Computerized control of the procedure for detecting and removing airborne particles in operating rooms

Area of Science:

• Infection Control
• Environmental Monitoring
• Medical Engineering

Background:

• Surgical-site infections (SSIs) remain a significant challenge in healthcare.
• While patient and healthcare worker flora cause many SSIs, the role of airborne particles is debated.
• Ultraclean air and High Efficiency Particulate Air (HEPA) filters reduce infection rates, but continuous air quality control is needed.

Purpose of the Study:

• To develop and implement a computerized system for real-time monitoring of airborne particle cleanliness in operating rooms and intensive care units.
• To establish an automated warning system for exceeding predefined airborne particle thresholds.

Main Methods:

• A computerized system was designed to measure airborne particle counts and sizes within operating rooms.
• The system was programmed to compare real-time measurements against maximum allowable values.
• Automated alerts (phone, sound, display) were configured for threshold breaches.

Main Results:

• The computerized system successfully monitored airborne particle levels in operating rooms.
• The system effectively detected when particle concentrations exceeded established limits.
• Automated alerts were triggered upon exceeding maximum particle values.

Conclusions:

• A computerized air quality monitoring system can enhance the safety of operating rooms and intensive care units.
• Real-time monitoring and automated alerts are crucial for maintaining safe air quality and potentially reducing SSIs.
• This technology provides an additional layer of control beyond HEPA filtration for airborne contaminants.
