Modules designed to be used as a component of a physiologic monitor, along with related devices, to acquire, measure, and process information for the purposes of intermittently measuring and/or continuously monitoring invasive pressures (e.g., arterial blood pressure, intracranial pressure, central venous pressure, pulmonary artery pressure). These modules contain electronic circuits or other technology designed to acquire and/or process the signal from one or more physiologic sensors (e.g., electrodes, catheter/pressure transducer sets) and transmit it to the physiologic monitor, which contains the software designed to support the module\'s intended function(s). Invasive pressure 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., a module rack) in order to support the desired function(s). Typical functions of an invasive pressure module, when used with a physiologic monitor, include continuous monitoring of arterial blood (systolic, diastolic, and mean) pressure, central venous pressure, pulmonary artery (systolic, diastolic, and mean) and capillary wedge pressures, and intracranial and cerebral perfusion pressures. Various waveform and alphanumeric displays, along with visual/audible alarms, are typically supported. Some modules may provide additional hemodynamic monitoring functions or can be used to monitor other invasive pressures, such as intra-abdominal pressure, when used with the appropropriate sensors and accessory devices.
