Morphology

life + support

The meaning is directly compositional: 'support' that is for 'life' = assistance essential for survival, so a learner who knows both words can infer the medical or figurative sense. This construction is transparent and parallels expressions in many languages, making it readily understandable to a B1 learner.

Etymology

Life support also comes from the same image of life plus support in dangerous places. It describes systems that give air, water, or heat in submarines or spacecraft so people can 'survive'.
