7 Bleeding, Wound Care and Trauma

Blast injury Blast injury, though thankfully rare, can occur both in the workplace and the home. Many industries use explosives in their daily operations, but blast injury can come from any type of explosion including natural gas or other fuels. Mechanism of Blast Injury Primary blast – The direct effect of the pressure wave on the body. Damage is concentrated on structures and organs containing air such as the lungs, stomach, intestines, and inner ear. Secondary blast – Being struck by objects propelled by the blast force such as metal, glass, or masonry. Tertiary injury – Being thrown bodily by the explosion and striking objects such as trees, cars, buildings, or the ground.

First Aider in Action: Part 6 The wound has almost completely stopped bleeding as you apply the third dressing. Anita has painted toenails, so you check for perfusion by gently squeezing her toe. Colour returns quickly so you know her perfusion is good. As you begin to apply a bandage, you ask the person who securedd the broken glass to put on gloves and carefully clean up the glass and the wrappers from the dressings and bandage. One of your friends has volunteered to drive so you send her ahead to get the car ready and bring it as close as possible. How will you move Anita to the car?
