Friends and family are rallying around a 16-year-old girl who is lucky to be alive after suffering a heart attack before she sat a Perth high school exam earlier this month.
Telita Calley, a student at Kingsway Christian College, was about to take her year 11 exams when a boy at her school asked her to the school ball.
"I had just been asked to the ball by this guy and I collapsed," she told 9 News Perth.
"I grabbed my friend's hand because I was so excited, and then I just kind of collapsed.
"She stopped my head from hitting the ground."
Telita's face began to turn blue due to a lack of oxygen and she soon went into cardiac arrest.
Her mother Julianne Calley credits her daughter's survival due to the quick thinking of her fellow students, who put her into the recovery position and began CPR.
"They just did everything perfectly," she said.
Kingsway college teaches CPR and First Aid in its cadets program, and students and teachers put them to good use, keeping Telita alive while her twin brother Joel ran to get their father Marty - an employee at the school.
Marty was able to provide Telita with his scuba-diving cylinder, which he used to administer her oxygen. Telita was in cardiac arrest for around 20 minutes, but remarkably suffered no brain damage.
She now has a defibrillator surgically fitted to her heart, and a GoFundMe has been set up to help the Calleys with the costs associated with her treatment.
"I would have died. I wouldn't be here today and I wouldn't be talking," she said.
