Event Description
|
While troubleshooting an "error 5" message on the coaguchek meter the reporter mentioned that 2 years ago, he was allegedly unable to test on his meter due to an error and allegedly had a brain bleed a few days later.The exact date was unknown by the reporter.Based on this information the date of the event is an estimate.The reporter could not recall the error message he received 2 years ago.After a few days of not being able to test, the reporter stated that he went to the emergency room "due to a brain bleed".His inr result at the hospital from an unspecified source was reported to be 12.5.He stated that he did not receive any medical treatment while at the hospital and was sent home.The next day, the reporter stated that he was found to be in a coma at home and was care flighted to the hospital.He stated that he did not receive any medical treatment and was sent home.He further stated that he permanently has brain and speech damage due to the brain bleed.The patient's therapeutic range was reported to be 2.5-3.0 inr and testing is performed weekly.This mdr is being submitted in an abundance of caution.
