A hospital room in Mountain View is full of joy tonight.
The Dolan's from Sunnyvale are gathered around 53 year old Lori Dolan.
Her heart stopped Sunday during the 49ers game.
In a panic her husband Larry called for their 17 year old daughter Lindsay.
Lindsay says when she saw her mom looked purple she knew she needed oxygen so she started CPR.
She says she took a one hour class at Fremont High School two years ago. Turns out it was a life saving class.
Doctors tell the Dolans, Lori didn't breathe for nearly 25 minutes and those first breathes delivered by Lindsay may have made the difference.
The high school junior is just getting used to being called a hero.
Mom and dad are proud.
Lindsay says, "It makes me feel amazing so much closer to her than I ever was it's crazy she's my mom I love her."
Doctors say Lori has Long QT syndrome. It's hereditary so now her sisters will be tested.
