A
Decreased energy production Deterioration of cellular function Excess production of lactic acid Eruption of intracellular lysosome Cell death
4
Q
Classifications of Shock
A
- Distributive: Neurogenic, Anaphylactic, Septic
- Hypovolemic
- Cardiogenic
- Obstructive
5
Q
Distributive Shock
A
Decreased vascular tone
- Neurogenic
- Anaphylactic
- Septic
6
Q
Hypovolemic Shock
A
Body fluid depletion
7
Q
Cardiogenic Shock
A
Pump failure
8
Q
Obstructive Shock
A
Blood flow obstruction that leads to decreased CO
9
Q
Shock Focus of care
A
- Identify pts at risk
- Integration of pts hx and PA to make dx
- Tx and eliminate cause
- Monitor tissue perfusion
- Protect target organs from dysfunction
- Multisystem support care
10
