What best describes positional asphyxia?

• A. The position of the body interferes with proper respirations
• B. External compression of chest only
• C. Loss of consciousness due to heat
• D. Psychological stress causes breathing faster

Answer: (A)

Positional asphyxia occurs when the body’s position itself prevents normal breathing. The way the torso, neck, or head is situated can restrict airway opening or limit chest expansion and diaphragmatic movement, leading to insufficient oxygen and rising carbon dioxide even without any external force directly crushing the chest. This concept matters because it highlights how restraint or awkward positioning can create dangerous breathing problems, especially in situations where a person is unable to move freely or is restrained. That makes the description about the body’s position interfering with respirations the best fit. The other options describe situations that don’t define positional asphyxia: external chest compression focuses on forceful squeezing, which may cause breathing issues but isn’t about the position itself; loss of consciousness from heat points to heat-related illness rather than breathing obstruction from posture; and stress-induced rapid breathing is a physiological response to anxiety, not a mechanical restriction of breathing due to position.
