Violent Asphyxial Death
- Asphyxia: Means mechanical interference with respiration; a Greek word meaning pulselessness

- Pathophysiology: Increased capillary permeability, increased intracapillary pressure, impaired venous return, and stasis
Tardieu's Spot
- Established by French police surgeon Tardieu in 1866
- Associated with violent asphyxial deaths
Types of Violent Asphyxial Death
