One double pressure tubing kit with an attached merit flush device and iv set was returned for examination.The reported event of flow rate issue was not able to be confirmed during the evaluation.A general examination was performed to the returned sample.As received into the laboratory, all connections appeared tight.No visible defect was observed from the kit.The device was able to prime throughout the kit without indication of occlusion or flow restriction.However, the flow speed was visually faster on the red line than on the blue line even when fast flush was not activated with pulling the snap tab or squeezing the actuator.No leakage was observed from the kit during leak test.The flow rate could not be measured during evaluation since edwards evaluation procedure was not applicable for flow rate testing of the merit flush device.The flush device will be sent to merit to conduct a flow rate test of their device.Invasive procedures involve some patient risks.Although serious complications are relatively uncommon, the physician is advised, before deciding to use the system, to consider the potential benefits in relation to the possible complications.These products are used by highly trained clinicians, experienced in identifying and mitigating any hazards that arise during use.In addition, these devices are typically used in intensive care units or operating rooms, where patients are closely monitored.In this case it was noted that there was no patient compromise.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.
