Actually it takes more than 0. There is in fact a very delicate balance of oxygen concentration within only a few percent. Belowike 14 percent you can suffocate and above like 25 percent the air can become flammable.
21% is what is in normal atmosphere. 14% is safe because that is the threshold that we use to design inert gas fire suppression systems for enclosed spaces (anywhere from a closet to an entire floor of a building for a data center). Fire cannot survive below 14% but we can. A minuscule amount of CO2 is added to the blend to cause involuntary respiration so that while you are getting less oxygen per breath you are taking more breaths per minute to help offset. Long term exposure isn't recommended though.
Or zero water, zero food, zero blood pressure……
100% oxygen will kill you too
How many potatoes does it take to kill an Irishman... Zero.
You just made an enemy 🤬🤬🇮🇪
I've heard that somewhere...
breathing 100% pure oxygen for too long can kill you too.
Actually it takes less than 10% oxygen in the air to kill you.
I haven't ever worded it this way in my head
You can live on a ventilator
You might not.
Still oxygen bro
How about head crushing under a truck tire?
