Perspectives on air disinfection methods in the workplace of blood transfusion services

Blood collection and preparation is a relatively open operation in a conventional environment, and is vulnerable to be contaminated by various types of airborne pathogenic microorganisms. It is important to establish stable and effective air disinfection methods for all types of environments in blood transfusion services, in order to control air hygiene quality and thus reduce the probability of contamination during blood collection. This paper analyzes and summarizes the principles, advantages, and disadvantages of commonly used chemical and physical air disinfection methods and their application status. It is suggested that over-reliance on chemical reagents and disinfection facilities be reduced, so that better results can be achieved with the combination of multiple disinfection methods and dynamic air hygiene monitoring.
