DENVER (KDVR) — Authorities are calling an 8-year-old girl a hero after her calm 911 phone call saved her father, who was suffering from a medical emergency on Sunday.

South Metro Fire Rescue said 8-year-old Adriana was settling in for the night with her father, John, on Sunday when he had a seizure and became unresponsive.

Adriana later recounted to the fire rescue agency that her father was shaking, and she sprang up from the couch. She used Siri to call 911, and the fire rescue said she was able to calmly give the phone number, house address and her father's medical status during the emergency.

Parts of the 911 call were posted on SMFR's Facebook, in which Adriana said her father mumbled something, then started shaking. She told dispatchers her father was snoring, and she was able to help dispatchers figure out if he was breathing.

"This call was, was exceptional, I've never had a call where an 8-year-old was so calm, and her demeanor was so, just level-headed. It was amazing," said Steve Smith, the emergency communications dispatcher.

Smith said he "couldn't believe" it was a child making the call, as it was one of the smoothest calls he's ever had.

The fire rescue included interviews with the family in the video, where John said he had brain cancer, and this was his first seizure. He said he tried to tell Adriana to call 911, but he lost his voice. John said Adriana's actions may have been life-saving.

"My wife and I are both previous military police officers, I'm a previous DOD firefighter, so to know that we are raising our daughters so that they can be, you know, so they can respond appropriately, and that they can handle a situation, that I'm sure is extrememly scare for an 8 year old, and do such a wonderful job, means so much to me as a father," John said.

The fire rescue said John was released from the hospital later on Sunday, and he is now back at home and doing well.

The agency said this is a reminder to teach kids how to call 911, and to make sure they know their phone number and address, have a family emergency plan and designate a meeting place outside your home.
