Shock Definition |
Clinical manifestation of the bodys inability to perfuse its tissue adequately
|
|
|
4 Types of Shock |
Hypovolemia Cardiogenic Distributive Obstructive
|
|
|
For every 1CC of blood loss need to replace with ___ CC of Isotonic (NS or LR) |
3CC of NS or LR
fluid lost to third spacing and leaves intravascular
|
|
|
Cardiogenic Shock : Causes, Result, |
Causes ; CHF, valvular failure, Toxins, Chest trauma, MI(LV failure) Result : decreased cardiac output
|
|
|
Cardiogenic Shock : Goal |
Goal : maximize cardiac output while reducing workload of hear muscle. Do by maintaining adequate preload(Lasix will decrease), Decrease afterload (pressure the heart has to pump against) (Nipride, vasodilatior, ace inhibitor), Increase contractility(2nd to decreasing afterload)(dopamine, dobutamine) |
|
|
Distributive Shock Description |
Blood is maldistributed to the periphery. Increased parasympathetic control of heart. Dilated resting vessels |
|
|
Distributed Shock Types (3) |
Neurogenic Septic Anaphylaxis |
|
|
Distributive Shock : Neurogenic |
Loss of sympathetic outflow(epi and norepi). Typically T6 area. Warm and dry below injury Bradycardia or normal heart rate. |
|
|
Obstructive Shock : Description, Causes |
Inadequate circulating blood volume due to compression of great vessels or hear. Causes : cardiac tamponade, aortic aneurysm, tension pneumothorax, pulmonary embolism |
|
|
Assessment of patency of IO |
Aspirate for bone marrow(but does not mean it is not patent)
Best = does NS flow via gravity |
|
|
Cardiac Tamponade : signs |
Becks Triad : decreased BP, muffled heart tones, JVD.
|
|
|
Becks Triad |
Decreased BP Muffled Heart Tones JVD
