What should be monitored on oxygen tanks to ensure an adequate supply?

• A. flow rate
• B. gauges
• C. color
• D. valves

Answer: (B)

Gauges provide the readout of how much oxygen remains in the tank. Oxygen tanks are pressurized, and the gauge on the tank/regulator shows the current pressure, which you translate into remaining volume. As you use oxygen, the pressure drops, so checking the gauge tells you whether you have enough for the needed duration and when to swap or refill. The flow rate tells you how fast oxygen is being delivered to the patient, not how much gas is left in the cylinder, so it doesn’t indicate adequacy of supply over time. Color coding isn’t a reliable indicator of contents, since colors can vary and don’t reflect actual pressure. Valves control the delivery and safety, but they don’t tell you how much gas remains.
