TMZ has obtained the dispatch audio from Canton Township Police following the emergency call made in August ... and the unnamed caller repeatedly asks law enforcement to "hurry up" as they performed CPR.

After dispatch guided them through the life-saving procedure ... the caller asks someone else in the home to open the front door before neighbors arrived to help.

At one point, the caller admits he can't give chest compressions forever.

When paramedics eventually arrived and took over performing CPR ... the family member called out to the first responders ... "I'm here. Please hurry, please."

As we reported ... the porn star's cause of death was listed as alcohol and mitragynine toxicity. Mitragynine is the primary active compound in kratom, an over-the-counter herbal product used for energy and pain relief.
