Don't google injection injuries. Make a small hole in that when it's under pressure and it's you who becomes fuel injected.

Mithaldu posted:Ever watered a lawn with a simple hose? Put your thumb over the hole? Same effect, only with a microscopic hole and LOOOTS more pressure. Welp, just a slight nick on the finger.. Figure 4A. Case 4  Case 4 A 25-year-old male plant manager sustained a high-pressure injection injury while disassembling and air gun he did not know was still pressurized. While removing the nozzle, an unknown substance was injected into his non-dominant left index finger. He thought the substance was either paint thinner or dirty water. At presentation, the patient complained of pain and numbness of the injected digit and palm. There was a small laceration on the volar surface of the digit in the crease of the proximal interphalangeal joint ( Figure 4a ). He was taken to the operating room and the index finger and palm were opened with a modified Brunner incision ( Figure 4b ). Extensive debridement of devitalized tissue was performed. The odor of paint thinner was noted and there was evidence of chemical necrosis of the adipose tissue in a large segment of the hand. In the first surgery, thorough irrigation was performed and the wound was left open. We believe this patient had a systemic reaction to the injected paint thinner. After the initial surgery, he became hemodynamically unstable and required admission to the intensive care unit and treatment with pressors. He stabilized by the next morning. Signs and symptoms of compartment syndrome occurred on post injury day 2 and required a return to the operating room. Fasciotomies of the dorsum of the hand and anterior compartment of the forearm were performed ( Figure 4c ). Several trips to the operating room were required for repeated debridement of devitalized tissue including amputation of the left index finger.  http://www.orthopaedicsone.com/display/Cases/Four+Cases+of+High-Pressure+Injection+Injury+of+the+HandMostly text, only the bottom has some smallish photos of injuries unless you click on them.

What would happen if you withdrew from another man when inside the hyperbaric chamber? I can't imagine physical specimens like deep sea divers are able to control themselves for the length of time they are all required to be in there together, so I presume we have an answer to this.

Plenty has been written on this topic, this is just the first decent article I found with a quick search. http://www.iflscience.com/space/what-would-happen-your-body-space-without-spacesuit/ Note that the pressure difference between 9 and 1 atm is much more than between 1 and 0, so the effects of explosive decompression from diving pressures tend to be much worse than those from atmospheric pressure to a vacuum.

The Lone Badger posted:You are not compressible. You are extremely deformable. When I was in the Army, I worked on the Apache AH-64A attack helicopter. My specialty was wiring, but I also was in charge of the Ground Power Unit, a jet engine in a box that generated power, air flow, and hydraulic pressure for an Apache on the ground. The pressure was over 1000psi in the system that ran all the hydraulic stuff, including moving the gun around. There were a few times that I swung cloth in front of me to see if there was a hydraulic leak. Never found a high pressure one, though.

Fun fact: This similar to how they remove the skin for leather at animal rendering plants. They stick an air hose just under the skin and blow it up like a balloon. Then it's really easy to peel off.

Goatman Sacks posted:I never really understood hyperbaric chambers - can you really make a human body just tolerate 9 atm of pressure as long as you ramp it up slowly? The record for a simulated dive is 71 atm. Main problem is finding a gas you can breath at those pressures. They used hydrogen and helium with a tiny bit of oxygen so it's not explosive. Even a tiny bit gives more than enough partial pressure when you're that deep. If someone opened the door accidentally, "instant human souffle" would probably be the best description as all the dissolved gases in the body's water content would bubble out at once.
