Air quality in operating rooms must adhere to stringent requirements. The standard air speed should be 0.25–0.30 m/s, according to the recommendations of the Superior Health Council, report no. 8573. Traditionally, a large and significantly oversized air handling unit is installed on the roof. This unit is regulated using dampers until validation confirms that the air velocity beneath the plenum meets the required standard. This is typically checked statically once or twice a year.
Such an approach is highly energy-inefficient. The use of dampers causes substantial losses, and the air must be constantly heated or cooled, and humidified or dehumidified. Moreover, the airflow speed remains fixed, despite real-world conditions often causing it to vary significantly due to numerous influencing factors.
Operating rooms (ORs) are critical environments where air quality can directly impact patient outcomes and the efficiency of medical procedures. Traditional air handling systems in ORs often face challenges such as over-dimensioned fan groups and static pressure control, leading to inefficiencies and inconsistent air quality
In collaboration with a non-disclosed third party, sAInce.io developed the innovative Air Guard system—a comprehensive air quality control solution specifically designed for operating rooms. This advanced system addresses the limitations of traditional solutions through precise airflow management and adaptive control features.
Air Recirculation and Filtration: The Air Guard system recirculates 80% of the air through filters, ensuring a continuous supply of clean air while maintaining optimal air speed under the plenum.
Operational Efficiency: The system operates at high speed during ramp-up, low speed in idle mode, and precise speed during active operations, balancing efficiency and performance.
Three System Variants:
Basic: Constant fan speed with no adaptive steering.
Sense: Monitors and maintains constant air velocity with adaptive fan group steering.
Sense + AI: Adapts air speed based on the number of people detected in the plenum zone, optimizing for both occupancy and efficiency.
Seamless Integration: The Air Guard system communicates with building automation systems and operating room HMIs (e.g., Bender), collecting sensor data on humidity, temperature, CO2 levels, and differential pressure.
Customizable Control: The system can be configured to trigger people detection only during specific conditions (e.g., during operations) and adapt air velocity based on different operational phases (ramp-up, idle, working hours, weekends).
Advanced Features: Additional capabilities include LED lighting for alarm notifications, monitoring door contacts, and particle counter measurements.
Implementing the Air Guard system in operating rooms leads to several significant benefits:
Enhanced Patient Safety: Reduces the risk of post-operative infections by maintaining superior air quality.
Improved Comfort for Medical Personnel: Ensures a stable and comfortable working environment.
Energy Efficiency: Achieves substantial energy savings through intelligent airspeed regulation.
Superior Air Quality: Maintains a clean and controlled air environment, crucial for sensitive medical procedures.
The Air Guard system leverages sAInce.io’s cutting-edge technologies, including the smart edge controller, AI controller (for Sense + AI deployment), and Connect-and-play boxes + various sensors, to deliver a robust and intelligent air quality solution for operating rooms.
sAInce.io's collaboration with the non-disclosed third party exemplifies how innovative technology can revolutionize critical environments like operating rooms. The Air Guard system not only enhances patient health protection and operational efficiency but also sets a new standard for air quality management in healthcare settings.
