2 Theory of Operation 2.1 Introduction This patient monitor is designed to monitor a fixed set of physiological parameters including ECG, heart rate (HR), respiration (Resp), temperature (Temp), SpO2, pulse rate (PR), non-invasive blood pressure (NIBP), invasive blood pressure (IBP), cardiac output (C.O.), carbon dioxide (CO2), oxygen (O2), anesthetic gas (AG), impedance cardiograph (ICG), bispectral index (BIS) and respiration mechanics (RM) of single adult, pediatric and neonatal patients.
The patient monitor also:
Provides audible and visual alarm indications in case of patient or equipment problems.
Enables displaying, reviewing, storing and transferring of real-time data.
Incorporates multiple input devices such as buttons, knob, touchscreen, keyboard and mouse.
Interfaces a clinical information system or central monitoring system.
Enables program upgrade over the network.
2-1
2.2 System Connections 2.2.1 Mounting the Patient Monitor The patient monitor can be mounted on a wall bracket or on a trolley support. The wall bracket or trolley support can be ordered optionally. Each type of mounting bracket is delivered with a complete set of mounting hardware and instructions. Refer to the documentation delivered with the mounting hardware for instructions on assembling mounts.
CAUTION z
Use mounting brackets we supply or approve. If other compatible mounting bracket is used, be sure it can be safely used on the patient monitor.
z
The mounting bracket should be installed by our qualified service personnel, or engineers who have adequate knowledge on it.
z
If other mounting solution is used, the installation personnel and the customer should verify if it can be safely used on the patient monitor, and the customer assume the responsibility for any risk resulting from that.

2.3.1 Input System Button board The button board, located at the lower part of the monitor’s front panel, contains 6 keys and provides connections for the following components to the main board:
Knob
Power switch & LED board
Touchscreen control board
Backlight board
Alarm LED board
The following diagram shows the button board connections.
Knob The knob can be pressed, or rotated both clockwise and counter-clockwise. It is connected with the button board.
