Since the word “placebo” means “fake” in the terminology of pharmacological and clinical research, “placebo oxygen” means “fake oxygen”, in the same way as “placebo pill” means “fake pill”, namely, with no pharmacological ingredients inside. To be more specific, breathing fake oxygen means breathing through a mask from an empty tank, that is, with no oxygen inside at all.
