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), SpO
2
, pulse rate (PR),
non-invasive blood pressure (NIBP), invasive blood pressure (IBP), cardiac output (C.O.),
carbon dioxide (CO
2
), oxygen (O
2
), anesthetic gas (AG), impedance cardiograph (ICG),
bispectral index (BIS), respiration mechanics (RM), continuous cardiac output (PiCCO),
central venous oxygen saturation (ScvO
2
), electroencephalograph (EEG), and neuromuscular
transmission (NMT).
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.
Integrates the information of other devices, which include but are not restricted to
anesthesia machine and ventilator.
