In the absence of piped gas, what type of yoke system is advisable for use, especially for oxygen?

• A. Single yoke
• B. Triple yoke
• C. Double yoke
• D. Multi-gas yoke

Answer: (C)

In scenarios where piped gas is unavailable, utilizing a double yoke system is advisable, particularly for oxygen. A double yoke system provides secure and stable attachment for two oxygen tanks. This setup not only ensures that the anesthesia machine has a continuous and reliable source of oxygen by allowing for a backup tank, it also facilitates the switch between tanks without interrupting the gas flow.

In this arrangement, while one tank is in use, a second tank can be prepped and positioned within the yoke, ensuring readiness for immediate use when the first tank becomes depleted. This significantly enhances patient safety during procedures by preventing oxygen shortages. Moreover, the design of a double yoke allows for proper alignment and connection of the gas supply, ensuring minimal leakage and optimal performance of the anesthesia machine.

In contrast, single yoke systems would limit reliance to only one tank, increasing the risk of oxygen depletion during critical moments. Options like triple or multi-gas yokes are more complex configurations intended for specific multi-gas applications and do not focus specifically on maximizing oxygen supply continuity, making the double yoke the most practical and effective choice in the absence of piped gas sources.
