Inert gas hypoxia is painless if done right. This is Alabama though, so I wouldn’t trust them to even use the right kind of gas, much less administer it correctly.
My understanding is that the problem with the gas mask is not oxygen, but rather it’s so small that CO2 builds up, so the prisoner feels that they are suffocating.
A problem that has been solved for respirators meant for breathing, including in space when you don’t want to just expel the air to the surrounding environment. If it’s ok to expel it to the environment, the technology is as simple as a rubber flap over a hole in the mask.
Though reading more about it, there are mechanisms that could still cause distress even if the mask is designed to expel CO2 properly, including CO2 poisoning because the body’s ability to expel it can be compromised by the lack of oxygen. And it’s possible that executionees experience inert gas asphyxiation differently from accidental victims because they are aware of what’s happening while accidental victims might pass out without ever realizing they were dying, which can affect the way the body uses resources.

They don’t. They put a gas mask on the prisoner, which lets oxygen in, rather than putting them in an airtight chamber.
