What regulates the flow of medical gas from a cylinder to ensure safety?

The regulator is a critical component in the safe delivery of medical gas from a cylinder. Its primary function is to reduce the high pressure of gas stored in the cylinder to a lower, manageable pressure suitable for medical use. This ensures that the gas flows at a consistent, safe rate while minimizing the risk of burst or other hazards associated with high-pressure systems.

The regulator is equipped with a mechanism that controls the flow of gas based on the needs of the medical device or system to which it is connected. It provides precise control over the delivery pressure, ensuring that the medical gas is administered at optimal levels for patient safety and equipment efficacy.

In contrast, while devices like the flowmeter and pressure gauge also contribute to monitoring and controlling gas flow, they do not directly reduce the gas pressure from the cylinder. The inlet valve serves as a point of connection but does not inherently regulate flow. Therefore, the regulator's unique role makes it indispensable in medical gas safety practices.
