What is the sequence when a solid-state oxygen unit is needed?

• A. Secure unit strap around the leg of the passenger seat, unlock by pushing in green button and down on lever, check flow by pinching the bag in the middle, and place the mask over the nose and mouth, breathing deeply and normally
• B. Simply hand to passenger
• C. Press red button
• D. Turn unit off

Answer: (A)

The key idea is delivering oxygen quickly and reliably by a proper deployment sequence. Start by securing the solid-state oxygen unit so it stays in place—strapping it around the leg of the passenger seat keeps it stable and ready. Then activate the flow by pushing the green button and lowering the lever to unlock the unit. Before putting the mask on, check that oxygen is actually flowing by pinching the bag in the middle to see if it inflates. If the bag doesn’t inflate, there’s no flow yet and you’d need to troubleshoot before delivering to the patient. Finally, place the mask over the nose and mouth and have the patient breathe normally to receive oxygen. The other options don’t provide immediate or reliable oxygen delivery: handing the unit to the passenger delays it, and pressing a red button or turning the unit off would not establish or maintain oxygen delivery.
