The event was assessed by subject matter experts (among others by customer complaint management (ccm), medical affairs (ma), product management (pm), regulatory affairs (ra), person responsible for regulatory compliance (prrc), quality management representative (qmr)).The event description is very poor.The end user did not respond to further enquiries and did not return the device for evaluation.Also, preventive maintenance has been overdue since october 2022.However, we cannot rule out the possibility that the reported event may be related to the removal action (b)(4) that has already been performed.The most probable root cause is a software inherent threshold at ~ 30 l inflow volume, which was originally intended to prevent data bit overflow between the scale and control unit pump.

We have been informed of the following event: "the fluid deficit dropped from 1700 to 0 instantly without having collected that amount from the underbuttox drape as there was none present at that time.(b)(6) was present in the room and the scales had not been touched, a canister was not being changed and a saline bag was not being hung at that time.The physician ended the case with the last recorded deficit of 1700 and chose not to move forward.Patient status: no injury reported, no extended hospital stay or additional treatment needed.Additional information: tech support is confirming the system is functioning correctly".
