4. Take your finger out of the clip, and it will automatically shut down after about 8 seconds.

What is a pulse oximeter?

The Finger Pulse Oximeter is an affordable and accurate method of detecting pulse rate and oxygen saturation through the finger. The page can display a volumetric waveform graph to ensure accuracy. The special PI index can effectively reflect the pulsating blood flow in the body. The simple one-button design is easy to operate, and the screen is an OLED LCD display, which is small and easy to carry. Suitable for daily use, measure your health status at any time.

Widely used in families, hospitals, oxygen bars, sports health care (used before and after exercise, not recommended for use during exercise), community medicine, and other ranges. The lk87 pulse oximeter is suitable for highland travel as well as mountain climbing enthusiasts, patients (patients recuperating at home for a long time or in emergency situations), elderly people over 60 years old, people working more than 12 hours a day, sportsmen (professional sports training or sports enthusiasts), workers in confined environments, etc.

Oximeter measurement index reference

Monitoring parameters SpO2.
Oxygenated hemoglobin saturation (SpO2)
Patient type: For all persons over 4 years of age
Measurement range:70 – 99%
Analysis: 1%
Accuracy: At 70% – -99% ±2%

Oximetry saturation: An important indicator reflecting the oxygen status in the body. It is generally believed that the normal value of oxygen saturation should be no less than 94%, and below 94% is regarded as an insufficient oxygen supply.
Heart rate Pulse repetition rate (PR) BPM:
Measurement range:30 bpm – 250 bpm
bpm solution:1
Accuracy:1% or 1 bpm
Heart Rate (HR): is the number of times the heart beats per minute. It also means how fast or slow the heart beats in a certain period of time. In the same person, the heart rate slows down during quiet or sleep and speeds up during exercise or emotional stress.

Perfusion indicator PI value:
Measurement range 0.2% – 30% PI
