📋 3️⃣ Memory Tables
Table 1 — Comparison of Shock Types
| Shock Type | Main Defect | Typical Feature |
|---|---|---|
| Hemorrhagic | Blood loss | Cold clammy skin |
| Cardiogenic | Pump failure | Pulmonary edema |
| Neurogenic | Loss of sympathetic tone | Bradycardia |
| Anaphylactic | Histamine release | Wheezing + edema |
| Septic | Severe infection | Warm flushed skin |
Table 2 — Stages of Shock
| Stage | Main Feature | Reversibility |
|---|---|---|
| Compensated | Reflex compensation active | Reversible |
| Progressive | Tissue hypoxia worsening | Difficult |
| Irreversible | Organ failure develops | Poor prognosis |
⚡ 4️⃣ Rapid Revision Points
Must Remember:
• Shock = inadequate tissue perfusion.
• Lactic acidosis indicates tissue hypoxia.
• Sympathetic activation causes tachycardia.
• Hemorrhagic shock reduces venous return.
• Cardiogenic shock causes pulmonary congestion.
• Neurogenic shock may cause bradycardia.
• Septic shock initially causes warm skin.
• Histamine mediates anaphylactic shock.
• Oliguria reflects poor renal perfusion.
• Vasopressors increase vascular tone.
• Irreversible shock leads to organ failure.
• Early treatment improves survival.
