Can someone please explain why "explosive decompression" would kill you instantly?

I can understand explosive compression, but still don't understand how this worked:

It causes gases within the blood to boil, such as nitrogen. This can cause gas embolisms, these can cause blockages within your circulatory system.
Then, there is also things like barotrauma, which can rupture your lungs.
There is also the risk of physically being crushed by the greater external pressure, like a cola can.

According to the medical findings, rapid formation of tiny bubbles in the blood caused lipoprotein complexes to denature rendering the fat they contained to be insoluble, causing blockages which stopped circulation completely

that's not explosive decompression

It doesn't. All those people were murdered by CIA niggers trying to suppress the history of the ARYAN EVROPEAN VOLK because they discovered during their dives evidence of Thulean civilization.

You mean other than your entire body being forced through a hole the size of a golf ball?

Supposing you aren't ripped to shreds by the more obvious physical forces the reason is basically a super version of the bends.

>forensic pathologists determined that Hellevik, being exposed to the highest pressure gradient and in the process of moving to secure the inner door, was forced through the 60 centimetres (24 in) diameter opening created by the jammed interior trunk door by escaping air and violently dismembered, including bisection of his thoracoabdominal cavity, which resulted in expulsion of all of the internal organs of his chest and abdomen, except the trachea and a section of small intestine, and of the thoracic spine.

It is only instant when there is Delta-P and you get sucked through a small opening. Otherwise, your blood will start to "boil" and that will kill you in a number of ways.

Holy fuck that was brutal. And caused by a mere 8 atmospheres of ΔP? Damn it.
Also:

>caution: opening this clamp will kill you and everyone else in the room
Sounds like a MASSIVE fucking design mistake.
Even if they had to use a hatch that opens outwards, it should be locked with a key and opened with a very specific procedure.

Explosive decompression is when air vacates a space at supersonic speed, and it's effects are in some ways even more severe than the trauma caused by explosive shockwaves. Decompression at supersonic speeds destroys the lung tissue and causes other pressurized organ systems like the circulatory system to rupture, resulting in essentially guaranteed death.
>>10434780
It was, and to some extent has been rectified in more modern oil drilling pressure chambers.
>>10432240
All the hundreds of pounds of super pressurized atmosphere are trying to get out through the hole, you're in the way, your body is slammed into and then through the hole by several hundred pounds of atmosphere traveling at near or past supersonic speeds.

Nothing can kill you instantly, lots of things can kill you very fast though.
It's the same as CO2 dissolved in soft drinks, under pressure it stays dissolved but when pressure is reduced it outgasses, rate depending on by how much the pressure is reduced.
When humans are under high pressure like in diving they get a lot of extra atmospheric gasses dissolved in their blood/tissue, including things like nitrogen and neon depending on their breathing mix.
All the extra dissolved gas will go back out as pressure is reduced to 1atm, and will have the volume of that amount of gas at that pressure.
If you depressurise slowly the gas will go out the normal way by exchange in your lungs, it'll take up about normal volumes relative to your lungs and you'll live.
If you depressurise fast/explosively the gas all comes out at once while still in your blood/tissue, and takes up its 1atm volume (or as much as it can against the elasticity of your body) which can result in being blown apart or getting the bends.
