Study Notes
Definition and Classification of Asphyxia
- Asphyxia is a forensic term referring to the lack of oxygen in the body, resulting in death
- Classified into four categories: suffocation, strangulation, mechanical asphyxia, and drowning
Causes of Asphyxia
- Partial oxygen deprivation (hypoxia)
- Total oxygen deprivation (anoxia)
Phases of Asphyxia
- Not specified in the text, but generally includes stages such as congestion, cyanosis, and tetany
Signs of Asphyxia
- Cessation of respiration inside the cell and failure of the respiratory process
- Can be a result of sexual assaults, making it essential to examine asphyxia victims for possible sexual abuse
Importance of Asphyxia in Forensic Science
- Asphyxiation, specifically strangulation, is the most common cause of death in human sexual assaults
