The Main Measurement Indicators Of The Oximeter Are Pulse Rate, Blood Oxygen Saturation, And Perfusion Index (pi). Blood Oxygen Saturation (oxygen Saturation Abbreviated As Spo2) Is One Of The Important Basic Data In Clinical Medicine. Oxygen Saturation Refers To The Percentage Of The Combined O2 Volume In The Total Blood Volume To The Total O2 Volume That Can Be Combined.
According to medical analysis, the oxygen content in the blood is greater than or equal to 95, which is a normal indicator; the pulse rate is between 60-100 beats per minute, which is a normal indicator. If your detected values do not meet the above two indicators, please test 2-3 times at different time points and keep the continuous testing for 2-3 days. If the values still do not meet the standard, it is recommended that you go to the hospital for detailed consultation.
CE FDA OLED Fingertip Pulse Oximeter
-Long battery life
finger pulse oximeter drives a red LED (660nm) and an infrared LED (910nm) in turn. The blue line represents the induction curve of the receiving tube to reduced hemoglobin when hemoglobin does not carry oxygen molecules, as can be seen from the graph Lower reduced hemoglobin has a relatively strong absorption of 660nm red light, while the absorption length of 910nm infrared light is relatively weak.
So how to judge pulse oximeter is good or bad?
- Some manufacturers’ products come with quality control fluids and test cards to specifically test the accuracy of the oximeter and whether the oximeter is working properly.
- The size and clarity of the display screen, whether it is convenient to replace the battery, whether the appearance is beautiful, and the size, etc., should first be clear about the accuracy.
- Look at the warranty items and other after-sales services and services, and understand the warranty period of the oximeter.
- When choosing an oximeter, not only the price of the instrument, but also the cost of consumables.
