The CARESCAPE™ Monitor B850 is a multi-parameter high acuity patient monitor intended for use in multiple areas within a professional healthcare facility.

The CARESCAPE Monitor B850 is intended for use on adult, pediatric, and neonatal patients and on one patient at a time.

The CARESCAPE Monitor B850 system is indicated for monitoring of Hemodynamic (including ECG, ST Segment, Arrhythmia Detection, ECG Diagnostic Analysis and Measurement, Invasive Pressure, Noninvasive Blood Pressure, Pulse Oximetry, Cardiac Output, Temperature, Impedance Respiration and SvO2 (Mixed Venous Oxygen Saturation)), Airway Gases (Fi/Et CO2, O2, N2O and Anesthetic Agent), Spirometry, Gas Exchange (O2 Consumption (VO2), CO2 production (VCO2), energy expenditure (EE), and respiratory quotient (RQ)) and neurophysiological (including electroencephalography (EEG), Entropy, Bispectral Index (BIS) and Neuromuscular Transmission (NMT) Monitoring) status.

The CARESCAPE Monitor B850 provides alarms, trends, snapshots and events, and calculations and can be connected to displays, printers and recording devices. The CARESCAPE Monitor B850 can be a stand-alone monitor or interfaced to other devices. It can also be connected to other monitors for bed to bed viewing and to data management software devices via a network.

The CARESCAPE Monitor B850 is intended for use under the direct supervision of a licensed healthcare practitioner, or by personnel trained in proper use of the equipment in a professional healthcare facility. In addition to the healthcare practitioner, the CARESCAPE Monitor B850 is designed to provide configuration and troubleshooting capabilities to qualified service personnel.

The CARESCAPE Monitor B850 is not intended for use during MRI.

Refer to the “CARESCAPE Monitor B850 Addendum for Device Compatibility” for a list of compatible devices.

Input devices

Input devices include remote control, keypad, keyboard, mouse and barcode reader.

 The remote control and keypad provide all patient monitor controls on a portable

component with a TRIM KNOB control. The remote control is connected to the patient monitor via one of the USB connectors at the back of the processing unit or at the bottom of the display. The keypad is connected to an M-port and can be mounted on the display or on a separate holster that has various mounting configurations.

 A standard keyboard and mouse may be connected to the patient monitor or

display via one of the USB connectors on the back of the processing unit or at the bottom of the display.

 The barcode reader, which may be connected to the patient monitor or display via

one of the USB connectors on the back of the processing unit or at the bottom of the display, can be used to scan patient data from barcodes when admitting patients.

a list of compatible devices.

Module Frames and Tram-Rac housing

F5 and F7 Module Frames provide an interface between the patient monitor and EModules. The F5 Module Frame has 5 module slots that support a series of E-module acquisition devices. It supports both PDM and PSM with a slide mount. The F7 Module Frame has 7 module slots.

The Tram-Rac housing provides an interface between the patient monitor and a TRAM module or a single parameter Tram-Rac module.

Acquisition modules

E-Modules and PDM

Refer to the “CARESCAPE Monitor B850 Addendum for Device Compatibility” for a list of compatible devices and parameters monitored by PDM, each E-module, TRAM module and single parameter Tram-Rac module.

Hemodynamic multi parameter acquisition modules are the Patient Data Module (PDM), Patient Side Modules (PSM), E-PRESTN and TRAM modules. They provide connection to the patient, process patient data signals, and send patient data signals to the patient monitor.

E-modules and the PDM offer a wide variety of parameter acquisition capability to the patient monitoring system. Refer to the “Module Frames and Modules Technical Manual” for detailed information on each E-module and the PDM.
