With the oxygen levels dropping Rumun knows that he has to be quick. He has two respirators in case the ship's oxygen runs out, one currently in his possesion and the other one inside his survival kit at the entrance of the ship. Calmness and pacience is the key to survival. Desesperation and physical activity will make the oxygen run out even more quickly.
Besides, there must be even more respirators masks around the ship. Every ship has emergency breathers.
In any case, he goes to the bridge's comunication console and tries to reach the the Nova Devils.
