Wouldn’t Nitrogen asphyxiation be similar to drinking oneself to death?
How about the 10000 ft drop out of an airplane. The ride down is probably fun and it is only the sudden stop that kills.
Yeah, when divers get too much nitrogen in the mix, they get intoxicated and it is supposed to be very similar to the effects of alcohol.
Nitrogen asphyxiation is the same as passing out. You lose peripheral vision, your reaction time slows, just like alcohol poisoning. However, with a sudden flood of nitrogen, you would pass out completely in about 20 seconds.
It would be very easy to learn from emergency responders and workers who have been rescued from oxygen deficient atmospheres whether there is any pain or suffering. From everything I’ve read, there isn’t.
