Comparison of SpO2 values from different fingers of the hands

Pulse oximetry is a frequently used tool in anesthesia practice. Gives valuable information about arterial oxygen content, tissue perfusion, and heartbeat rate. In this study, we aimed to provide a comparison of peripheral capillary hemoglobin oxygen saturation (SpO2) values among every finger of the two hands. Thirty-seven healthy volunteers from operative room stuff between the ages of 18–30 years were enrolled in the study. They were monitored after 5 min of rest. After their noninvasive blood pressure, heart rate, fasting time and body temperature were measured, SpO2 values were obtained from every finger and each of two hands fingers with the same pulse oximetry.All the SpO2 values were obtained after at least 1 min of the measurement period. A total of 370 SpO2 measurements from 37 volunteers were obtained. The highest average SpO2 value was measured from the right middle finger (98.2 % ± 1.2) and it was statistically significant when compared with the right little finger and left middle finger. The second highest average SpO2value was measured from the right thumb and it was statistically significant only when compared with the left middle finger (the finger with the lowest average SpO2 value) (p
