infusion pump occlusion alarm auto reset functions

    Does anyone know of infusion pumps that automatically clears the occlusion alarms if the patients straightens his/her arm, etc.?  Then the nurse would not have to enter the room to manually clear the alarm?

    Hi Jeanette,

    I'm on-line with some pump vendors right now.  None of them have any pumps that automatically reset/clear an alarm.


    Many have the capabilities for a caregiver to remotely silence the alarm until they can get to the room and cancel it.
    They do that via the IHE Remote Alarm Management Profile, working with the alarm notification company.

    Here's a link to more info - PCD Profile Alert Communication Management Overview

    BTW - We are meeting right now, and discussing our 'Quiet Hospital' initiative.

    And a final plug to everyone - If you're interested, we'd love to have more HTM and clinician input.  Feel free to let me know.

    Hello Jeanette,

    It is not often that I find questions here that I can provide some answers to, this is one.  I work for a laboratory that conducts safety testing on medical equipment, infusion pumps are one of our specialties.  There is a safety standard for infusion pumps, IEC 60601-2-24, that contains specific requirements and tests for how the pump must respond to a downstream occlusion.  While there is some allowed variability in the requirements, the standard does require a high priority alarm (both audible and visual) in the event of a downstream occlusion.  As a general rule, a high priority alarm will stop the pump from pumping and require intervention before pumping can be resumed.

    The standard does not require specifically that the pump stop; but the definition of a high priority alarm is that immediate attention of the operator is required - this is usually interpreted to mean a high priority alarm is directly related to high/unacceptable risk to the patient and the assumption is that the safest state for the pump to go to is stopped.

    Since most infusion pumps will comply with IEC 60601-2-24 as part of their regulatory requirements (to get through the FDA); it is unlikely there are many (any) on the market that will restart if the occlusion goes away without intervention.
