WINONA, Minn. (WKBT) -

Winona residents received a free lesson in how to save lives Saturday.

Winona Health Hospital held eight classes to teach hands-only CPR. Nearly 100 people took part in the sessions at the clinic. Experts say the simple technique can mean the difference between life and death.

"It's often the bystanders that are there first on the scene, and if they know what to do and have the confidence and courage to step forward, we can reduce the chances of a person surviving two or three times over,” said CPR instructor Helen Bagshaw.

Experts also say for every minute that passes and nothing is done for a victim, the chances of survival reduce by 10 percent.

This is the first of two hands-only CP-R sessions in Winona this year.
