Ventilation systems are the primary way of eliminating airborne pathogenic particles in an
operating room (OR). However, such systems can be complex due to factors such as …

The nature and airborne dispersion of the underestimated biological agents, monitoring,
analysis and transmission among the human occupants into building environment is a major …

The present study examines the effect of medical staff's turning movements on particle
concentration in the surgical zone and settlement on the patient under single large diffuser …

Experimental and numerical investigations were performed in a research operating room to
compare laminar air flow and turbulent mixing ventilation systems in reducing the …

In this study, a systematic procedure for establishing the relationship between particulate
matter (PM) and microbial counts in four operating rooms (ORs) was developed. The ORs …

The infectious pathogen-laden aerosols generated by infected patients have a significant
impact on the safety of surgical staff in highly clean negative-pressure operating rooms …

An air curtain is an aerodynamic barrier for regional isolation and protection; however,
research on its application in ventilated rooms is insufficient. This study investigated the …

Operating rooms (ORs) often have door openings connected to uncontrolled areas that are
more contaminated. Opening the door may allow an inflow of contaminated air, degrade the …

Background The origin of surgical site and biomaterial-associated infection is still elusive.
Micro-organisms contaminating the wound may come from the air in the operating theatre …

Abstract The Heating, Ventilation and Air Conditioning (HVAC) system in an Operating
Room (OR) has two main functions: evacuate contaminants to guarantee an elevated Indoor …
