Monitoring parameter SpO2: https://kiuzou.1688.com
Oxyhemoglobin Saturation (SpO2)
Patient Type: For all persons over 4 years old
Measurement range: 70 - 99%
Resolution: 1%
Accuracy: Within 70% - -99%±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 lower than 94%, and below 94% is regarded as insufficient oxygen supply.
Heart Rate Pulse Repetition Rate (PR) BPM:
Measuring range: 30 bpm - 250 bpm
bpm solution: 1
Accuracy: 1% or 1 bpm

Heart Rate (Heart Rate): refers to the number of times the heart beats per minute. That is, in a certain period of time, the heart beats fast or slow. In the same person, the heart rate slows down during quiet or sleep, and increases during exercise or agitation!

Blood perfusion indicates PI value:
Measuring range 0.2%-30% PI
Resolution: 1%

PI refers to the perfusion index (Perfusion Index, PI), and the PI value reflects the pulsatile blood flow, that is, the blood perfusion ability. The greater the pulsatile blood flow, the greater the pulsatile component and the greater the PI value. Therefore, both the measurement site (skin, nails, bones, etc.) and the patient's own blood perfusion (arterial blood flow) will affect the PI value. Since sympathetic nerves affect heart rate and arterial blood pressure (affecting pulsatile arterial blood flow), the body's neuromodulatory system or mental state also indirectly affects PI values. Therefore, under different anesthesia states, the PI value will also be different.

Respiratory rate monitoring function RR value:
Respiratory rate is a medical term for the number of breaths per minute, and one rise and fall of the chest is one breath, one inhalation and one exhalation. The number of breaths per minute is called respiratory rate. Respiration is the process of gas exchange between the internal and external environment of the human body. The human body inhales oxygen and exhales carbon dioxide through breathing to maintain normal physiological functions.
A normal adult breathes about 16-20 times per minute. The ratio of breath to pulse is 1:4, that is, for every breath, the pulse beats 4 times. Children breathe faster than adults, up to 20 to 30 times per minute; the respiratory rate of newborns can reach 44 times per minute. Breaths per minute. Respiratory rate varies with age, gender, and physiological status.
