How many finger should you be able to insert under an emergency bandage once its been applied?

Once an emergency bandage has been applied, you should be able to fit one to two fingers underneath it. This ensures that the bandage is secure enough to control bleeding while still allowing for circulation and preventing excessive pressure on the wound site. If you can fit more than two fingers, the bandage may be too loose, and if you can't fit a finger, it may be too tight and could compromise blood flow.
