Resource summary

Hypovolemic Shock
  1. Fluid loss resulting in decrease of intravascular volume

    Annotations:

    • 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
    1. ▼ Cardiac output
      1. ▼ Tissue perfusion
        1. Compensatory Mechanisms Activated
          1. Epi/Norepi release
            1. ▲ HR and systemic vascular resistance
            2. Renin-Angiotesin-Aldosterone & ADH release
              1. Intracellular fluid shift to intravascular space
                1. ▲ Blood volume
                  1. ▲ Cardiac output
                    1. Compensatory Mechanisms Fail

                          1. ▼▼▼ Vital organ perfusion
                            1. Multisystem Organ Failure
        2. 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.
        3. Classified stages I-IV
