Exposure from performing CPR? - TheBody.com's Bulletin Boards

A few nights ago I was out with a friend and we were walking down the street when we noticed a couple of people standing in the middle of the road a bit down the way. When we got closer we realized there was another person lying on the road. Apparently this person was extremely intoxicated and had been saying he was hit by a truck but when we got there he was no longer breathing. A fifth person joined and said he was an EMT and I joined in assisting him with CPR. At first, I started with chest compressions and he did mouth to mouth, but as I am a small female I couldn't compress quite hard enough so we switched. I only managed a few breaths before we saw the ambulance heading up the road.

I am a very anxious person when it comes to diseases of any kind, a bit of an admitted hypochondriac, but I am wondering what my possible risk of exposure to HIV might be. This was a stranger and I have no idea of his lifestyle, risk of infection, etc. There was no visible blood that I could see, but it was night. Also, I have a canker sore just inside my lip from biting it a couple days prior, though it was not actively bleeding. Is this considered an open wound? Though I do plan on visiting my doctor in the next couple days, I was just looking for some answers in the meanwhile. I'm a mom to a toddler and am terrified at the thought that I may have put myself at risk, irrevocably changing both of our lives forever.
