Chapter 1 About the Product
1.1 Introduction
The PM-9000 Express Patient Monitor, a portable and accessible patient monitor, is supplied
by rechargeable batteries or external AC power, which applies to adults, pediatric and
neonates. You can select different configurations as required. Besides, the PM-9000 Express
can be connected with the central monitoring system whereby a monitoring network will be
formed. Parameters that the PM-9000 Express can monitor include: ECG, RESP, SpO
2
, NIBP,
2-channel TEMP, 2-channel IBP, CO and CO
2
. It, integrating the functions of parameter
measurement, waveform monitoring, freezing and recording, is a compact and lightweight
patient monitor. Its color TFT LCD is able to show patient parameters and 8 waveforms clearly.
The compact control panel and knob control, and the easy-to-use menu system enable you to
freeze, record, or perform other operations conveniently.
The PM-9000 Express Patient Monitor measures patient’s ECG, NIBP, SpO

, TEMP, RESP,
IBP, CO and CO

physiological signals through the ECG electrode, SpO

sensor, cuff,
temperature sensor and pressure transducer. During the measurement, the patient monitor
does not get energy or any substance from the human body, and does not release any
substance to the human body. However, it releases sine wave signals to the patient when
measuring the respiration rate. The patient monitor converts the measured physiological
signals to the digital signals, waveforms and values, and then displays them on the screen.
You can control the patient monitor through the control panel. For example, you can set
different alarm limits for different patients. Thus, when the patient monitor detects any
physiological parameter exceeding the preset alarm limit, it will enable the audio and visual
alarm.
1.2 Application
1.2.1 General
In the treatment processes, it is necessary to monitor important physiological information of
patients. Therefore, the patient monitor has been playing an outstanding role among medical
devices. The development of technology does not only help medical staff get the important
physiological information, but also simplifies the procedures and makes it more effective. For
patients in hospital, the basic and important physiological information is required, including
ECG, SpO
2
, RESP, IBP, CO, CO
2
, TEMP, etc. In recent years, the development of science and
technology helping measure and get important physiological information of patients has made
the patient monitor more comprehensive in performance and better in quality. Today,
multi-parameter patient monitors are widely used.
