Not tightening enough
600

600
What scale do we use to measure a casualty's level of consciousness? And what does it stand for?
AVPU! Alert, verbal, pain, unresponsive
600
List two actions to prevent field hypothermia.
Remove wet clothing, wrap casualty in insulating materials, keep off ground.

What is a tension pneumothorax?
A tension pneumothorax is when air gets trapped inside the chest and it can’t get out. This builds pressure inside the chest cavity, which pushes onto other organs.
