- Fluid loss resulting in decrease of intravascular volume
Nota:
- Traumatic hemorrhage: Long bone/pelvic fx, solid organ rupture, major vessel disruption, open wounds. Nontraumatic hemorrhag: GI bleed, ruptured AA, ruptured ectopic pregnancy, epistaxis, OB hemorrhage, DIC

- Remember ABCs. O2 via NRB if conscious, ET if unconscious. Sp02 and ABG. Stop bleeding
(pressure, dressing, splints, OR etc.). 2 large bore IV with isotonic crystalloids (LR/NS) -
warm to prevent hypothermia and metabolic acidosis. Draw labs, including type/crossmatch. NG, foley, monitors.
- Classified stages I-IV
