Package Contents: -Finger clip pulse oximeter x 1 -Color box x 1 -Certificate of conformity x 1 -English user manual x 1 Monitoring parameter SpO2: Oxyhemoglobin saturation (SpO2) Patient type: applicable to all persons over 4 years old Measuring range: 0-100% Resolution: 1% Accuracy: 70-100%±2% Oximeter saturation: an important indicator that reflects the oxygen status in the body. It is generally believed that the normal value of blood oxygen saturation should not be less than 94%, and it is regarded as insufficient oxygen supply below 94%. Heart rate/pulse repetition frequency (PR) BPM: Measuring range: 30bpm-250bpm bpm solution: 1 Accuracy: 1% or 1bpm Heart Rate (Heart Rate): refers to the number of times the heart beats per minute. It means how fast the heart beats within a certain period of time. The same person, his heart rate slows down when he is quiet or sleeping, and his heart rate increases when he exercises or is emotionally excited! Instructions: 1. Insert two (AAA) batteries according to the positive and negative signs in the battery compartment and close the battery cover 2. Pinch open the finger clip pulse oximeter clip 3.

Don't shake your fingers during use, and don't keep your body in motion 6. Read the relevant data directly from the display screen, and the display screen can display blood oxygen saturation, pulse rate and pulse amplitude 7. After booting, the interface direction switching mode defaults to gravity sensing mode, and it can also be switched to button mode. In the gravity sensing mode, the display direction will automatically switch according to the direction of gravity. Precautions: 1. Avoid exposure or direct sunlight 2.

This instrument is not suitable for babies and newborns, but only for children and adults over 4 years old. 7. The pulse rate waveform is normalized, and when the pulse rate waveform tends to be smooth and stable, the measured value read is a normal value, and the pulse rate waveform at this time is also standard. 8. The fingers of the tested person should be clean, and nail polish and other cosmetics should not be applied to the nails 9. Insert the finger into the rubber channel, and the fingernail must face up, in the same direction as the display
