  1. Positional Asphyxia MVA Training The Spinney

  2. Positional Asphyxia The term asphyxia is vague and confusing. Refers to a state of the body: • Deprived of Oxygen • Excess carbon dioxide • Hypoxia

  3. Positional Asphyxia • Loss of consciousness • Low oxygen • High Carbon dioxide • Asphyxia – achieved unnaturally

  4. Positional Asphyxia • Physical energy expenditure • Increasing body chemicals • Weaken body muscles • Respiratory muscles

  5. Positional Asphyxia • Stress on heart increases • More oxygen to function If an individual with severe respiration muscle fatigue is restrained in a position that impairs or prevents breathing, it is easy to understand why positional asphyxia can occur so quickly.

  6. Positional Asphyxia • Syndrome (traumatic asphyxia) • Sole/contributory factor to death • Breathing apparatus impaired • As a result of restraint

  7. Risk Factors • Position during restraint • Prolonged struggle • Prescribed medication • Respiratory disorders • Drug and alcohol intoxication • Cardiovascular disorders • Obesity

  8. How to asphyxiate • Compression to neck • Compression to chest/back/torso • Obstructed airways/vomiting • Chemical/environmental • Postural position

  9. Signs • Congestion of the face • Facial oedema • Cyanosis/increased de-oxygenated blood

  10. Awareness • Observations • Vital signs • Overheating/dehydration • Caution with administering medication
