It was a simple medical appointment that put petty officer Linda Hayden on this road -- exactly when and where she was needed.

Linda is based in Everett, but was on her way to Naval Hospital Bremerton for some bloodwork and a flu shot when she saw a vehicle off the road, with the wheels still spinning. She ran up to the SUV and saw a woman inside.

Linda said, "She was hunched over. Seatbelt was over her neck and stuff. She wasn't breathing. So I immediately yelled for them to call 911. Got her out of the vehicle started doing CPR. She had no pulse, nothing."

Ron Lewis, who witnessed the situation, said it was very serious and even life-threatening.

"If petty officer Hayden hadn't been there, I'm not sure what would have happened exactly."

When Linda started CPR, the woman started having a seizure and kicked her in the ribs. The kick was so hard it actually broke one of Linda's ribs.

But Linda did not stop working.

The woman she was helping was in uniform -- she was a sister-in-arms.

"I got to save a sister's life."

Paramedics arrived and took over. Linda later heard the woman was alright.

Her takeaways?

"Do the right thing. You see someone in trouble, no matter what. I mean, joining the military, everyone else's life is more important than mine. I don't care who you are. I'm going to do whatever I can to save you."

If you would like to get certified in CPR, you can find classes on the American Red Cross' website.
