Bleeding

Bleeding can be visible (cuts, nosebleeds, vaginal, GI) or hidden (internal). Severe bleeding is a medical emergency requiring immediate action.

Quick Facts

  • ICD-10: Various

When to Call 911

Call 911 for:
  • Bleeding that won't stop with direct pressure
  • Vomiting blood or coughing up large amounts of blood
  • Black or maroon stools, especially with weakness
  • Heavy vaginal bleeding (soaking pad in <1 hour)
  • Bleeding with severe abdominal or chest pain
  • Bleeding in someone on blood thinners after head injury
  • Signs of shock — pale, sweaty, fast heart rate, fainting

First Aid for External Bleeding

  1. Apply firm direct pressure with clean cloth or hand
  2. Elevate the area if possible
  3. Don't remove cloth — add more on top if soaked
  4. For severe limb bleeding, tourniquets are recommended if direct pressure fails (and emergency care isn't immediately available)
  5. Keep the person warm; lie them down if faint
