Zero Oxygen Saturation in Pulse Oximeter: Need for Clinical Correlation

Sir, I would like to share an unusual incident, which had happened recently in our operation theater. This event had occurred while conducting spinal anesthesia for a 28-year-male patient with an inguinal hernia for meshplasty. His preoperative anesthetic evaluation and investigations were unremarkable. In the operating room, the blood pressure (BP) cuff and pulse oximeter were applied in the s...

A Three-Wavelength Pulse Oximeter for Carboxyhemoglobin Determination

Pulse oximetry measures the relative concentration of arterial oxygenated hemoglobin and reduced hemoglobin. This paper presents the design of a pulse oximeter, which measures the presence of a third substance, carboxyhemoglobin (HbCO), by unfiltered LEDs at 660 nm, 810 nm, and 940 nm. Background information is given on the theory of pulse oximetry. Theoretical approximations and calculations w...
