Abstract
Medical devices can perform a plurality of functions, such as sensing, monitoring, deriving and/or calculating various physiological statuses of a patient (e.g., blood pressure, temperature, respiration rate, etc.). Medical devices can also be used to image part or all of a patient's body, to deliver a treatment, or to manage information related to a patient's care. The present disclosure is directed at one or more devices that perform these functions using a plurality of processing circuits, wherein each processing circuit has a timing circuit with a local clock. These processing circuits can be connected via a network, and each timing circuit can communicate with at least one other timing circuit in order to detect and correct time-differences between their local clocks. In this way, multiple processing circuits can be synchronized with each other to facilitate diagnosis or treatment of a patient's condition, or other aspects of a patient's care.
