What device indicates the pressure of gas remaining in a compressed gas cylinder?

The tank pressure gauge is specifically designed to measure and display the pressure of gas remaining in a compressed gas cylinder. This gauge provides essential information about how much gas is left in the cylinder, which is critical for ensuring that there is enough supply for anesthesia during procedures. Monitoring cylinder pressure helps prevent situations where a gas could run out unexpectedly during patient care, ensuring safety and continuous operation.

In other contexts, a flowmeter measures the flow rate of gases rather than pressure, while a scavenging system is used to collect and remove waste gases from the anesthesia circuit. A vaporizer is used to convert liquid anesthetic into a vapor for delivery to the patient but does not measure gas pressure.
