Pump controls should resist tampering by the patient or visitors, even if the pump's front-panel lockout feature is not engaged (e.g., at least two steps should be required to change
the settings). Preferably, the pump's user interface should allow for password-protected lockouts.
A PCA pump should require both the medication chamber and its controls to be secured in order for infusion to occur. The pump should also lock to an IV pole.
Changing pump settings during infusion should require confirmation. If the user changes the flow setting but does not confirm/activate the change, an audible alert and message
should indicate that the pump is still infusing at the previous flow setting.
The administration set should be designed to prevent incorrect positioning within and accidental removal from the pump.
Administration set connections between the pump and the patient should resist accidental separation (e.g., through the use of Luer-lock connectors). Separation of components
could result in air embolism or blood loss.
