RIDGEWOOD, N.J. (CBSNewYork) – It was a single phone call that made the difference between life and death.

The caller was a 5-year-old New Jersey girl. The child dialed 911 after her mother began choking and couldn’t speak, CBS 2’s Vanessa Murdock reported Wednesday.

Chloe Olson did the remarkable.

“Because it was an emergency,” she said Thursday.

Her mother, Kerry Olson, was choking on chip on Tuesday inside the family’s house in Ridgewood.

“I must have covered my windpipe. I was choking and coughing but mostly I couldn’t get any air,” Kerry Olson said.

“I heard her coughing,” Chloe added.
