How to Stop Bleeding
All bleeding is stopped in the same way, with constant pressure. So whether its a nosebleed, or a laceration, whether it is an even stream of blood from a vein, or a pulsing spurt from an artery, constant pressure must be applied to control the bleeding. Do not wipe, and do not remove the pressure to see if the bleeding has stopped. If the wound is large, you can pack the wound with whatever you have available such as clean gauze or cloth, and then wrap a tight pressure dressing around the wound. In severe 
bleeding where blood loss can be profound, you can first apply a torniquet while you pack and dress the wound. The tourniquet time should be a maximum of about 20 minutes, and you may have to release and reapply the tourniquet while en-route to the hospital.
Blood clots by way of little plugs called platelets. The platelets need something to hang on to, or else they will simply continue to free flow out of the would with the rest of the blood. By applying pressure, you give the platelets a sort of backstop to adhere to. If you continue to remove the pressure to look to see if the bleeding has stopped, you in effect tear the scab off.
I never knew that the reasoning behind pressure was for the platelets. I love learning new things!
