In a patient controlled analgesia (PCA) system, physiological data is pro cessed and alarms are provided by the controller of the physiological module sensing the data according to a first rule. The physiological data is also processed by a second, separate controller according to a second rule indepe ndent from the first controller. According to the second rule, the physiolog ical data may be filtered, processed with physiological data and non-physiol ogical data obtained from another source, such as a remote server, and the P CA delivery device controlled to prevent delivery of medication accordingly. The provided system of multiple processors and rules enables normal alarmin g by physiological sensor modules while the pausing or prevention of the PCA delivery is controlled by a separate controller. Through this means, not on ly are false pauses and alarms for PCA delivery reduced, but the normal alar ms of the monitors are permitted to function normally. |
