Positive Pressure Isolation

Positive Pressure Isolation

Positive pressure isolation is used to protect patients with weakened immune systems from airborne contaminants in the hospital environment. These immunocompromised patients include cancer, burn, leukemia and AIDS patients and those who have recently gone through bone marrow or organ transplantation.

Building positive pressure isolation rooms with Genano is easy and highly cost-efficient. Only minor piping work is needed to connect the Genano air purifier to central ventilation. All of the supply air enters the room through the unit. Genano Technology effectively collects airborne microbes and eliminates them inside the unit.  The unit can simultaneously be used to create positive air pressure inside the room. This prevents non-hygienic air from other premises from entering the room.

In addition to supply air, staff, visitors and equipment can carry pathogens and other contaminants into the room. Therefore a second unit is utilized to constantly circulate and purify the air from any process and human-related contaminants.

Technical Aspects

  • The room must maintain a positive pressure (5–10 Pa) relative to adjacent spaces (corridor, toilet). Supply air should be at least 20 % more than the exhaust air. The actual air flow differential will need to be determined according to the situation.
  • The supply air should be delivered into the room through a Genano air decontamination unit.
  • This setup does not require an anteroom, unless simultaneous airborne infection isolation (negative pressure) is needed.
  • For optimal results, the room should be equipped with an extra Genano unit to recycle the air and decontaminate all pathogens created inside the room.
  • Air change rate should be 6–10 ACH.
