Open wound bleeds each round: lose the source's bleed amount at start of turn.
A hemorrhaging character has a wound that will not close on its own -- an
arterial hit from a monomolecular blade, a wire-slash from a board, a bite
that keeps bleeding. At the start of each of their turns they lose the bleed
amount set by the source (typically 1d4 HP, or a fixed value for severe
wounds) until the flow is stopped. The bleeding ends with a successful
Medicine check (DC 15, standard action by self or adjacent ally), with any
healing or stim effect, or with a Fortitude save at the start of the turn
(DC = source's bleed DC, default 15) as the body clots on its own. This is
the ongoing-damage wound state; it is distinct from the Bleeding condition
(Bleeding (Unconscious at 0 HP)), which is the unconscious, dying-at-0-HP death state.
