How can cross-contamination be prevented in medical gas systems?

Preventing cross-contamination in medical gas systems is vital for ensuring patient safety and the effectiveness of the gases being delivered. Utilizing proper backflow prevention is the correct approach because it involves implementing devices that stop the reverse flow of gases. This is crucial in preventing contaminated or non-medical gases from mixing with the medical gases that are designed for patient use.

Backflow prevention devices effectively block any inadvertent backflow that may occur due to pressure changes or other disturbances in the gas delivery system. They help maintain the integrity of the medical gas supply, ensuring that patients receive only the pure gases intended for their treatment.

The other choices suggest methods that do not contribute to effective prevention of cross-contamination. For instance, low-quality components could actually increase the risk of leaks and contamination, while just running more gas lines or increasing pressure may create additional risks without addressing the core issue of preventing unwanted flow from contaminated sources into the medical gas system.
