How-To
A crush injury can result from any object that exerts applied and continual force on the body. Without immediate first aid and medical attention, a crush injury can lead to heart, lung, and kidney failure.
Any object that exerts applied and continual force on the body can result in a crush injury. Car accidents or collisions, fallen trees, at home or industrial accidents are all common incidents that may cause a crush injury.
A crush injury can be life threatening depending on where it is on the crushed victim's body, and how long they have been trapped - that is, the compression time.
When a limb or body part is under pressure, blood flow becomes restricted to that area. In cases of a crush injury, this causes a build up of toxins that have severe internal and external complications and lead to heart, lung and kidney failure.
The severity of a crush injury is dependent on how long the crush is sustained. Applying immediate first aid along with calling 000 for emergency medical attention is paramount.

Crush injury is most common in accidents - car collisions, objects falling in industrial or domestic accidents, or a fallen tree. Crush injury is common during natural disasters such as floods, earthquakes or bushfires, where buildings, furniture, trees or tree limbs become dangerous, unpredictable objects.
A crush injury to the head, neck or chest is life-threatening. Pressure exerted on vital life functioning organs such as the lungs, brain and spinal cord can result in immediate or rapid death.
A crush injury to the rest of the body can also be life-threatening and should always be treated as an emergency. Damage from a crush injury includes:
The longer a person is trapped under crushing forces, the greater their likelihood of developing acute crush syndrome.
Crush syndrome refers to a very serious condition that can interfere with the body's chemistry and result in the affected limb being amputated.
Crush syndrome can occur when prolonged pressure and force is applied to a part of the body. In a crush injury, blood flow is restricted both to and from the area and the cells, suffering from lack of blood flow, start to effectively die. They then release an excessive amount of toxins, such as potassium, phosphorus and myoglobin.
Crush syndrome is a condition that happens when the pressure is released. Blood once again flows into the area and transports the excessive amount of toxins to the rest of the body. These toxins can disrupt the regular functions of the heart, lungs and kidneys. If not treated promptly and correctly it may result in rapid organ failure that leads to death.
The most obvious signs of a crush injury will be the object causing the crush. As crush injuries are usually accidents and unexpected, check, ensure and be aware that the surroundings are safe before administering first aid.
Signs and symptoms may vary depending on the location, pressure and circumstances of the crush injury - some victims experience excruciating pain, while others lose all feeling. External signs of injury can include:
When treating a crush victim, it is important to assess the emergency scene for any physical risks, as the most obvious sign of a crush injury is the object causing the accident, such as a fallen tree or crashed car.
All crush injuries should be assessed by a medical professional. Seek and follow emergency professional advice if administering first aid to a crush injury:
Crush injury is caused by heavy pressure when a body part is jammed between two objects. Crush injuries may result from car accidents, fallen trees, falling objects, or industrial, domestic or agricultural accidents.
Crush injury can be fatal, life-threatening and may result in the amputation of limbs. It is important to treat any crush injury as an emergency and call an ambulance.
If the crush is sustained for a long period of time it can cause crush syndrome, the release of toxins that cause brain, lung or kidney failure.
