(b)(4). Diabetes mellitus is a known cause of hypoglycemia and loss of consciousness.
 
Event Description
Dexcom was made aware on (b)(4) 2018 that on (b)(6) 2018, there was an inaccuracy between the continuous glucose monitor (cgm) and the blood glucose (bg) meter. The sensor was inserted into the arm on (b)(6) 2018. The patient's father stated the patient fainted and was provided 4 units of glucagon. He indicated that the patient recovered immediately. It was reported that the cgm was displaying 5. 2 mmol/l, compared to a finger stick reading of 1. 7 mmol/l. At the time of contact, the patient was doing fine. No additional event or patient information is available. No data was provided for evaluation. The complaint confirmation and root cause could not be determined. The sensor was inserted into the arm. Labeling indicates: do not insert the sensor in sites other than the belly (abdomen) or upper buttocks. Use in other sites might cause sensor glucose readings to be inaccurate and could result in you missing severe hypoglycemia (low blood glucose) or hyperglycemia (high blood glucose) events. It was reported that the patient did not calibrate after the inaccuracy. Labeling indicates: if the difference between your sensor glucose reading and blood glucose value is greater than 20% of the blood glucose value for sensor glucose readings > 80 mg/dl or greater than 20 points for sensor glucose readings < 80 mg/dl, wash your hands and take another blood glucose measurement. If the difference between this second blood glucose measurement and the sensor is still greater than 20% for sensor glucose readings > 80 mg/dl or greater than 20 points for sensor glucose readings < 80 mg/dl, recalibrate your sensor using the second blood glucose value. The sensor glucose reading will correct over the next 15 minutes.
