What happens if the nipple of the hanger yoke is damaged?

A damaged nipple of the hanger yoke primarily affects the ability to obtain a secure connection between the gas cylinder and the anesthesia machine. The hanger yoke plays a critical role in ensuring a tight seal when connecting the gas cylinder, allowing for proper gas flow during anesthesia delivery.

When the nipple is damaged, it can lead to issues such as gas leakage, which compromises the effectiveness and safety of the anesthesia delivery system. A proper seal is essential to maintain the integrity of the gas supply, and any damage can result in inadequate performance of the anesthesia machine. This is why the correct answer emphasizes the challenge in achieving a tight seal when the nipple is damaged, as it directly impacts the functionality and reliability of the system.
