Which type of asphyxia occurs when an external object inhibits normal chest function?

• A. Drowning
• B. Positional Asphyxia
• C. Mechanical Asphyxia
• D. Shaken-Infant Syndrome

Answer: (C)

Mechanical asphyxia occurs when an external object or force restricts or obstructs the normal functioning of the respiratory system. This can include situations where an object applies pressure on the chest or body, preventing the lungs from fully expanding or contracting, which is essential for effective breathing. Examples of mechanical asphyxia include scenarios such as being pinned down by a heavy object or being in a tightly confined space where movement is restricted. Other types of asphyxia, such as drowning, involve the inhalation of water that blocks the airways, leading to suffocation. Positional asphyxia refers to circumstances where an individual's position—such as being trapped or wedged in a way that impedes breathing—causes asphyxia due to the angle or pressure on the body but does not necessarily involve a direct external object in the same way. Shaken-Infant Syndrome is a form of child abuse that leads to brain injury and does not pertain to asphyxia in the context of respiratory obstruction from an external source.
