P/N 9005-30-08530 Mindray PM7000 PM8000 PM9000 Patient Monitor Spo2
Board
The monitor measures the patient's SpO2 (oxygen saturation) and
displays the following information:
1.Pulse value (PR) in the ECG parameter window.
2. Waveform of PLETH in waveform section.
3. The oxygen saturation value (SpO2%) in the SpO2 parameter
window.
The PR value is only displayed in the ECG parameter window if:
1. SpO2 is selected in the HR DA setting in the ECG SETUP menu.
2. If AUTO is selected in the HR DA setting in the ECG SETUP menu,
no ECG signal is received.
As shown in the figure below, the PLETH waveform is on the left and
the SpO2 parameter window is on the right. The SpO2 value is given
as a percentage, followed by the perfusion rate (proportional to
the pulse intensity). You can also access the SpO2 Settings menu
from the SpO2 tab in the upper left corner of the parameter window.

SpO2 monitoring is a noninvasive technique for measuring the amount
and pulse rate of oxyhemoglobin by measuring the absorbance of
selected wavelengths of light.
The light produced by the researcher travels through the network
and is converted into an electrical signal with a
PHiliphhilipotodetector in the researcher's house. The SpO2 module
processes the electrical signal and displays the digital SpO2 and
waveform and pulse values on the screen.
The measuring wavelength of the sensor is nominally 660 nm for red
LEDs and 940 nm for infrared LEDs. The maximum LED output power is
4 mW.

Spo2 Monitoring Procedure
The choice of sensor for SpO2 measurement depends on the type of
patient. Finger SpO2 sensor is selectable for adult patients. For
newborns, you can choose a hand or foot sensor. See the steps
below.
1. Turn on the screen.
2. Attach the sensor to the appropriate location on the patient.
3. Connect the sensor extension cable connector to the SpO2
connector on the monitor.
Spo2 Measurement Limitations
If the accuracy of any measurement seems unreasonable, first check
the patient's vital signs by an alternative method. Then check if
the instrument is working properly. Inaccurate measurements can be
caused by:
Faulty SpO2 sensor;
- high-frequency electrical noise, including noise generated by the
host system, or noise from external sources, such as electrosurgery
equipment connected to the system;
- Oximeter and SpO2 Sensors Used During Magnetic Resonance Imaging
(MRI)
- scan. The induced current can cause burns;
- Intravascular dye injection;
- Excessive patient movement;
- Excessive ambient light;
- Incorrect sensor installation or wrong sensor placement on the
patient
- Sensor temperature (optimal temperature between 28°C and 42°C);
- Sensors placed on limbs connected to blood pressure cuffs, arterial
catheters, or intravascular lines;
- Dysfunctional hemoglobin concentrations, such as carboxyhemoglobin
and methemoglobin;
- SpO2 is too low;
- Low circulatory perfusion in the applied part;
- Shock, anemia, hypothermia, and vasomotor application all reduce
arterial blood flow and may affect pulse oximetry.
