I took out some gauze and used it to apply pressure to the wound with my
index finger and thumb. So it was my
index finger on top, then the gauze, then his cut
finger, and then my thumb, if you saw it from top to bottom. His finger was bleeding profusely. Some blood may have soaked thru the gauze and come into contact with my finger, but I am not sure.
After I had sorted him out, i looked at my index finger and noticed some peeled cuticles around the nail. They did not appear to be bleeding.
