Positional asphyxia occurs specifically when the positioning of the body restricts airflow, making it difficult or impossible for an individual to breathe properly. This often happens in circumstances where a person's body is placed in a position that compresses the chest or constricts airflow to the lungs, such as being pinned down or trapped in a way that limits their ability to expand their chest or move their diaphragm. This definition highlights the direct link between body position and the ability to breathe, which is central to understanding how positional asphyxia can arise in various situations, particularly in security-related incidents where restraint may be involved.

While some of the other options touch on aspects related to breathing difficulties or mobility, they do not encapsulate the specific relationship between body position and respiratory function as clearly as the definition of positional asphyxia does.
