Improving standards for hospital patient isolation rooms
Infectious diseases such as influenza, measles and COVID-19 can be spread by airborne transmission. In many cases, a patient being treated with an infectious disease is placed in a negative-pressure isolation room, which acts to contain the disease and stop it spreading to other patients or healthcare staff in the rest of the facility.
Although the current standard of continuous monitoring of negative pressure verifies that contaminated air is exhausted out and away from the patient and staff, air quality can still vary significantly between facilities. Seeking to maintain or exceed HVAC guidelines, many hospitals have adopted engineering controls that include directional airflow and technologies that are reliable, responsive, and effective in reducing airborne particulates.
Penny will compare hospital HVAC guidelines and engineering controls applied in Australia, the US and the UK with respect to patient isolation rooms. Based on these findings, the presentation will suggest a pathway for Australia to help better protect patients and healthcare staff from the risk of airborne infectious diseases.
