At any time, you would have about a dozen seconds worth of oxygen in your bloodstream. Also, your mucles have a little buffered ATP so will temporarily function without immediate oxygen.

Most of your body will function for up to a few, but you should assume brain and eyes will become less useful sooner, as your blood oxygen starts to lower. It becomes harder to think, and harder to coordinate movement.

Most of your body will function ''at all'' for up to a few minutes, but you should assume brain and eyes will become less useful much sooner, as your blood oxygen starts to lower.
It'll help to choose your use of muscles well.

It becomes harder to think, harder to coordinate movement, so overall much harder to get yourself to safety.
