Using a more powerful chip, the blood oxygen pulse signal capture is more accurate, and the calculation ability is strongerBlood oxygen saturation is an important physiological parameter of breathing and circulation. A normal adult blood oxygen parameter lower than 95% can be judged as insufficient oxygen supplyOperation steps: 1. Load AAA batteries according to the positive and negative signs in the battery compartment and close the battery cover. 2. Pinch open the clamp, insert your finger into the hole (full finger extension), and then press the button on the panel. 3. During use, the tested finger should not shake or move the human body. 4. Read the relevant data directly from the display screen. The high-performance acceleration sensor is used to shorten the measurement time. It only takes 8 seconds to display the parameters such as blood oxygen, pulse rate, and pulse intensity. The intelligent system recognizes and judges. If there is no measurement response within 15 seconds, the blood oxygen finger clip will automatically shut down, increasing the service life.
