If someone is having a nosebleed, your priority is to control the bleeding and keep their airway open.

Get them to sit down (not lie down) as keeping the nose above the heart will reduce bleeding.

Get them to lean forward (not backward), to make sure the blood drains out through their pause every ten minutes until the bleeding stops.

Encourage them not to speak, swallow, cough, spit or sniff because this may break blood clots that may have started to form in the nose.

If the bleeding is severe, or if it lasts more than 30 minutes, call for medical help.
