It has been reported to the Trust of incidents where the Corpuls C3 device has failed to deliver a shock as anticipated.

To best protect the patient and mitigate any risk from a device failure all crews will please undertake the following actions which may change as new information comes to during the ongoing investigations.

All Operational resources

  • Ensure that at every shift change the device is checked on a test box with the record paper print bring retained in the shift summary envelope.
  • Where possible ensure that the second set of pads is of a different batch number to the ones installed on the device
  • The second resource to an cardiac arrest must bring to the patients side an additional C3 monitor
  • A LOM is to respond to all cases whereby a patient is being shocked or likely to be shocked as they have an alternative Zoll AED.

LOMs are to ensure that all staff on duty have sight of this instruction and that staff are briefed as part of their safety huddles at each shift change until further notice

AOC/TOC /CCD colleagues are to monitor the deployment of resources, for witnessed cardiac arrests or those that receive a shock or a shock is advised by a device undertake the following actions

  • Ensure the deployment of a resource with an alternative device such as LOM /BASICs/HEMS
  • Consider the deployment of CFR and public AEDs if there is a delay for a LOM/BASICS/HEMS in consultation with the  lead clinical coordinator on duty

These actions do not prejudge the outcome of the ongoing investigations but are additional mitigation to provide confidence for the staff and ensure the ability for crews to provide appropriate patient care.

The Trust will in the coming days work to return the Zoll AED devices that were redeployed to support the additional resources required for our Covid response.

All failures identified on testing or on scene must continue to be reported by Datix as per the existing processes, staff are reminded that any device that fails where there may have been patient harm must not be interfered with in any way to identify the reason and must be quarantined with all the accessories such as the pads that were in sure.

Even with these cases there is a very low incidence of failure, staff should retain confidence that with the measures outlines above were are still able to ensure an effective and timely response to any cardiac arrest with a low risk of adverse incidence.

Thank you for your diligence and co-operation, there will be further communication from the Trust when there is new information, until further notice the above actions remain in place.
