911 call shows Hayden Panettiere was given CPR on day she died

Zach Hickerson, the brother of Hayden Panettiere 's on-again, off-again boyfriend, Brian Hickerson, attempted CPR on the actress before she was declared dead , a 911 call revealed.
An autopsy found that Panettiere's death was accidental and ruled that the cause was the "toxic effects of" the drugs fentanyl, 4-ANPP, alprazolam, methocarbamol and quetiapine.
Zach Hickerson also told TMZ a few days later that Brian Hickerson gave Panettiere Narcan , a medication that can reverse opioid overdoses, after they found her unconscious.
