Users with long fingernails may damage the print on the pump keys, making them unreadable. For example, cleaning the pump, as the user-maintainer believes is acceptable practice, may damage the pump, making it unreliable for clinical use. Pump labels or components become damaged under routine use.For example, the user may enter weight in pounds when the infusion pump requires it in kilograms. The infusion pump screen doesn’t make clear which units of measurement the user is expected to enter.The design of the infusion pump screen confuses the user, or the infusion pump does not respond as it should (i.e., with a warning or alarm) when inappropriate data is entered.Inadequate user interface design (" human factors" issues ): The infusion pump generates an occlusion alarm in the absence of an occlusion.The infusion pump fails to generate an audible alarm for a critical problem, such as an occlusion (e.g., clamped tubing) or the presence of air in the infusion tubing.For example, the user programs an infusion rate of 10 mL/hour, but the device registers an infusion rate of 100 mL/hour. The infusion pump interprets a single keystroke as multiple keystrokes (a problem called a “key bounce”).This occurs in the absence of an identifiable problem. A software error message is displayed, stating that the pump is inoperable.Inadequate user interface design (“human factors” issues).
