well...this is what i found...
"While many healthcare providers know that applying digital pressure to the nasal arteries will help stop the bleeding, there is confusion about exactly where to apply that pressure. The correct location is below the nasal bones, on the ala nasi (see Figure 1). Applying pressure in this area will compress arteries in the anterior portion of the nose in the region of Kiesselbach's plexus, also called Little's area—the most common site of nosebleeds.
Keep the patient's head up and tilted slightly forward while pinching the nostrils together with your thumb and index finger. Apply firm pressure for at least five minutes and possibly for as long as 30. You can also place ice compresses over the middle of the face to promote vasoconstriction.
In order to keep blood from draining into the nasopharynx, have the patient stay in an upright position. If he lies down, he could aspirate blood or swallow it and then vomit.
Tell the patient not to blow his nose, but rather to allow the blood to ooze on its own. If blood is in the patient's mouth, have him expectorate in an emesis basin.
Since blood particles may become aerosolized with coughing or sneezing, wear eye protection, gloves, a mask, and a gown when working with these patients."
...so i guess that means down...
