5 - 40 mins Loss of Consciousness to DEATH

FALL SUSPENSION TRAUMA

FALL ! - Arrested by harness

Blood pools in leg muscles. Brain starts to loose oxygen

Brain raises pulse rate and respiration’s to compensate

Gravity makes more blood pool in legs. Reduction in blood flow to brain

Syncopal response triggered. Pulse and breathing rates drop

Slow loss of consciousness. Remains upright

0xygen levels continue to fall. Posture puts Airway at risk

Brain damage

Also known as Orthostatic Shock.

It is the medical term for the body’s inability to cope

with prolonged periods of immobility in a vertical

position.
