The outer airlock hatch is left open for two minutes and twenty seconds, minimum, after the antagonist explosively opens the inner airlock hatch. The air rushes past the individuals in the lock at a high rate of speed, rapidly depressurizing the ship (as evidence by ship warnings declaring emergency oxygen is being released into the ship). This goes on and on, while the heroes spend a lot of time struggling with Zac. In reality, the wind would die down quickly, and a good portion of the ship would be in a severely depressurized atmosphere in a very short time, causing almost immediate loss of consciousness for anyone not holding their breath (which Zac clearly was not doing, as he can be heard grunting and gasping for breath while struggling).
