What are 3 types of circulatory shock?

1. Hypovolemic shock:

Causes:

- Hemorrhage: loss of blood from the circulatory system

- Fluid loss: excessive fluid loss (e.g., dehydration, burns, diarrhea, vomiting)

Effects:

- Decreased circulating blood volume

- Low blood pressure

- Rapid heart rate

- Cold, pale, clammy skin

- Decreased urine output

2. Cardiogenic shock:

Causes:

- Heart attack

- Heart failure

- Severe arrhythmias

Effects:

- Sudden decrease in cardiac output

- Low blood pressure

- Fast or weak pulse

- Confusion or disorientation

- Shortness of breath

- Fluid retention

3. Distributive shock:

Causes:

- Sepsis: severe systemic infection

- Anaphylaxis: severe allergic reaction

- Neurogenic shock: dysfunction of the autonomic nervous system

Effects:

- Vasodilation (widening of blood vessels)

- Decreased blood pressure

- Increased heart rate

- Warm, flushed skin

- Rapid breathing
