Manufacturer Narrative

Follow up is on going to clarify whether the devices are available for evaluation.An investigation has been initiated to consider any potential factors that may have contributed to this complaint.A supplemental report will be forthcoming with the evaluation results.The exact lot number was unknown, therefore review of the manufacturing records could not be completed.Patient demographics were requested but unable to be obtained.

Event Description

It was reported that previous events occurred with disposable pressure transducers (dpts) in which the measured invasive blood pressure was considerably higher than the blood pressure the cardiologists measure.The cardiologist used philips hemo system with an acist cvi angio touch kit and a technician was present to calibrate the devices but no problems were found.As stated by the nurse, an error could not be identified but the measurement variants that are too large to be indifferent.Blood pressure was treated based on these measures and sometimes very aggressively.There was no error message displayed in none of the cases.The exact amount of patients and devices involved is unknown.Several attempts for events investigation were made however no further information was provided.

Manufacturer Narrative

Additional information was received that the patients were not treated based on the erroneous values.The statement included in the initial mdr was referring to the usual protocol for treatment for low blood pressure.

Manufacturer Narrative

It was confirmed that the device was not available for evaluation as it was discarded by the facility.Without return of the unit it is not possible to determine if some damage or defect existed on the unit that could have contributed to the event.It is not known if some procedural factors may have contributed to the event.Per the ifu: poor dynamic response can be caused by air bubbles, clotting, and excessive lengths of tubing, excessively compliant pressure tubing, small bore tubing, loose connections, or leaks.The assembly may be tested for dynamic response by observing the pressure waveform on an oscilloscope or monitor.Bedside determination of the dynamic response of the catheter, monitor, kit and transducer system is done after the system is flushed, attached to the patient, zeroed and calibrated.A square wave test may be performed by pulling the snap tab device and releasing quickly.Pressure readings can change quickly and dramatically because of loss of proper calibration, loose connection, or air in the system.Abnormal pressure readings should correlate with the patients clinical manifestations.Complaint histories for all reported events are reviewed against trending control limits on a monthly basis and any excursions above the control limits are assessed and documented as a part of the monthly review.H3 other text : device discarded by facility.
