Pneumonic pulse pattern was the pattern of inhalation and exhalation of the lungs. Each pattern was unique to an individual.

In the mid-2270s, V'ger copied this pattern accurately when creating the Ilia probe. This pattern was one of the aspects of the probe examined by Doctor Christine Chapel. Data from this examination was displayed on a viewscreen in an examining room aboard the USS Enterprise. (Star Trek: The Motion Picture)
