For the POB with Mask preflight check, which condition must be verified for the mask?

• A. Mask contained in plastic bag and connected to HI outlet
• B. Mask connected to LO outlet
• C. Mask outside bag and not connected
• D. Mask is unused

Answer: (A)

During a POB with mask preflight, the essential check is that the mask is contained in its plastic bag and connected to the HI outlet. The plastic bag keeps the mask clean and ready for immediate use, while the HI outlet provides the higher oxygen flow the mask is designed to deliver. If the mask is outside the bag or not connected, sterility and proper delivery can’t be guaranteed. A connection to the LO outlet would not provide the intended high-flow delivery, and simply being unused doesn’t verify that the system will function when needed.
