What concept is exemplified when incompatible connectors on an anesthesia machine prevent improper connections?

1. Resiliency.

2. Standardization.

3. Forcing function.

4. Workaround.

The correct answer is: Forcing function.

The concept exemplified by having incompatible connectors on an anesthesia machine to prevent improper connections is known as a forcing function. A forcing function is a design feature that makes certain actions or choices impossible to ensure that users cannot make potentially harmful errors. In this case, the incompatible connectors physically prevent the connection of equipment that should not be combined, thereby promoting safety by eliminating the risk of erroneous operation that could lead to adverse patient outcomes. Forcing functions are an important part of designing safe healthcare systems and equipment because they help guide users toward correct actions without relying solely on user vigilance or training. By embedding safety features directly into the design, the system inherently protects against human error.
