Why I get different readings by Oxygen Monitors of Wellue and other manufacturers?
Different manufacturers utilize algorithms with different average SpO2 times, which is a significant element when calculating the reading. The shorter the collecting duration, the more sensitive the result, the fast the response. Oxygen monitor with too long assessment time is not the best choice for oxygen saturation detection, especially during sleep. Wellue’s intelligent averaging algorithm collects data quickly and identifies the precise SpO2 value.
Therefore, it is not rigorous to compare oxygen monitors that utilize different averaging algorithms.The comparing result will be much more accurate if obtained by an arterial blood gas.
