1. Be sure the patient is seated upright with the head above the level of the heart and shoulders.
2. Gently blow each nostril to be sure there are no large blood clots inhibiting the nosebleed from clotting.
3. With the thumb and first finger, firmly pinch the nose just before the bone, that is, the bridge of the nose, fully occluding both nostrils. Hold firmly for 3 to 5 minutes to encourage the bleeding spot to clot.
4. Release and repeat steps two and three if there is still ongoing bleeding.
5. If bleeding continues, try applying a nasal decongestant like Neo-Synephrine or Afrin to the side that appears to be bleeding, then reapply pressure.
6. Sometimes, by holding an ice cube directly underneath the upper lip, you can shrink the blood vessels that might be involved in the bleeding and help control the bleeding.
If none of these steps help stop the bleeding, consult your primary care doctor or seek medical assistance at an urgent care or emergency department.
