  • Page 17: System Introduction

    System introduction 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).

  • Page 18: Cpu Unit

    CARESCAPE Monitor B850 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.

  • Page 19: Input Devices

    System introduction 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.

    CARESCAPE Monitor B850 • GE recommends using the new fasteners (screws, washers, etc.) in the FRU kits rather than reusing the old fasteners. Some fasteners are not intended to be re-used more than three times. • Use only new screws when attaching parts into light metal parts. Before fastening a screw, turn it counterclockwise until it drops into an existing thread pattern.
