Why Air Handling system (HVAC) is necessary inside operation theater?
Heating, ventilation, and air conditioning (HVAC) is the use of various technologies to control the temperature, humidity, and purity of the air in an enclosed space. Its objective is to provide thermal comfort and acceptable indoor air quality.
What are the CDC (central depository company) Guidelines for Isolation Rooms?
- Air Filtration flow rates to attain 12 air changes per hour (ACH)
- Negative Pressure to be greater than .01 inches w.g.
- Monitoring to validate negative pressure
Air Filtration efficiency to be 99.97% or higher as measured against0.3-micronn particle size (HEPA).

Here are some specific reasons why ventilation is important in an OT:
Maintaining Sterility: During surgery, the patient's body is exposed, and the surgeon must make incisions and operate on the tissues. The air in the OT can carry bacteria and other contaminants that could infect the open wound. The ventilation system helps to control the airflow and filter out the impurities, reducing the risk of infection.
Reducing Cross-Contamination: Patients undergoing surgery are often susceptible to infections, and the medical staff in the OT must take extra precautions to avoid cross-contamination. Proper ventilation helps to control the flow of air and reduce the spread of airborne particles that can transmit infections.
Removing Odors: Surgery often involves the use of chemicals and other substances that can produce strong odors. The ventilation system helps to remove these odors from the air, making the environment more comfortable for patients and staff.
Controlling Humidity: High humidity levels in the OT can promote the growth of mold and bacteria. Proper ventilation helps to regulate the humidity levels, reducing the risk of infection and creating a more comfortable environment.
Overall, ventilation is a critical component of OT design and operation. It helps to maintain a sterile environment, reduce the risk of infection, and ensure the safety and comfort of patients and medical staff.
