What do you do if blood does not stop flowing 4 minutes after a phlebotomy?

If blood does not stop flowing four minutes after a phlebotomy, apply firm pressure to the site with a clean, sterile gauze or cloth to help promote clotting. Elevate the arm above heart level to reduce blood flow to the area. If bleeding persists after a few minutes, seek medical assistance to evaluate the situation and provide appropriate care. It's important not to remove the gauze or apply excessive pressure that may cause discomfort.
