Episode notes
Defining Shock Accurately
- Shock is defined as inadequate oxygen delivery compared to oxygen consumption causing organ dysfunction.
- It is not synonymous with hypotension or defined by a single lab value.
Oxygen Delivery Components
- Oxygen delivery depends on blood oxygen content and cardiac output.
- Stroke volume, heart rate, and hemoglobin saturation critically affect oxygen delivery.
Rapid Shock Assessment
- Quick bedside assessment including mental status and capillary refill can detect shock within seconds.
- Altered mental status in shock signals worse prognosis and demands urgent attention.
