In some cases, emergency surgeries might be required for patients whose COVID status is unknown. In some cases, patients with a negative COVID test result on the day of surgery could turn out to be COVID positive a few days after the surgery. If the patient had turned out to be COVID positive on the day of the surgery, they could expose the surgical team to the risk of contracting the disease. Further more, it also could severely strain the financial and human resources in the hospital due to the mandatory screening and quarantine required for the exposed healthcare staff members. To mitigate this risk, many hospitals are converting their operating rooms from one working in a positive pressure to a negative pressure or into a non-re- circulatory air conditioning system. While this might prevent the spread of infectious agents expelled by the patient to the other parts of the hospital, it does not address the possibility of spread into the operating room environment, thereby putting the surgical team to a risk. In some cases, it could compromise the air quality inside the operating room leading to infections for the patient. Under these circumstances, PNUETRON ACES becomes the perfect companion to handle these risks and to protect the health care staff and the other patients in the hospital. PNEUTRON ACES can be used to effectively and quickly upgrade a standard operating room to a one that can be safely used for operating on patients with suspected or confirmed Airborne infectious diseases. PNEUTRON ACES would be very helpful to protect the surgical team, the operating room environment and the other people in the hospital from infection spread. The PNEUTRON ACES consists of a "Containment Suction Hood" (CSH) and a "Extract Air Treater" (EAT), interconnected with flexible ducts. The CSH is a passive enclosure, made of transparent poly carbonate material that acts as a containment hood. The CSH is positioned on the operating table covering the patient's head and neck. The EAT is a dynamic unit that extracts the air from the CSH, irradiates it through a UVGI zone (optional) and filters it through a HEPA filter before discharging it back into the operating room.
