You need to also have an emergency kit available that you can utilize with one hand.
It should be stocked with materials you can handle while you are alone and with the use of only one hand.
You don't want to be bleeding out, trying to make a call, then waiting 15 minutes for help to arrive, and THEN have to wait another 15 to get to the emergency room.
Don't get carried away with fancy bandages, just keep a couple thick sanitary napkins and a roll of gauze in your field box and you will be able to control even severe bleeding. I spent twenty years as an EMT and they they were always near the top of my jump kit. Unless you sever an artery, there isn't much bleeding that can't be controlled with pressure and elevation. Bleeding always looks worse than it is! As a last resort, there's always that handy bottle of CA that we all carry to make field repairs.
