How do you check if oxygen is flowing in the solid-state unit?

• A. Pinch middle of bag
• B. Listen for hissing
• C. Check flow meter
• D. Look for green indicator

Answer: (A)

The test hinges on using the reservoir bag in the solid-state oxygen unit to confirm gas is actually reaching the patient. If oxygen is flowing, the bag should refill promptly when you release it after pinching the middle. A quick pinch-and-release check lets you see whether there’s gas returning into the bag; if it doesn’t refill, there’s a problem with flow or an occlusion in the tubing or source. Relying on sounds or indicators isn’t as reliable here—some devices are quiet, and indicators may reflect power or status rather than actual gas flow. If the bag doesn’t refill, proceed to inspect connections, tubing, regulator, and supply to identify where flow is being lost.
