I am still new to the game. I usually attack their Shields first and then their Engine. So what you are saying is that I can get more resources if I kill them by knocking out their Oxygen? Should I still knock out their Shields first or should I go straight to the Oxygen? Also, about how long does it take for an enemy crew to die from no Oxygen?
My strategy is to always attack the weapons systems if they have level 1 shields(sometimes level 2-3, depends on my weapons). The first shot will take out the shield then damage the weapons. A Burst Laser Mk2 can go through two shields and hit where you aimed it at, barring misses and evasions.
I hit shields first if I can't break through the shielding in one attack. Once the enemy's weapons are down I'm free to not worry about taking damage until it gets repaired. I then go for engines so the enemy can't escape, then target oxygen. I'm pretty sure the enemy prioritizes repairing life support over all the other systems.
If the crew dies by asphyxiation, fire, or your boarding crew and the ship doesn't blow up, you get more resources. Some species take longer to die from lack of oxygen. Mantis have their HP deplete the fastest, Rock have more HP so it takes longer, and Crystal dudes have a resistance to vacuum exposure. Zoltan have only 70 HP, so they can die faster. Humans and slugs are base models at 100 HP and standard rate of HP decrease. I *think* slugs take at least 45-60 seconds to die.

I usually target engines over pilot, especially if I have a beam weapon so I can hit multiple rooms(engines are almost always next to weapons on rebel ships). A good rule is to attack whatever the smaller of the two rooms is, because it will have the fewest number of people repairing it. If the cockpit only has room for 2 and the engines room for 4, engines can get repaired faster. But if you have bombs, one strategy is to damage/destroy systems in a 4 man room, then spam bombs there to take out the crew repairing it.
