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

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

Positional Asphyxia Physical energy expenditure Increasing body chemicals Weaken body muscles Respiratory muscles

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.

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

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

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

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

Awareness Observations Vital signs Overheating/dehydration Caution with administering medication
