A review of the device's manufacturing records revealed that the sensor lot met all requirements including sterilization requirements for release.A subcutaneous pocket of 3mm - 5mm deep will be created under the skin and the sensor will be inserted in this pocket.If the insertion pocket is too deep and if the sensor is inserted, this would result in inconsistent or weaker connection with the transmitter, affecting the normal functioning.In this incident, the sensor was inserted on 13 november 2023 and since then the patient received "no sensor detected" alerts very often.The issue started immediately after insertion.When the customer tries to establish the connection the placing the transmitter over the insertion area by following placement best practices, the connection loses upon making hand movements.The issue was escalated and a review of transmitter diagnostic log revealed a weaker signal strength between the sensor and the transmitter.It was determined that the sensor was inserted deeper than usual.The customer was recommended to consult with hcp regarding the removal of sensor.The most likely root cause of the issue is the procedural error from the inserting doctor.This incident does not require any further investigation.
