(CNN)With 30 compressions and two rescue breaths, 16-year-old Torri'ell Norwood saved her best friend's life, just a day after completing a basic life support class at her high school.
Just one day after completing CPR training, a teen saves her friend's life
"I never would have thought that I would be the one, out of all the students in my class to have to perform it on someone," she said.
Norwood was driving three friends home in St. Petersburg, Florida, on February 20 when another driver slammed into her from her left and sent her car careening.
"We crashed in someone's yard and I hit the tree," Norwood said.
The impact jammed shut the driver's side door, so Norwood climbed out the front window. Two of her friends managed to get out of the car unharmed, but the collision caused her 16-year-old friend A'zarria Simmons to hit her head on the backseat window.
"When I turned around, I didn't see A'zarria running with us," Norwood told CNN. "So, I had to run back to the car as fast as I can. She was just sitting there unresponsive."
And that's when the training Norwood had just learned kicked in.
"A lot of people started to gather around to see what was happening. I started yelling, 'Back up, back up, she needs space.'"
She pulled Simmons out of the back seat, avoiding broken glass from the window.
"That's when I checked her pulse on her neck. I put my head against her chest, and I didn't really hear nothing. So that's when I just started doing CPR on her."
After the 30 compressions and two rescue breaths, Simmons regained consciousness. Paramedics quickly arrived and rushed her to the hospital, where she received stitches for a gash in her forehead.
"I don't remember the hit or anything about accident. But when I woke up, I was in the hospital. I was in shock. I was trying to figure out how I got there," Simmons said.
Norwood, a junior at St. Petersburg's Lakewood High School, participates in the school's Athletic Lifestyle Management Academy. The program prepares students for various careers in health science.
"We do vital signs and they learn how to take blood pressure and check pulse. We have just about 100 students in our academy," Erika Miller, Norwood's instructor, told CNN.
