| What are the three characteristics of shock? |
|
Definition
1. Hypoperfusion
2. Inability to provide adequate blood flow for organs to fxn
3. O2 Demand > Supply |
|
|
Term
| Perfusion of organs depends on ______ output and ________ vascular resistance. |
|
Definition

|
Term
| What are the five types of shock? |
|
Definition
LOW BLOOD FLOW (Cardiogenic, Hypovolemic)
Maldistribution (Sepsis, Neurogenic, Anaphylactic) |
|
|
Term
| Characterize Neurogenic shock (Maldistribution) |
|
Definition
| Loss of neural control over vaso constriction |
|
|
Term
| Characterize Septic Shock (maldistribution) |
|
Definition
| infection causes vascular permeability problems. |
|
|
Term
| Characterize Anaphylactic Shock: |
|
Definition
| Increase permeability from histamines, volume escapes vasculature and hypoperfusion ensues |
|
|
Term
| Characterize Cardiogenic shock |
|
Definition
|
|
Term
| What are the two main hemodynamic effects of ALL types of shock? |
|
Definition
| Decreased Pulse Pressure nad Decreased Blood Pressure |
|
|
Term
| Vaso_______ and increased vascular permeability are the main problems in maldistribution types of shock. |
|
Definition
|
|
Term

|
Definition
| Neurogenic (think drug induced) |
|
|
Term

|
Definition
| Cardiogenic and Hypovolemic |
|
|
Term

|
Definition
|
|
Term
| Which type of shock has increased cardiac output? |
|
Definition

|
Term
| What are the three stages of shock? |
|
Definition
Compensatory (compensating)
Progressive (declining)
Refractory (irreversible damage) |
|
|
Term
| What are the signs in Compensatory Preshock? |
|
Definition
Increases in HR, RR, Blood Glu
Decrases in PaO2 and PaCO2 |
|
|
Term
| What are the signs of going into Progressive Shock? |
|
Definition
Decreases in CPP and BP
MAP <60
Pulmonary Edema
GI bleeding/ischemia
Liver Impaired |
|
|
Term
| What are the signs of refractory shock? |
|
Definition
Decreased urine output
Increased BUN/Cr
Hypothermic
Cold/Clammy
Lactate, bleed time, liver nz's |

ABC
IV access
Indwelling catheter
NG tube to continually remove stomach contents |
