Is net flow of fluids in or out of vessels?
What removes this fluid?
Out
Lymphatics
What are the three causes of increased outflow of fluid from vasculature?
-Leaky vessels
-Decreased intravascular albumin
-Increased hydrostatic pressure

Pulmonary
Cause it's a lower pressure system and bigger fenestrations
What is the formula for total tissue blood flow?
Mean arterial BP - central venous pressure / resistance

Hypovolemic ex. Hemorrhage, severe dehydration

Vasodilatory ex. Inflammatory mediators, drugs, toxins, neurogenic

Cardiogenic ex.Drugs, inflammatory mediators, heart disease

Obstructive ex.GDV
What is shock?
Decrease O2 delivery to tissues based due to decrease in blood flow
What is the best way to treat hypovolemic shock?
Vasodilitory?
fluids

vasopressors such as epinephrine
What is the best way to treat cardigenic shock? Obstructive?
Positive inotropes, diuretics, vasodilators
Remove cause of blockage
What are the three stages of shock?
1) Compensated
2) Early Decompensated
3) Decompensated
What are clinical signs of shock?
Increased heart rate, weak pulses, dull, decreased urine output, pale gums, prolonged CRT
What is SIRS? What is sepsis?
Systemic inflammatory response syndrome
If SIRS is caused by an infection
