How many bedroom plants would it take to replace the amount of oxygen consumed by an average human at night?

Are there any studies on this, with actual numbers. I'm interested in determining how many Mother-in-laws tongue or aloe vera (bedroom plants) i need per person in a bedroom to replace the oxygen

1. Actually, funny thing is that at night plants actually use oxygen too. Only during the day do they use carbon dioxide, at night they respire as well. They do not use as much as you do, but still are competing for oxygen at night as well.
