Ventilation System Performance on Pathogens Transmission in Healthcare Isolation Rooms: A Review

Mohd Hazzah Ahmad Siron,Mohamad Asmidzam Ahamat, Md Amin Md Nor,N Mahyuddin,

The focus of the healthcare sectors is not only to assist patients’ recovery but also to minimize the potential nosocomial infection. An effective and efficient ventilation system will thus ensure that the cross infection will be minimized and shortened the patients stay in the healthcare wards. The objective of this paper is to provide a review on ventilation system in an airborne infection isolation room based on simulated and experimental studies towards minimizing the potential airborne cross infection in healthcare facilities. Thorough review from the literatures between the year 2006 and 2016 on the simulation and experimental studies on ventilation performance specifically on negative and positive pressure isolation rooms were studied. The findings show that the current standards on isolation rooms are still not within the requirements especially in preventing cross contamination. As the results, new types of ventilation system which are different than the current ventilation system need to be developed that will prevent cross infection.
