Alone in the darkness under layers of rubble (碎石) , Dan Woolley felt blood streaming from his head and leg.

Woolley, an aid worker, husband, and father of two boys, followed instructions on his cell phone to survive the January 12 earthquake in Haiti.

“I had an app that had pre-downloaded all this information about treating wounds. So I  looked up excessive bleeding and I looked up compound fracture(断裂),” Woolley told CNN.

The application on his iPhone is filled with information about first aid and CPR from the American Heart Association. “So I knew I wasn’t making mistakes, ” Woolley said. “That gave me confidence to treat my wounds properly.”

Trapped in the ruins of the Hotel Montana in Port-au-Prince, he used his shirt to bandage his leg, and tied his belt around the wound. To stop the bleeding on his head, he firmly pressed a sock to it. Concerned he might have been experiencing shock, Woolley used the app to look up what to do. It warned him not to sleep. So he set his phone alarm to go off every 20 minutes.

Once the battery got down to less than 20 percent of its power, Woolley turned it off. By then, he says, he had trained his body not to sleep for long periods, drifting off only to wake up within minutes.

With his injuries tended to, he wrote a note to his family in his journal: “I was in a big accident, an earthquake. Don’t be upset at God. He always provides for his children even in hard times. I’m still praying that God will get me out, but he may not. But even so he will always take care of you.”

After more than 60 hours, Woolley was pulled from the rubble.

“Those guys are rescue heroes,” he said to the crew that pulled him out.
