Physiologic Monitor Modules, Intravascular Oximetry

Definition : Modules designed to be used as a component of a physiologic monitor, along with related devices, to acquire, measure, and process information for the purpose of continuously monitoring mixed venous oxygen saturation levels. Venous oxygen saturation level is a measure of the oxygen delivered minus the oxygen consumed; clinically significant venous oxygen saturation changes can be used as an early indicator of physiologic instability. These modules contain electronic circuits or other technology designed to acquire and/or process a signal from one or more physiologic sensors (e.g., catheter/transducer sets) and transmit it to the physiologic monitor, which contains the software designed to support the module's intended function(s). Intravascular oximetry monitor modules must be inserted in a dedicated location (e.g., "slot") within a physiologic monitor (e.g., modular or modular/configured bedside or transport monitor) or related device (e.g., module rack) in order to support the desired function(s). Typical functions include display of numeric values/trends for venous oxygen saturation level and appropriate initiation of visual/audible alarms. Many modules also monitor venous oxygen saturation level along with the oxygen saturation of hemoglobin in arterial blood and display related data (e.g., plethysmogram waveforms, numeric values).
