Don't reach for bandaids unless it's a minor cut or scrape.

Reach for 1.Non-stick Telfa Pad, apply 2.Coban, wrap it snug (end of finger should capillary refill)3.Keep the pressure on.

Once hemostasis is achieved, goto a clinic to see about stitches, debridement, prophylactic antibiotics, etc.

I'll never forget one guy who came in with his bone visible and was wondering if he should go see one of the docs in our clinic...!?
