Abstract

A processing device and display system supporting a plurality of different modules providing different functions used in delivering healthcare to a patient, includes a patient monitoring module, including a processor, for acquiring and processing signals derived from sensors suitable for attachment to a patient. A patient treatment module, including a processor, supports delivering treatment to the patient using a treatment delivery device. A central processor exchanges data with module processors and processes signals derived from said patient treatment module to support monitoring of patient condition while concurrently monitoring operation of said treatment delivery device in delivering said treatment to said patient.
