types of shocks

concept

100

preload

Preload, measures the degree of the ventricular stretch when the heart is at the end of diastole. It is the amount of blood that returns to the heart from veins ( vein return )

200

afterload

It is the resistance against which the ventricles contract.

300

SVR 

It refers to the resistance to blood flow offered by all the blood vessels in the systemic circulation (excluding the pulmonary circulation)

400

Cardiac output 

Cardiac output (liters/minute, cc/min): amount of blood ejected from the ventricle in a minute.

500

stroke volume

Stroke Volume = mL/beat; amount of blood ejected from ventricle in one beat

normal value

100

cardiac output 

4 to 6 L/min

200

MAP

70-110 mmhg 

300

SV 

60-90 cc

400

heart rate 

60-100 beats/min 

500

CVP 

2-6 mmhg

shocks

100

shock

A life-threatening condition, characterized by inadequate tissue perfusion

200

Anaphylactic shock 

—Acute syndrome. Due to sudden release of mast cell- and basophil-derived mediators into the circulation

300

cardiogenic shock 

Cardiogenic shock is a life-threatening condition where the heart is unable to pump enough blood to meet the body's needs

400

5 causes of cardiogenic shock 

myocarditis/ endocrditis/ Heart attack/ valvular dysfunction/ heart failure 

500

stages

Initiation/ Compensatory stage/ Progressive stage/ Refractory stage.
