Some patients who have difficulty breathing need to breathe artificial oxygen whilst fasting. Does this have any effect on the fast?.
Praise be to Allaah.
The oxygen that is given to some patients does not invalidate
the fast, because nothing else is added to this oxygen, so it comes under
the same ruling as breathing natural air.
Hence in a statement of the Islamic Fiqh Council it says:
The following things are not regarded as things that break
the fast: … oxygen. End quote.
