Seven Keys

Trapped by a warlock, you are presented with seven keys that you must use to open and traverse an array of portals to escape, each of which replenishes or consumes air from the rapidly diminishing supply. However, time is strange here and you must succeed before you are forced to relive it all again and again. 

The solution is intended to be discovered through trial, error, and observation, but for those in a hurry, the puzzle details follow:

SPOILER

-Each key opens a certain number of portals.
-Keys are more likely to open red portals than blue portals.
-One key opens all the portals; only this key opens the center portal.
-Key location, key appearance, and portal location are randomized every time a room is entered.
-Upon entering, opened portals with blue glyphs add 25%, 50%, or 75% more air up to the maximum supply.
-The center portal refills the air to the maximum.
-Upon entering, red portals take 25%, 50%, or 75% of the remaining air supply.
-Pass through any seven portals with air remaining and you succeed in leaving the prison.
