Methods, systems, and apparatuses integrating medical device data are disclosed. In an example embodiment, a vital sign monitor apparatus includes a renal failure therapy interface configured to receive a renal failure therapy parameter from a renal failure therapy machine performing a renal therapy treatment on a patient and an infusion pump interface configured to receive an infusion parameter from an infusion pump performing an infusion treatment for the same patient. The apparatus also includes a vital sign monitor engine configured to display, within a combination user interface of a vital sign monitor, the renal failure therapy parameter within a renal failure therapy timeline, and the infusion parameter within an infusion timeline that is aligned with the renal failure therapy timeline.
