Nosocomial pneumonia accounts for the vast majority of healthcare-associated infections (HAI) [1]. Although numerous medical devices have been discussed as potential vehicles for microorganisms, very little is known about the role played by oxygen humidifiers as potential sources of nosocomial pathogens [2]. In order to administer low-flow oxygen therapy, it is currently common practice in many acute care hospitals to exclusively use clean water in humidifier reservoirs. The "Guideline for the Prevention of Nosocomial Pneumonia" published by the Centers for Disease Control in 1982 serves as the main foundation for this approach [3].
