Morphology

pulse + oximeter

The meaning is directly compositional: an 'oximeter' is a device that measures oxygen levels and the modifier 'pulse' specifies the measurement method (via the pulse/fingertip). If a learner knows both constituents, they can infer it is a small device used to measure blood oxygen; similar compounds exist in many languages, so the logic is cross-linguistically transparent.

Etymology

Pulse oximeter comes from what the small device does: it clips to your fingertip and uses light to read your pulse, meaning your heartbeat, and how much oxygen is in your blood, while oximeter is the word for a tool that measures oxygen. So, the name means a small device that measures the oxygen in your blood without cutting the skin.
