General Description

Oxygen saturation indicates the percentage of hemoglobin in arterial blood that is loaded with oxygen. This is a very important parameter for the respiratory circulation system. Many respiratory diseases can result in lower oxygen saturation within human blood. Following factors can reduce oxygen saturation: Automatic regulation of organ dysfunction caused by anesthesia, intensive postoperative trauma, injuries caused by some medical examinations. These situations may result in light-headedness, asthenia and vomiting. Therefore, it is very important to know the oxygen saturation of a patient so that doctors can detect problems in a timely manner.

Measurement Principles

Principle of this fingertip pulse oximeter:
A mathematical formula is established making use of Lambert-Beer Law according to spectrum absorption characteristics of deoxygenated hemoglobin (Hb) and oxyhemoglobin (HbO2) in red and near-infrared zones.
Operation principle of this device:
Photoelectric oxyhemoglobin inspection technology is adopted in accordance with capacity pulse scanning and recording technology so that two beams of different wavelengths of light (660 nm red and 905 nm near-infrared light) can be focused onto a human nail tip through a clamping finger-type sensor. A measured signal obtained by a photosensitive element, will

•  The device must be able to measure the pulse properly to obtain an accurate SpO2 measurement. Verify that nothing is hindering the pulse measurement before relying on the SpO2 measurement.
•  The maximum application time at a single site should be less than 30 minutes, in order to ensure correct sensor alignment and skin integrity.

Inaccurate measurements may occur if:

•  The patient suffers from significant levels of dysfunctional hemoglobin (such as carboxyhemoglobin or methemoglobin).
•  Intravascular dyes such as indocyanine green or methylene blue have been injected into the patient.
•  Used in the presence of high ambient light (e.g. direct sunlight). Shield the sensor area with a surgical towel if necessary.
•  There is excessive patient movement.
•  The patient experiences venous pulsations.
•  The patient has hypotension, severe vasoconstriction, severe anemia, or hypothermia.
•  The patient is in cardiac arrest or is in shock.
•  Fingernail polish or false fingernails are applied.

Inserting the batteries

After you have unpacked your device, first insert the batteries. The battery compartment is on the bottom of the device. Remove the battery cover by sliding it in the direction shown. Insert the batteries (2 x 1.5 V, size AAA), thereby observing the indicated polarity.

ON/OFF button / Function button

Press and release the ON/OFF button 1 to turn on, hold the button for about one second. The device shows the settings menu AT. Press or hold the ON/OFF button to perform corresponding operations. Hold it to set an item, or press it to switch an option or switch the display mode. Press means no more than 0.5 seconds, while hold means more than 0.5 seconds.

Alert Sound Setting
Hold ON/OFF button 1 while the device is switched on. Settings menu (interface

1. is displayed AT-a. Move «» to the corresponding option, and hold the function button to set Alm to on and set Beep to off. When Alm is set to on and the measured values of the blood oxygen saturation and pulse rate go beyond the upper limit or lower limit, the device gives off an alert sound. When Beep is set to on, a tick will be heard along with pulse beats during pulse rate measurement. While the «» symbol stays on the Restore option, hold the functional button to restore default settings.

Brightness Setting
Press ON/OFF button 1 to select the Brightness option and then hold the ON/OFF button to set the brightness to a value ranging from 1 to 5. The greater the value, the greater the brightness of the screen.

Alert Range Setting
On settings menu (interface 2) AT-b, press the ON/OFF button 1 to switch between options. On this interface, you can set the upper limit and lower limit of SpO2 Alm and PR Alm. While the «» symbol stays on the +/- option, hold the functional button to set the option to + or -. In + mode, select the corresponding option and hold the ON/OFF button to increase the upper or lower limit; in – mode, hold the ON/OFF button to decrease the upper or lower limit. Move «» to the Exit option, and hold the ON/OFF button to return to the monitoring interface.

Display Mode

When the device is switched on, shortly press the ON/OFF button 1 to switch to another display mode to select your desired display mode 9. There are 6 different display modes. The default setting is mode 1.
