A method and system for patient monitoring wherein data acquired by parameter measuring modules is downloaded to an information processing and display station. Table data structures resident within the modules are downloaded to the display station during initialization of the module on the link. The tables completely define the number, functionality and visual attributes of all control keys associated with each channel of the module. The tables include: text and parse tables which define the number, size, attributes and text for each key; a process table which contains a plurality of control programs which are executed by an interpreter portion of the display software in response to activations of a control key; and a channel control table which modifies the operating conditions of the channel in response to preselected control keys. A module header table is provided which defines display memory requirements of the tables for the module's channels, and an active-module table provided by the display station maintains a list of modules active on the link and the location of the module header tables once they are downloaded.

Table driven multichannel data acquisition and display for signal

An electronic system is disclosed which examines the first derivative of an applied electrocardiographic (ECG) signal, recognizes the R-wave event therefrom, and discriminates against signal components which lie outside predetermined signal parameters in producing a rectangular pulse output. In addition, muscle artifact and pacers are discriminated against. The system includes an automatic gain control to eliminate the need for operator controls.
