The first time you use the finger oximeter, press the Reset button, the LCD screen shows the standby status.
Press the opening of the clip. Put the middle finger of your left hand or right hand into the working compartment (you can see the infrared light inside the compartment, pay attention to: the finger should not be crooked, not wet, not the surface of the nails have foreign objects).
To be completely contact with the finger and the work of the warehouse, the LCD display detection process. (Note that, into the detection state, to maintain the stability of the inspected finger, do not shake up and down, left and right)
30 seconds later, release the mouth of the clamp, the finger out of the work of the warehouse, the LCD fixed test results. The %SpO2 at the top of the screen is the blood oxygen index. Min is the pulse rate at the bottom of the screen.
2, the principle of finger oximeter
Finger oximeter using light-emitting diodes, emitting red and infrared light, through the finger skin and musculoskeletal tissues of the brightness, detection of human blood oxygen saturation and pulse rate, safety, precision, accuracy, in full compliance with the EU CE standards. Finger oximeter is small in size, light in weight, easy to carry, simple and convenient, low power consumption.
3, oximeter finger clip calibration method
Function test device can not be used to assess the accuracy of oximeter. Set Tech to 1 and R curve to 2, then the user can use this special standard curve to calibrate the oximeter. Clinical testing is a common method used to determine the accuracy of oximetry. The oxygen saturation of arterial hemoglobin measured by oximetry is compared to the determined results of sampled arterial blood analyzed by the CO-oximeter
