Unless all of the soil is replaced at once, the victim is unlikely to break any bones as the grave is refilled. What will happen is that the weight of the dirt will slowly constrict the chest, making it harder to breathe.
As things start to go fuzzy — oxygen is in short supply — the mouth and nostrils will fill with soil, making breathing the air available between particulates impossible. Because hypothermia is a serious issue, few avalanche victims survive past 25 minutes.
Avalanche beacons and teamwork really are the only way out. Brain activity soon follows. Yasmin Tayag. In a coma, you still have brain function, which doctors can measure by observing electrical activity and your reactions to external stimuli. In other words, your body continues to breathe, your heart beats, etc. Even better, you can, potentially, recover from a coma and regain consciousness.
We now have a whole battery of scientific tests to confirm that someone is really, truly brain-dead. Okay, but what if I fall into a deep, deep coma? Will someone eventually pull the plug and send me off to the mortuary?
Will I be trapped in both a casket and in the prison of my mind? We now have a whole battery of scientific tests to confirm that someone is not just in a coma, but really, truly brain-dead.
When a bright light is shined into them, do they contract? Your breathing tube might be moved in and out of your throat, to see if you gag. If you are removed from a ventilator, CO2 builds up in your system, essentially suffocating you. When blood CO2 levels reach 55 mm Hg, a living brain will usually tell the body to spontaneously breathe.
Dead brains have zero electrical activity. A radioactive isotope is injected into your bloodstream. After a period of time, a radioactive counter is held over your head to see if blood is flowing to your brain. If there is blood flow to the brain, the brain cannot be called dead. A person has to fail a lot of tests to be declared brain-dead. And more than one doctor has to confirm brain-death.
As the carbon dioxide builds up it would make you sleepy and you'd eventually fall into a coma before your heart stopped and the rest of your body followed. For you.
