The air exchange rate (AER), defined as the number of times the air is fully replaced per
hour in an indoor space, is an important parameter affecting indoor air quality (IAQ). Hospital …

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 …

Air quality in the microenvironment of operating rooms (ORs) has attracted much attention as
surgical smoke may pose health risks. We investigated air pollution in the operating room …

A large amount of surgical smoke in electrosurgery seriously deteriorates the clean
environment of the operating room and can potentially harm medical staff and patients …

This study thoroughly investigated, using validated computational fluid dynamics (CFD)
techniques, the influences of ventilation on the fate of particles generated by patient and …

The operating room (OR) ventilation system is a primary method for reducing particle
exposure in the OR. However, most ventilation studies in operating rooms were conducted …

Abstract In Operating Rooms (OR), the transport of Colony-Forming Units (CFU) can
generate surgical site infections in patients and, as a consequence, CFU must be properly …

Maintaining air quality in operating rooms is import to prevent surgical site infections.
Surgical smoke is a risk factor for infections that can be caused by bacteria or viruses. In this …

In order to understand the physical mechanisms of the production of nanometer-sized
particulate generated from cooking oils, the ventilation of kitchen hoods was studied by …

Ultrafine particle (sub-100nm in diameter) can transport toxic chemicals into the human
respiratory system, causing more damage to macrophage phagocytosis than micron …
