What term describes death from restraint where the body's position interferes with breathing?

• A. Positional restraint asphyxia
• B. Mechanical asphyxia
• C. Thermal asphyxia
• D. Cardiac-related asphyxia

Answer: (A)

Positional restraint asphyxia describes death that occurs when a person’s body position during restraint interferes with breathing. Asphyxia means not getting enough oxygen, and in this scenario, the way the body is held—often face-down with torso or chest compressed, or the head and neck positioned in a way that restricts airway patency or chest expansion—prevents normal air exchange. With the chest and diaphragm limited in their ability to expand, oxygen intake drops, leading to hypoxia and potentially death if the position is maintained. This term specifically points to the restraint situation and the role of body position, unlike mechanical asphyxia, which is about external forces or objects directly blocking air flow, or thermal asphyxia and cardiac-related asphyxia, which involve heat-related effects or heart problems rather than the restraint-induced breathing limitation.
