Anoxia will hit the crew when the atmospheric pressure drops to what pressure?
From Living In Space by G. Artwork by Rick Sternbach. Low pressure is attractive; since it uses less mass and the atmosphere will escape more slowly through a meteor hole.
Unfortunately the required higher oxygen level make living in such an environment as hazardous as chain-smoking inside a napalm factory. NASA found that out the hard way in the Apollo 1 tragedy. Since then NASA always uses high pressure, they use low pressure in space suits only because they cannot avoid it.
This does raise a new problem. There is a chance that the high-oxygen atmosphere will allow a meteor to ignite a fire inside the suit. There are other problems as well, the impossibility of air-cooling electronic components and the risk of long-term health problems being two.
Setting up the optimal breathable atmosphere is complicated. A more annoying than serious problem with low pressure atmospheres is the fact that they preclude hot beverages and soups.
It is impossible to heat water to a temperature higher than the local boiling point. And the lower the pressure, the lower the boiling point.
You may have seen references to this in the directions on certain packaged foods, the "high altitude" directions. The temperature can be increased if one uses a pressure cooker, but safety inspectors might ask if it is worth having a potentially explosive device onboard a spacecraft just so you can have hot coffee.

It occurs when a person has been breathing an atmosphere containing inert gases generally nitrogen or helium and they move into an environment with lower pressure. This is commonly when they put on a soft space suit or the room suffers an explosive decompression. It has all sorts of nasty effects, ranging from joint pain and rashes to paralysis and death.
The large joints can suffer deep pain from mild to excruciating. The brain can have sudden mood or behavior changes, confusion, memory loss, hallucinations, seizures, and unconsciousness. The legs can become paralyzed.
