Event Description

It was reported that during colorectal surgery, while monitoring a patient with the clearsight system; pump unit, pressure controller, heart reference sensor and ev1000ni system, there was a discrepancy in the systolic blood pressure reading.The reading measured 20-30 points different from the blood pressure cuff.There was also a discrepancy in the map values.The clearsight system components were removed from the patient when the discrepancy in values was observed.No troubleshooting was done to isolate a suspect component.The patient demographics are unknown.There was no treatment administered to the patient in conjunction with the inaccurate values.There was no harm or injury to the patient.

Manufacturer Narrative

One ev1000ni pump unit was received for product evaluation.The pump unit was connected to a known good working clearsight system for testing.The pump unit did not produce any issues when tested.It was able to perform zeroing three times without any error messages.A normal waveform and normal blood pressure readings were able to be displayed three times without any issues noted.The calibration test was performed and it passed the test.There was no defect found.The device service history record review was completed and all manufacturing inspections passed with no non-conformances.The reported event was not confirmed by evaluation.There are no indications or evidence that a manufacturing defect is responsible for the reported issue.It could not be determined if any procedural factors may have contributed to the event.With any hemodynamic monitoring, pressure readings can change quickly and dramatically.Pressure readings should correlate with the patient¿s clinical manifestations.Issues such as poor finger perfusion, improperly applied finger cuff, incorrectly sized finger cuff, improper application of the hrs or failing to zero the hrs sensor may lead to inaccurate hemodynamic measurements.The operators manual instructs the use on these above stated factors that can lead to inaccurate values.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 part of this monthly review.No further actions will be taken at this time.Please refer to 2015691-2016-03603 for the ev1000ni pressure controller unit; 2015691-2016-03604 for the ev1000ni heart reference sensor; 2015691-2016-03605 for the ev1000a platform system associated with this event.
