Types of Rooms Shared Rooms • • • Normal air flow, ie no special air conditioning, takes about 2 hours for the air in the room to be replaced Generally not useful for infection control purposes May, if required, be used for cohorting patients with the same infectious agent (ie RSV) Single Room with Ensuite • • Normal air flow, ie no special air conditioning, takes about 2 hours for the air in the room to be replaced Can be used for isolation of patients with an infectious agent (but not by the airborne route) Positive Pressure Room • • • • • The purpose of this room is to protect the patient in the context of the patient being at significant risk of infection form microorganisms in the environment, eg allogenic bone marrow transplant recipients These rooms are NOT suitable for patients with infectious agents requiring isolation The supply and exhaust of these rooms should provide a positive pressure relative to the corridor and adjacent areas. The return and exhaust flow rates should be a minimum of 10% less than the supply air rate with all doors and openings closed. In other words: the direction of the air flow is from the outside adjacent space (ie the corridor) into the room Should have an air change rate of at least 12 air changes per hour Negative Pressure Room • • • • • • • Also called a Respiratory Isolation Room These are suitable for isolation of patients with infections transmissible by the airborne route Appropriate personal protection should be utilized by individuals entering the room The supply and exhaust of air to these rooms provide a negative pressure, relative to the corridor and adjacent areas. The exhaust flow rate should be a minimum of 10% greater than the supply air with all doors and openings closed. Therefore it is important to ensure that all doors are closed to maintain proper air flow. In other words: the direction of air flow is from inside the room to the outside adjacent space (ie the corridor) Air from these rooms should not be reticulated via or to any other ventilation system. Air should be exhausted directly to the outside of the building, alternatively air that is to be re-circulated should be directed through HEPA filters. Should have an air change rate of at least 12 air changes per hour References Standards Australia (2003); Hand Book 260, Hospital acquired infections-Engineering down the risk; Standards Australia Centers for Disease Control and Prevention (2003); Guidelines for Environmental Infection Control in Health-Care Facilities: Recommendations of CDC and the Healthcare Infection Control Practices Advisory Committee (HICPAC); Morbidity and Mortality Weekly Report; 52 (No.RR-10)
