Resource summary

Shock Stages
  1. Initial/Early
    1. Slight change to MAP (5-10mm Hg)
      1. ▼ cardiac output (15%)
        1. Slight ▲ HR
          1. Switch from aerobic to anaerobic metabolism
            1. ▲ lactic acid
            2. Compensatory
              1. Activation of compensatory mechanisms
                1. Tachypnea, tachycardia, vasoconstriction
                  1. ▼ MAP (10-15mm Hg)
                    1. Continued ▼ cardiac output (15-30%)
                2. Progressive
                  1. Compensatory mechanisms fail
                    1. Hypoperfusion
                      1. ▼ cardiac output (30-40%)
                        1. ▼ cardiac perfusion/contractility
                          1. ▲ Ischemia of non-essential organs (kidneys, intestines, skin)
                            1. ▲ capillary permeability
                              1. ▲ HR, weak/thready pulse
                            2. Refractory
                              1. Irreversible cell/tissue/organ death
                                1. MODS
                                  1. Severe hypoxemia
                                    1. Renal failure
                                      1. DIC
                                        1. Circulatory failure
