Manual information
Revision history
Each page of the document has the document part number and revision at the bottom
of the page. The revision changes whenever the document is updated.
Intended use
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.
