3 System introduction
3.1 Short description of the equipment
The CARESCAPE Monitor B850 is a modular multi-parameter patient monitor that is meant for
high-acuity applications.
The monitor can be used with most patient populations within a professional healthcare
facility, but acquisition modules may have limitations for use based on the patient’s age,
weight, or clinical condition, or on the type of the care unit (for example, OR or ICU only). There
are several types of acquisition modules to choose from based on care requirements and
patient needs.
The modular system design is inherent in electronics and algorithms: some processing of the
measurement signals is done by the acquisition modules and further processing happens on
the monitor.
Measurement values are displayed as graphic or numeric values, like waveforms and numbers,
and when applicable, also as alarm messages.
The monitor supports three independent displays, and the screen contents shown on each is
user-configurable. The D19KT VER01 display has an integrated alarm light.
The user interface can be used as a touchscreen, or with a Trim Knob or a mouse and a
keyboard. The most important and commonly used functions have main keys either on the
main menu (soft keys) or on the monitor front panel (hard keys). The menu structure design
allows access to all functions needed by the clinical user with just a few clicks.
The monitor transfers the measurement data to central stations and to the hospital patient
data depositories. It communicates with a variety of other bedside medical devices and
monitoring systems.
For all physical and performance specifications, refer to the supplemental information
provided.
3.2 System components
The patient monitoring system is typically composed of these main parts:
•CPUunit
•Software
• Display
•Inputdevices
• Module frames
• Acquisition modules: Patient Data Module (PDM), Patient Side Module (E-PSMP) and other
E-modules
•Network
• Printers and writers
• Accessories and supplies (for example, ECG leadwires/cable sets, mounts)
The CARESCAPE Monitor B850 monitoring system components are introduced below.

2106778-001
3.2.1 CPU unit
The primary function of the patient monitor is to render a clinically meaningful display of
acquired patient data and allow the caregiver control (alarms, configuration, etc.) of the system
through the user interface. The CPU unit is the central processing unit for the patient
monitoring system and provides a link between parameter acquisition and input/output
devices. It also facilitates network communication and interface to several ancillary devices (for
example, printers, displays). The patient monitor works with multi parameter acquisition
devices.
In addition to the primary function to display patient data, the patient monitor software has a
service interface for performing device level service tasks such as configuration, maintenance
and troubleshooting. Refer to the the patient monitor’s supplemental information manual for
care area specific software and features.
3.2.2 Software
The patient monitor is highly configurable and provides many monitoring possibilities with a
flexible software licensing model.
The monitor supports care area specific software packages for OR, PACU, ICU, ED and NICU.
Each dedicated software package provides a comprehensive feature set for the different
monitoring needs and can be further extended with the optional feature licenses.
Software license model supports trial licensing and easy field upgrades with license key
activation.

3.2.3 Input devices
You can connect several USB input devices to the patient monitor, including alphanumeric
keyboard, mouse, remote control and barcode reader.
Refer to the patient monitor’s supplemental information manual for a list of compatible USB
input devices.
Keyboard
A washable, antibacterial keyboard is specified for
use with the monitor. It may be connected to the
monitor or display via one of the USB connectors.
The keyboard allows you to enter data without
using the touchscreen display.
Mouse
A standard mouse may be connected to the
monitor or display via one of the USB connectors.
The mouse allows you to select any on-screen
items without a Trim Knob control or a touchscreen
display.
Remote control
The remote control provides 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.

Technician ID and Patient Information from
barcodes when admitting patients.
