➡️ Question
A BiPAP machine that was used in the emergency department has been returned for cleaning. Which of the following agents would you recommend for surface disinfection?
A. Ethylene oxide
B. 70% ethyl alcohol
C. Alkaline glutaraldehyde
D. Acetic acid
To get this one correct, you needed to know which substance in the answer choices can be used as a disinfectant. The first answer choice, ethylene oxide, is used for sterilization in heat or moisture-sensitive items, such as plastics in respiratory care equipment. We're looking for a method of disinfection, not sterilization; so we can rule out 'A' because we know it's not the correct answer. Alkaline glutaraldehyde is used for high-level disinfection and sterilization and requires the object to be submerged in the solution for a period of time. This is not possible with a BiPAP machine; therefore, we can rule out 'C' as well. Acetic acid is a disinfectant; however, it is typically recommended for use in a patient’s home, not in the hospital, which means that we can rule out answer-choice 'D.' Remember: Alcohol-based solutions are typically used to disinfect surfaces in the hospital setting. Therefore, that is what’s recommended to clean the surface of a BiPAP machine, which should be performed before use on a new patient.
