Morphology
The term is compositionally predictable: 'digital' in the medical sense means relating to a finger or toe and 'plethysmograph' is an instrument that measures volume changes, so a learner can infer it is an instrument for measuring volume/blood flow in a finger or toe. It is technical vocabulary and 'digital' can be ambiguous (often means 'electronic' in everyday use), but given the provided constituent meanings the overall sense is transparent.
Etymology
The name digital plethysmograph comes from two parts: digital means 'finger' or 'toe' and plethysmograph is a machine that records small changes inside the body. So the name paints a clear image, a small clip on a finger that watches the blood, which is why it means 'a device that measures blood flow in the skin'.
