dangers lurking round the corner. The writer's purpose is to bring these hazards once again to their notice, and to point out afresh som...

Asepsis in the Operating Theatre

Indoor Air Quality in a Real Operating Theatre under Effective Use Conditions

The aim of this study is to investigate the impact of surgical staff on the indoor air quality in a unidirectional ventilation Operating Theatre (OT). Experimental measurements of particles and microclimate were acquired at rest and in operational conditions. The real OT (operational) use was simulated by a sham hip arthroplasty. CFD simulations were carried out outlining the studied environmen...
