The injured character must make a Vigor roll at the start of each round after the one in which he was injured and before Action Cards are dealt:
Other characters may stop a victim's bleeding by making a Healing roll. If successful, the victim stabilizes immediately and no further rolls are required. This use of the Healing skill just stops the bleeding. See page 87 for the use of the Healing skill to recover actual wounds.
