- Orthostatic Hypotension: In suspension trauma, this refers to the pooling of blood in the leg veins of a worker that occurs when individuals fall in harnesses, are suspended in confined spaces, etc. and are forced to hang vertically with their legs relaxed (immobilized).
- Reflow Syndrome: The return of pooled, hypoxic blood and its metabolic byproducts from the extremities to the heart (more about this later).
- Rescue Death: When related to suspension trauma, this type of death occurs in patients who appear physiologically stable during the rescue and extrication but suddenly die after being freed.
- Suspension Trauma: Injuries Sustained from being immobilized in a vertical position when the legs are relaxed and immoble. Injuries include hypoxia (insufficient oxygen reaching the tissues); syncope (loss of muscle strength and/or fainting); hypoxemia (abnormally low levels of oxygen in the blood causing shortness of breath); acidosis (excessive acid in the body fluids or tissues, build up to CO2); ventricular fibrillation (irregular contractions of the heart where the chambers quiver uselessly instead of pumping blood, generally followed by sudden cardiac arrest); myocardial infarction (heart attack or literally “death of heart muscle”); damage to the liver, kidneys and brain; and possibly death.
- Suspension Syndrome: The condition in which a suspended person becomes unconscious due to orthostasis (upright hanging position) without traumatic injury.
Scarey stuff right? Still with me? The "good" news is that suspension trauma can only affect someone who is immobile – specifically not using their leg muslces to any great extent. It does not normally affect people who wear a harness who are:
- Actively moving about (climbing, rope access, rescue work, etc.)
- Suspended for only a minute or two (parachutists)
