'oxygen-promoting' originates from Modern English, built from 'oxygen' (from French 'oxygène' and Greek 'oxys' meaning 'sharp/acid' + '-gen' meaning 'producer') and 'promoting' derived from Latin 'promovere', where 'pro-' meant 'forward' and 'movere' meant 'to move'.

'oxygen' was coined in the late 18th century (French 'oxygène', from Greek elements 'oxys' + '-genēs'); 'promote' comes from Latin 'promovere' via Old French 'promouvoir' and Middle English 'promoten', with the present participle 'promoting' used in Modern English to form compounds such as 'oxygen-promoting'.

Initially the component 'oxygen' referenced the idea of 'acid-producer' (per its coining), and 'promote' meant 'to move forward or advance'; in Modern English the compound 'oxygen-promoting' now specifically denotes something that increases oxygen availability or uptake.
