Chapter 1 About the Product
1.1 Introduction
The
PM-7000 Patient Monitor (
hereinafter called PM-7000 for short), a portable and
accessible patient monitor, is supplied by rechargeable batteries or external AC/DC power,
which applies to adults, pediatric and neonates. You can select different configurations as
required. Besides, the PM-7000 can be connected with the central monitoring system whereby
a monitoring network will be formed. Parameters that the PM-7000 can monitor include: ECG,
RESP, SpO
2
, NIBP, 2-channel TEMP, 2-channel IBP, CO, CO
2
and AG. 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 7 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-7000 measures patient’s ECG, NIBP, SpO
2
, 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.
1.2.2 Usage
Parameters that the PM-7000 include: ECG, RESP, SpO

.
PM-7000 converts these physiological signals to digital signals, processes them and displays
them on the screen. You can set the alarm limit as required. When the monitored parameter
