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 …

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 …

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 …

Negative pressure isolation wards are typically equipped with buffer rooms to prevent the
spread of infectious bioaerosols into clean areas and facilitate timely removal. The opening …

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 …

This paper aims to review the engineering controls for indoor air quality (IAQ) from a systems
design perspective. As a result of the review, we classify the literature content into three …

The OR demands high-air cleanliness and sterile conditions to reduce the risk of patients …

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

Understanding particle dispersion characteristics in indoor environments is crucial for
revising infection prevention guidelines through optimized engineering control. The …
