No we cant. It has to be first converted into gas cz 1. its too cold, 2. Our lung dont allow liguid exchange across the Alveoli…. However it could be transported in the liquid state under pressure …..
We can make oxygen a liquid, either by making it really cold (-183 degrees centigrade), or under really high pressure (or both). Either of these things are really bad for our lungs. I wouldn’t advise it.
