It is not simply a room with bright lights and advanced technology; it is a carefully designed ecosystem where medical precision and the Specialized Indoor Environment come together.
Designing and developing a Specialized Indoor Environment for operating rooms implies much more than following sanitary regulations. It is to understand that this space must allow medical personnel to operate without distractions, safely, and in conditions that minimize the slightest margin of error. Cleanliness, ergonomics, lighting, acoustics, air flow, and even the color of the walls play a role that may seem invisible... but it is not. The materials chosen are not casual. Walls without sharp corners, surfaces that repel bacteria, conductive floors that avoid static charges, modular ceilings that integrate laminar ventilation systems to keep air moving in a controlled manner. Each element answers a single question: does it contribute to the safety of the patient and the medical team?
Inside an operating room, where concentration is sharpened like a scalpel and minutes weigh more than anywhere else in the hospital, air is not just air. It is just another surgical tool. Silent, imperceptible, but constant. Its presence - or absence - can make the difference between a successful operation and an unnecessary risk. Here, the air conditioning system is not a luxury: it is a fundamental part of the surgical ecosystem. At first glance, we might think that its function is to regulate the temperature so that the doctors can work comfortably. And while that is true, we are far from covering all its importance. Air conditioning in an operating room is designed to control three variables: TEMPERATURE, HUMIDITY AND AIR PURITY. Each of these directly influences patient safety and the performance of the surgical team.
CONTROL OF PARTICLES AND MICROORGANISMS IN SUSPENSION
Let's start with the basics: Ventilation in a specialized operating room is based on LAMINAR FLOW systems - a constant, sterile, unidirectional stream of air moving from the ceiling to the floor. This flow not only maintains a stable temperature; more importantly, it pushes any contaminating particles down and out of the operating field, reducing the risk of surgical infections. AIR FILTRATION is another key pillar. HVAC systems for operating rooms include high-efficiency HEPA Filters that trap bacteria, viruses and spores with an efficiency of more than 99.97%. Air is renewed at least 20 times per hour, creating an aseptic environment.
WHAT ABOUT THE HUMIDITY?
This detail, which is hardly considered in other environments, becomes a safety condition here. Humidity between 40% and 60% prevents the proliferation of bacteria and protects both electronic equipment and the patient's exposed tissues. Beyond that range, there is a risk of creating environments conducive to microbial growth or affecting instrument accuracy. TEMPERATURE, on the other hand, is not only intended for comfort. A room that is too cold can cause hypothermia in the patient, affecting recovery and increasing the risk of complications. A room that is too hot can exhaust the surgical team and alter the performance of medical devices. The ideal: keep it between 18°C and 22°C, depending on the type of surgery and the patient's condition.
The whole system must be almost imperceptible. Air noise should not interrupt communication. Drafts must not cause any disturbance. The system must work as another operator, unobtrusive, effective and always present. Redundant backup: emergency generators, automated sensors, remote controls. Because in an environment where life is suspended in equilibrium, nothing can fail. Yes, air conditioning in an operating room is not an accessory. It is the atmosphere that envelops every important decision, every scalpel movement, every vital sign. It is the invisible friend that allows everything else to function with the precision this place demands.
At INPAL, we understand that every detail counts when it comes to clean environments. That is why we offer comprehensive, functional and high quality solutions for operating rooms and critical areas. From panels to finishes, every component is designed to meet the highest quality standards.
If you are building or renovating a healthcare space, INPAL has everything you need to achieve a safe, efficient and state-of-the-art environment.
