Morphology
plethysmography = plethysm + graphy
Although '-graphy' suggests a recording or measurement method, 'plethysm' is a highly specialized scientific element, so the full meaning is not readily inferable for an average learner.
Etymology
Plethysmography comes from the parts plethysmo- meaning 'full' or 'swelling' (think of plethora, 'a lot') and -graphy meaning 'writing' or 'recording'. So, plethysmography is like 'writing down' how full or swollen a body part is, which is why the test measures changes in blood flow or the air in the lungs.
