Following the first development in its modern form in 1972 by Takuo Aoyagi [1], pulse oximetry has become invaluable for monitoring oxygenation and pulse rate [4]. A constant amount of light (DC) from the pulseoximeter is absorbed by skin, other tissues, and nonpulsatile blood, while a variable amount of light (AC) is absorbed by pulsating arterial inflow… CONTINUE READING
