Most people do not know the proper way to stop nosebleeds. The methods I hear about most often include putting a cold compress on the bridge of the nose, leaning forward, or having the child tilt his head back so his nose is pointing up in the air. The reason such remedies abound is because people do not realize that 95% of the time, the bleeding is coming from the nasal septum (this is the name of the cartilage that separates your nostrils).
The best way to stop bleeding is to put direct pressure on the area that is injured. Therefore, the way to stop a nosebleed is to pinch someone’s nostrils with medium pressure for five minutes without peeking. Once the bleeding stops, ask your child to refrain from picking or blowing his nose because that would dislodge the clot and the bleeding could start again.
If your child’s nose continues to bleed after five minutes of constant pressure, repeat the pinching procedure for ten minutes. If that does not work, call your doctor.
