Reply to comment by Killer-Barbie in TIL This palliative care paper determined that a stream of air from a bedside fan relieves dying patients of dyspnoea (breathlessness/ shortness of breath) as equally as supplemental O2. by No_Cauliflower_5489

Perhaps, but it could also simply be that without a fresh breeze, the oxygen in the room might be depleted enough from rebreathing to matter. Or perhaps more likely, the raised C2O causes problems with blood ph.

You have to be sucking air down at a truly prodigious rate to noticeably deplete the oxygen levels of a modern mechanically ventilated room

No. The science on it says no. Just no. All of it. No.

You’re being downvoted but you may not be wrong. The paper in OP’s link seems to be essentially talking about a placebo effect that makes patients feel better.

Furthermore. CO2 buildup in indoor spaces (or more generally poor indoor air quality) has been identified as a problem in many building and in fact building codes are changing to require measurement and corrective actions (if required).

All of this contributes to how patients do and feel.
