The answer is avoid giving oxygen under positive pressure.
A blast injury is a complex type of physical trauma resulting from direct or indirect exposure to an explosion. Blast injuries occur with the detonation of high-order explosives as well as the deflagration of low order explosives. These injuries are compounded when the explosion occurs in a confined space.
I'm not too sure how to save the victim's life in a situation like this, but you SHOULD NOT give oxygen to a victim who has suffered from an explosion at close-range, while under positive pressure.
The depth is remaining constant in the surface layer, so that indicates the surface layer is. well mixed. C. The salinity is fairly constant in the surface layer, so that would indicate the layer is well. mixed
