Perfusion Index ( PI)
PI is the Index Perfusion (PI), PI value reflects the pulsatile flow of blood, that is reflected Blood flow perfusion ability. The greater the pulsation of the blood flow, the more pulse component, the greater the value of PI. Therefore, measurement Site (skin, nails, bones, etc.) and the patient's own blood flow (flow of blood)
will affect the value of PI.

What is the ODI4?
Oxygen Desaturation Index of 4 Percent
ODI can be better to reflect the severity of SAHS.
An elevation in ODI may lead to increased oxidative stress in the body that may predispose people to long-term cardiovascular risks, including high blood pressure (hypertension), heart attack, stroke, and memory loss associated with dementia.
ODI4 indicates the severity of hypoxia during sleep, if this number is greater than 5, please go to the hospital for further examination

What is SAHS
Sleep apnea is a condition in which breathing stops for more than ten seconds during sleep. Sleep apnea is a major, though often unrecognized, cause of daytime sleepiness. It can have serious negative effects on a
person's quality of life, and is thought to be considerably underdiagnosed in the United States.

Polysomography (PSG) is the gold standard for the diagnosis of SAHS, but the operation is complex and cost much, it is not easy to popularize.
