How do you fix low oxygen in an aquarium?
You need to aerate it. If you have no filtration/aeration system, get a cup, scoop up water and drop it back into the aquarium from a height of about twenty centimetres. Do this for one minute every four or five hours until you can set up a filtration or aeration system. Overstocked tanks (too many fish) will use up oxygen faster than it can be replaced, even by an aeration system. Adding live plants will also help to remove carbon dioxide and add oxygen to the water.

What happens if air is accidentally injected in to vein while having a blood test?
Well, from what you are saying, my gues is that you or a qualified phlebotomist has attempted to take a minor blood extraction. In which case, if this has happend, your vein/ body will temporarily gain oxygen within your blood supply, which in turn, may leave you feeling slightly more energetic.. just for those few minutes..
note, its not dangerous unless the shringe your using is pressured with too much force which may cause bubbling at the vein tissue or even worse may cause the vein to burst. However, this is highly unlikely and therefore shouldn't come to any harm or cause any sort of pain or discomfort. If you start to notice any pain or unsightly swelling, please don't hessitate to seek medical advice right away. Hope this helped!
