Learning the difference between a snore and a "Death rattle" is the difference in life or death. Terminal Secretions occur during an overdose or fentanyl poisoning. Saliva and mucus pool in the back of the victims throat, but the substance prevents the individual from controlling their throat muscles. The result is air trying to break through the pool and creating a gargling rattle. If you identify this noise, call 911 immediately. #overdoseawareness #FentanylDangersAreReal #wedorecover #recover
