Three types of spO2 sensors for option Handheld Pulse Oximeter

Introduction

Handheld Pulse Oximeter by driving a red LED (660nm) and an infrared LED (910nm) in turn, the blue line indicates the induction curve of the receiving tube to the reduced hemoglobin when the hemoglobin does not carry oxygen molecules. The absorption of light is relatively strong, while the absorption length of 910nm infrared light is relatively weak. The red line indicates the induction curve of the receiving tube to oxyhemoglobin when hemoglobin and red blood cells with oxygen molecules are present. It can be seen from the figure that the absorption of red light at 660 nm is relatively weak, and the absorption of infrared light at 910 nm is relatively strong. During blood oxygen measurement, the difference between the reduced hemoglobin and the oxygenated hemoglobin by detecting the difference between the two types of light absorption at different wavelengths is the most basic data for measuring blood oxygen saturation. In the blood oxygen test, 660nm and 910nm are the two most common wavelengths. In fact, to achieve higher accuracy, in addition to two wavelengths, even up to 8 wavelengths, the main reason is that human hemoglobin is not only reduced to hemoglobin. In addition to oxyhemoglobin, there are other hemoglobins. We often see carboxyhemoglobin. More wavelengths will help you to do better precision.

expected usage

• This product is intended for monitoring blood oxygen saturation (spo2), pulse rate (pr) and pulse strength.
• The oximeter monitors these physiological signals of the patient by using the blood oxygen probe, and further processes them, and then displays the numerical results on the LCD screen, or displays the numerical values on the PC or smartphone through wireless Bluetooth.
• Evaluation of test results: From medical analysis, the oxygen content in the blood is greater than or equal to 95, which is a normal indicator; the pulse per minute is between 60-100 times, which is a normal indicator.

• If the values you have tested do not meet the above two indicators, please test 2-3 times at different time points, and keep 2-3 continuous tests. If the values still do not meet the standards, it is recommended that you go to the hospital for detailed information. Seek sickness.
